I am waiting on some parts to arrive, so I decided to start working on the Morse Docking lights. They are designed to have the entire eye-ball assembly replaced. I managed to get it open, but wound up breaking the light before getting it out.
The light is a GE 4419 Marine floodlight, Par36, 100w with a 25hr service life. This means it pulls around 8.5A running. I want to replace it with an LED, but I’ll have to get this assembly apart.
The eyeball is press-fit together and the silver ring is what holds it together. I managed to pry it apart. The light itself sits in a rubber ring and that is held in by the silver ring which is pushed in behind it. I have not quite figured out how to extract the ring yet.
Here is an update from this weekend on the high-stop lights. I’m nearly done with the bus lights and just waiting on a couple of 24v to 12v stepdown transformers to arrive.
Here is one of the fabricated mounting brackets, primed and painted.
Here are both of them with the lights mounted on them.
Here they are with the wiring spliced.
I am sealing them in with silicone caulk. It’s simple and it excels at this purpose.
After the install I wipe up the excess and it looks darn good.
Here is what I am replacing, a Hella light.
The inside is pretty worn out.
This one had a busted bulb in it.
The wiring is okay, but doesn’t look factory. There is an interesting rubber seal that the light mounts to. I had to cut it to get rid of it.
I always test the lights before sealing them in.
And here is another view showing the curb side completed. Looks great and I shouldn’t have to mess with it for a while.
I had a devil of a time rounding the corners on 1/4″ T6061 aluminum plate when I fabricated the rear light assemblies. I decided not to do that again for the upper or high-stop plates.
I am making plates so that my LED surface mount lights have somewhere to mount to. I am rounding the corners so that they fit into the fiberglass holes from the old incandescent lights.
I ordered the metal from OnlineMetals.com. They were quick and it showed up cut exactly to the right dimension on both the lower and upper light plate orders.
I then drilled holes and drilled and tapped screw holes for the LED lights.
However, I needed to round the corners. A CNC Mill would be ideal, but I don’t have one anymore. You can see my old one here: https://www.youtube.com/watch?v=Sae6_1ZaIPw
What I do have is a DeWalt MaxXR jigsaw like this one:
DEWALT DCS331B 20-Volt MAX Li-Ion Jig Saw
Regular metal blades gum up in aluminum and then they don’t cut worth a damn. So I did some research and found that DeWalt makes some aluminum and fiberglass blades that are supposed to go through metal like butter.
DEWALT DW3755H 4-Inch 8 TPI Aluminum/Fiberglass Cut HCS T-Shank Jig Saw Blade (5-Pack)
I ordered a set on Friday and they were delivered Sunday via the US Postal Service. Prime is really handy.
They are not quite like going through butter, but they are definitely an improvement over standard metal blades that are designed for steel.
I finally got the headlights mounted, installed, and wired. On the downside, I apparently forgot to take pictures Friday evening. I’m not entirely happy with the way they are mounted. The Neoplan / Auwarter fiberglass front trim is angled. I’m actually impressed that the original headlights worked as well as they did. The wiring harnesses were a mess.
I ordered some nylon spacers from BoltDepot to try and straighten out my Nissan Pathfinder headlight buckets. Headlight buckets are the metal assemblies that the headlight itself mounts in. They contain the adjusters and fasten to the body of the vehicle. I ordered a pair of them on eBay for $22 including free shipping. I guess they are frequently replaced on eBay. The problem I have right now is that they are toed out too much.
I chose to keep the square look, although it would have been much easier to purchase some Dietz 7 inch black headlight buckets like these and then the 7″ truck-lite LED’s like these for Jeep’s.
Truck-lite’s throw off a ton of even, well balanced light. Amazon has a good listing for them here:
Truck-Lite (27270C) Headlamp
The one I actually used is this one:
Truck-Lite (27450C) Headlamp
One of the nice things about eBay and the US Postal Service is that things show up pretty quick. I received the marker lights I ordered Sunday today, Wednesday. I had some time after work and before it got too late, so I took advantage of it to get the lights installed in the front and mid section upper areas. For the most part it went smoothly and all of the lights are bright and working great.
This first picture is the rear marker LED’s. The brake lights are about 5x this bright when they fire off. It’s looking really good back there.
This is a sideview of the driver’s side showing the upper front, mid, and rear markers along with the midship side marker. The additional side markers are not hooked up right now.
Here is the curb side, sorry it’s a little blurry.
And here is the front of the coach. There are 5 lights across and two Beehive markers. One of the less pleasant things I found up there were some hornet/wasp nests in the space where the windshield wiper arms live. I made a note to myself to watch out for angriness® when the weather improves and the coach sits for any length of time.
I need to do the 3 rear red markers and the high stop/marker lights. The evolution of middle stop/marker lights is pretty interesting. As I understand it they tested several approaches in the US before settling on the middle light that is now somewhat standard on passenger vehicles. At any rate, they don’t do any harm and they increase the visibility for vehicles following me so I am going to keep them and upgrade them to LED’s. I had to order aluminum plates and those should be in tomorrow via UPS.
As for the lights themselves, I had ordered some Maxxima mini markers and when they came in I concluded they were entirely too small for a retrofit project. They will probably be good for something, just not this project. I wound up ordering some Optronix LED’s which were $6/ea including free shipping. It’s amazing how inexpensive these lights are getting. I ended up using a pair of them for my upper mid markers because I thought they would put off a decent amount of light. I was right and it saved me some money in the process.
I will use the red mini markers as rear side markers to upgrade the lighting to current regulations. This is not required, but it makes good sense. I may recycle the Amber mini reflectors somewhere along the side as well.
Among my many projects, the cab light had 24v bulbs in it. That was fine, but it also shares it’s circuit with the marker lights. I’ll eventually figure out why, but now that the circuit has been converted to 12v it makes the bulbs pretty dim.
I carefully pried the cover off of the fixture and installed a pair of 12v LED bulbs that I had bought for the coach. I originally was going to install them in my road lights. However, after finding abundant corrosion there I decided to rework all of the lights and embarked on a major project.
They are not quite as bright as the 28v bulbs, but they are plenty bright for finding something or reading a map. I expect most maps to be on my iPad anyway.
One thing I did not do was mess with the wiring. I don’t like that the cab light only works when the marker lights are on. I’m okay with it being on the run circuit, but I want the ability to turn it on independently as long as the key is in.
This past weekend I knocked a few things out that were on my to-do list. The first one was getting the driver door window to where it would operate smoothly. When I bought the bus I drove it home with a 1 inch gap in the window. I was afraid that if I forced it the window might break, so I left it alone. I finally got around to forcing it and getting it going again.
The culprit was bits of glass in the track. It appears that someone broke out the window and the safety glass shattered and fell into the track. It was a pretty easy fix with some brute force, silicone lube, and a shop vac.
Now I can open or close the window all the way. That will make life easier when I’m driving it. There still isn’t any coach air working. The heater doesn’t work for that matter either. One thing at a time. Right now I’m working on getting the coach ready to pass road inspection and get license plates.
So I moved to the front of the coach and started working again. The curb side turn signal has not worked since I bought the bus. I brought out my signal and tracer unit and started trying to follow the wire. I concluded that there was a break somewhere under the dash. This is just great because the dash is like Houdini’s last escape.
I would absolutely love to remove it, but that doesn’t look like it’s possible without alot of headache. The drivers console is screwed to the dash cover and it seems to be what supports it. I’m not quite that frustrated or that brave. The picture below shows one view of what I was working with.
I thought that the wire was broken behind the wiper motor, so I managed to get enough of it loose to get it out. I was wrong, it was much closer to the end of the wire.
In the photo above the break is between the two places where the green wire is visible. Had I looked closer I would have easily found it. But I insisted on stripping all of the wire loom cover off of it.
Which is just as well. It revealed the wound where someone had drilled into the wire and cut through 2 strands and severely damaged several others. It’s a wonder it conducted electricity honestly. Wire is cheap, so this is an easy fix now that I have found the problem. As you can see in the picture it was getting dark, so this will be tomorrow’s funitivity! I did pull it apart to survey the extent of the damage. It’s not too bad, just a few feet of wire will need to be spliced in. I’ll need to trace and label all the wires at this point and may replace everything downstream of here anyway.
This morning I resumed work on the rear lights. I’ve been working for a few days now on tracing what wire does what back there. The wires have labels, but they have been painted and I don’t have a schematic. So everything is hunt and find.
Here I’m using a multi-meter and some alligator clips to check wires.
I finally gave up and concluded that the original wiring harness had some faulted wires. I cut the entire harness out and it made very short work out of identifying the remaining wires and labeling them. I’ll have to build some sub-harnesses to reach my new assemblies, but that won’t take as long.
Somewhere in the picture below is a broken wire… maybe more than one. I got frustrated and cut them out.
The brake light and reverse light need to stay 24v. So that requires stepping them down at the “tailgate.” I ordered a couple of small step-down transformers on AliExpress. They promise to be waterproof and capable of 5A. 5A is a tremendous amount of current and I’m only going to push maybe 1A through them, so this should work just fine. You can view the listing here. Unfortunately, Alibaba thinks they are being clever by stopping you from copying the images…. but what they are really doing is hurting the ability of bloggers like me to reference them. At any rate they are fully potted step down voltage regulators. They should be just fine for this application and I ordered and extra one just in case.
So I started on mounting the light cans to the front trim tonight. For those of you just finding this post, let me bring you up to speed on the project. My Neoplan Bus based RV has 1985 German / Euro spec signal, marker, and headlights. They are nice units made mostly by Bosch and Hella. Unfortunately, the headlights are worn out, have cracked lenses, and are miswired severely.
So I opted to install standard H4/H11 Truck Lite LED units. I could have installed non-LED’s, but I would have had to mess with converting them to 12v. The trucklite’s can handle 24v. This works out to be easier and simpler and avoids the question of what capacity the wires are. If they could handle halogen 24v they will be fine on LED 24v.
One challenge is that the lights don’t mount the same. I learned that the mounts are called buckets or cans. They are semi-standardized, so I ordered some on eBay for $25 including shipping. They required light modification to make them fit. No big deal. I clipped off a piece and drilled holes sized for 10-24 machine screws. Unfortunately, I don’t have the right length screws on-hand. I figured I could pick them up locally at HomeDepot, but they don’t apparently know what they have. This isn’t really a big surprise, the hardware aisle is always a wreck. I usually use the order-online, pickup-in-store. I got a call this morning that they couldn’t find the 1.5″ or 1.25″ screws that I ordered. Shrug, just an excuse to stock up on hardware from BoltDepot. I will try to take some pictures this weekend.
The net of it is that it is going together nicely. I ordered some driving lights on alien press and have yet to see them….. Hopefully they will show up before long. They are LED 10w units.
