- Continuing with the Mechanical work and the smart turn signal controller I successfully removed all the front end components, and I got my Arduino controlled blinker unit fully functional! Good stuff, and a great episode. Enjoy!

those old motorhomes were way ahead of their time when they were made. My uncle had one when I was a kid.
However they're never going to be good at high altitude with a carburetor and adding fuel injection is easy enough but the hard part is the fuel mileage. Your never going to get fuel mileage with a 3-speed automatic unless you keep your speed under 55 all the time. But those things are brilliant. A masterpiece of General Motors😊

On your rusted steering part and rusted brake master cylinder, there's a product called POR 15 it's a paint over rust product that neutralizes rust and covers it in chassis black color.
the side marker are allowed to be out of phase with the front and rear blinked, i know because both on my 1977 chevy G10 van and 1988 chevy s10 truck the side makers do blink out of phase when turn signals are on. Since its factory for many 1970s and 1980s GM vehicles it has to be allowed, and I think it looks pretty and and also helps people's awareness when one is changing lanes.
Side note for those playing with LED bulbs on these older GM vehicles. With these GM's of 70's and early 80's when you add LEDs sometimes they do not work correctly when you have your parking lights or headlights on at night, even when you change the turn signal blinker relay on the fuse box to a newer one made for for LED. .On both my 77 and 88 I added LED bulbs everywhere but I leave the standard incandescent bulbs in the front signals. If I change those to LED's then the always something screwy happens like the front turn signals stay solid without blinking. .
So they do make different style blinker relays that use a different "solid state" method and do not use the heated filament method to make the turn signals blink. Check out Napa or Oreiley's and you can find them for most any 70's or 80's car. they last longer and can handle more loads when you add trailers and more lights on a vehicle.
Oh you're an architect. I'm further along in the video now and you mentioned that. I also saw the one where you drove across country😮
Just an FYI: The Cadillac service manual for the Eldorado with the same front wheel drivetrain configuration says to replace the six 12 point bolts that holds the axle to the inner diff adapter, not to reuse them if you take them apart.
Good to know. Thanks.
Does it give a torque specification?
@@IndustriousPursuits The spec is 65 ft/lb. Let me know if you need any of the other suspension fastener torque specs.
RE: beating out bolts with your hammer. I try and put a nut on the end of the stubborn ones. Keeps the bolt from mushrooming wider than the hole.
Evapo-rust gel for that pitman arm and brake cyl. Brush it on the rusty areas, let it work, then wash off with water. Dry them then paint.
Just goes to show. They were built to last. (Way ahead of there time. Just like the 747 Jumbo). After you are finished. Should last another 45 years. Happy travels.
Awesome videos you've been doing..... I'm working on my 77 Royale thx for all videos!!
If you search around they make a lot of 2 piece boots for that steering shift and cv axles and lots of things that utilize boots so you don't have to remove the entire part
Looking great, Matt!
I fell deep down the arduino rabbit hole while trying to build secure cabinets in our ambulance conversion. The system works flawlessly now, but it took months on head scratching and debugging. KISS is a great engineering principal, but FLOSS is a great life principal. Cheers!
stopping brakes from draining when changing the lines. picking up the proper sized inverted flare union and an inverted flare plug.. can seal the ends of the hard lines..
You can use the relay activated on the signal before the flasher relay to disconnect the running lights when indicators are turned on and it should solve all of your problems.
Enjoy all your videos. always look forward for the next one.
We're all glad to see some traction on this project!
13:53 Heeeeyyyy 👍👍👍 hope they work for ya 👋👋👋
I don't think you will be happy with the two LED side marker lights. If one LED is on (Park Lights) and the second LED is flashing (Turn Indicator), because both LEDs are the same intensity, I do not think you will be able to see the flashing LED very well.
There is a tool for unloading the torsion bars, it saves the threads from wearing out as it's not good to turn them under load. Oh, and the hub drive bolts are called Ferry bolts, or commonly 12-point bolts. My newish brake reservoir/master cylinder is just as rusty
Simple solution from Mustie1: chain oil diluted with some kerose. It dries smooth and protects from more rust.
He and I use it to rustproof frame rails and underbody. Very effective. Just my two cents.
Something like this will probably be my future home solution.
thanks for sharing all of this info about the lighting! It has really helped with the projects I'm currently working on as well!
Also saw you were having issues w the 3D prints. would it help if you sprayed them with some sort of reflective paint that can help reflect more of the light and heat?
Good job as always I cant wait to see whole bus painted
Also I just had the transmission fully rebuilt and painted as well as the motor. The motor is still in the shop. should be done in a week or so.
I know it's an old video but I'm a new viewer. I love those old motorhomes and I think you're doing a great job and learning a lot as you go. What is your job are you an engineer of some sort?
Keep It Clean 10853 Flasher No Load Fixed Flasher
Keep It Clean 10853 Flasher No Load Fixed Flasher these have been around to replace the bi metal flasher since the 70s
Reading this comment I realized that I'm going to have a problem. Once I replace the rear incandescent bulbs with LEDs the stock flasher will stop working! Thanks for the heads up!
@@IndustriousPursuits the l.e.d compatible flasherunits are also used on motorcyles when aftermarket l.e.d indicators are fitted
I have lots of parts for sale. I have a 1976 completely torn down. Powdercoated the frame and the entire front end. Also powdercoated the boogie arms and have all new hardware. Let me know if you are interested.
me mate sent me a link to ur videos about a year ago saying "he's gonna ruin it". i think the opposite actually. i like the modern solutions
Just get the new electronic version of the signal light relay...gonna need it anyways as the LEDs will flash to fast with the old flasher relay.
As a Design Engineer myself - I have to comment as you refer to the KISS method several times in this video and others - yet, you want to 'redesign' a whole bunch of different "off-the-shelf" items. Like the tank vents - the kitchen stove vent grill, the turn signals, etc. All - off the shelf easily replaceable components. yet you want to reinvent the wheel it seems. not sure I follow why. With that said, I did like the side vent cover design with the recessed louvers. but the roof vent - again, if it breaks - you can't go to any store and buy it - you have to print a new one, etc. that's not kiss in my opinion. also - any of those 3D printed parts, as I'm sure you know - should be painted for UV protection....or they will likely fail in short time. especially something like the mirror mounts with that wind load on them. appreciate the videos regardless - as I am hoping to pickup my GMC here in a few weeks after bank processing paperwork.
essentially you're making a record. and we get to watch or use it for our GMC. It will be much better when it's all done. But some like me don't mind the wait.
I see a potential legality issue with your front running light/turn signal, the one integrated with the headlight. I read some where, and have seen in real life, that if the running light and turn signal are within a certain distance of each other, then they must use a special flashing pattern. Specifically, if the running light is on, then when the turn signal is activated, the running light must turn off and stay off while the turn signal flashes on and off. Once the turn signal is finished flashing, then the running light can turn on again. I believe this is to make the turn signal flashing more noticeable. The ideal is that what is essentially one lamp switching back and forth from white to amber is not as distinct as flashing from off to amber.
Here is the Jalopnik article that explains it.

Fantastic! Thank you!
Here is the Orientation video for the GMC Motorhome it shows the 3 roof vents. It looks like the rear most one on the passenger side is for the discharge tube. The other two are for the sink on the driver's side and the black water tank, or the shower (?), on the passenger side.

You can stop the flow of brake fluid from the open line if you prop the brake pedal in the down position with a stick or pry bar.
It will have to be changed anyway. Have you seen the color of it !?
Can you pulse width modulate PWM the single l.e.d at 50% for side marker and full pulse for indicator,
Been thinking of this: "sell" it as best offer to the shop on ebay? Include their money in the rebuild cost so the get it back. Ebay shipping is lower cost than what you paid.
wonder if two leds in opposing directions wasn't the simple solution
Hey, I don’t know if this is helpful, but there’s a TH-cam channel called Classic Octane - a guy in Austin who rebuilds motorcycles. He uses a black box to program all the lighting functions. Can’t remember the name of it but it worked great…
👍😎👍
I live in the state of PA and we are not aloud to modify a vehicles lights or upgrade to LEDs. It will not pass inspection
How ridiculous !
Motogadget M- unit…
Don't think I want a GMC motorhome anymore
Keep in mind this thing was designed 50 years ago, and manufactured 43 years ago. This is like a classic Mustang or Corvette that you can sleep in. It's a muscle car that happens to be a motor home. It's not a competitor to today's technology. That's why I'm restomodding it.
@@IndustriousPursuits
And it still will look way better than the modern ones.
A good design never gets old. Look at the Porsche 911, designed over 60 years ago ! It evolved but the shape is still the same.
