Default Took apart dashboard - now won't start!

Sometimes I get myself into more trouble than it's worth!

'83 FC. Speedometer hasn't worked for over a year. We're at a nice campground near Palm Springs - so taking apart the speedometer came up on the list. Disassembled the dashboard (at least the 4th time) and got the speedometer apart, found a styrofoam peanut in it! Possibly the problem. Got the speedometer back in the dashboard and decided to check. Turned ignition to on and noticed my digital Amp gauge went to 35 Amp load. Shut it back off. Decided to see if I could start it - it did but soon there was smoke from the wad of wires under the dashboard, So I shut it off. By following the smoke, found a bad connection in a canon connector. Wired around it. Now no high amp draw, but no start. Nothing when I turn the key to start. There was voltage at the wire at the cannon connector when I repaired it, now there is none (yes there was a moment when a bare wire brushed a ground - sparks).

Picture 3

Traced the wire (Yellow) I repaired one way and am pretty sure it is going to the starter switch. I've never taken in out before - and am wondering what the trick is?

Pictures 1 and 2 (sorry they're upside down)

Traced the wire the other way to another canon connector that is really really buried. No idea how to get it out and can't see where the wire is going from there.

Pictures 4 and 5.

So, I'm really questioning my decision to try to fix the speedometer... But at this point I have to get the bus running again. Any help would be greatly appreciated!

Here are two 83 FC “Start circuit” drawings from Wanderlodge that I posted back in 2011 – they may help you locate the problem:

Do you our anyone else know what the "body hot" is in the diagrams? Is it one of the 12v fuse panels?

I wish I could help you but for this you don't want my help. I don't suppose I have to say this, but I will. If you are on the road, DON'Twork on the bus for any reason other that to get it moving and on the road.!!!! If it s running and moving you down the road, leave it alone!!! Wait until you get it home and then go for it. Hopefully you will get this one under control

An 83 FC owner would be a better source but... On an 83 FC, I "think" the Body hot in question should be on a terminal strip way up high in the front left bay (the outside compartment that's below the driver's side window) - If you're lucky, the terminals will be marked.

The Body Hot is often the first or second terminal from the left end of that terminal strip and usually it has several wires on it - probably at least one of the wires will be 6 GA Red wire.

Jim,

You are so right! I am questioning my choice to work on this now.

There is one mitigating circumstance though - this is home. We are full time so there really isn't the "safe" time to work on it where if it stops there is someplace else where we are living.

I probably should have waited until we were back in Vermont where I have more resources and a diesel mechanic 45 miles away who likes to work on Wanderlodges.

Part of my staying sane traveling the country in a 34 year old, highly complex, over engineered machine is I consider this my hobby. My hobby is with me everywhere, and when things need fixing it is a learning opportunity.

Some of the lessons are harder than others though.

Wish me luck!

A diesel mechanic is not going to be any help here.
But,you can run a new wire to the fuel solenoid and put a switch on it,then all you need to do is run a wire to the starter,and it will run.

Ok Craig, I lost track of who is full-timing and who isn't. Yeah you do have different circumstances, for sure. Best of luck on getting it going again.

AT switch?

Dumb mistake but lots of folks have made it!

Anything in the dash is a daunting project. I am replacing a few failed gauge bulbs and now the dimmer switch won't work. Stays on HIGH. I am sure I have disconnected a wire somewhere. But this keeps me out of trouble!

check the A/T switch. The main wire to the ignition switch [RED] on my 82 got a hot spot in it and started failing years ago, the first 6" from switch. to remove switch, hold key ring from moving, up down all around. reach up from under the panel push up on switch turn clock wise . [If you are trying to remove switch.] P.S. i FORGOT,You must be upside down down in drivers seat with feet on the ceiling for tracktion, for ignition removal
