Note the Black cable(#1) connected to the LH terminal. More of that in a bit...

Next item to the right is the House battery disconnect switch.
Note the smaller red wire connecting the RH of the combiner solenoid to the disconnect switch..
Is that too small gauge?

Note the HUGE(5/16 or 3/4 dia) Red cable on the RH side... that is the one I pulled and rerouted and takes House battery power to the relay/solenoid in the driver firewall.
the shutoff switch for the house batteries normally only shuts off the power to the fuse panel of the coach. Why they wired that fat red wire to the right terminal is beyond me?
May be someone with more advance electrical knowledge can chime in and justify the much thinner wire on the left to be sufficient, since it is so short???

Thick Black cable with ribbed grey cover pointing UP went to starter lug(the cable that was melted).
Black cable with ribbed grey cover pointing DOWN is MAIN ALTERNATOR feed/power/charge cable.
Black cable behind this one pointing down, is main power feed for HWH Leveler pump.

Note, the Alternator power cable is pretty beefy..
In this pic I am comparing a 10 Gauge cable to the alternator feed/power cable!
!
According to the alt charge cable, you must have a beefy alternator or you could easily add one.
The only issue I see is that only your Motor battery gets charged via the left terminal.
A very easy fix for that would be to install an Isolator just below that solenoid with the beefy alt cable going to the center of the new Isolator and one side feeding the motor bat and the other the coach batteries. (there may have been one originally).
If you do add an Isolator later, make sure it matches or exceeds the amps of your alternator.
After that you would actually have a very strong setup and could leave everything as is.

Peter,
I did not get to testing yesterday as I still need to install the fuel pressure regulator between the hard line and carb...
I am seeing 8 or 9 psi with the rear electric pump, and the carb fuel bowl needle was being overwhelmed.
I am also going to install the Zemco computer fuel flow counter there.
Also, I had missed replacing the rubber section of pipe between the mech fuel pump and return line... And Brad was correct, it is 1/4"... Tried 5/16 and it was too big! . Which is super weird because all the other return line is 5/16.
Still working on the vacuum lines... Realized I had missed the feed for the entrance step, so that is fixed now. Just a couple of smog items to add and replumb the lines to the cruise and that funny little canister... And HVAC.

I was pleased to see my alternator wire is beefy... But it was not tight on the terminal so I dealt with that! Maybe my alternator is a good one... It looks newer, but is still externally regulated. I looked up the regulator part # and its an HD item.
I too, was having voltage fluctuations at the dash meter, so I will keep an eye on it now.
I didn't think about where the house electrical feed is... I will look at that today!
Once I have the motorhome moved I will work on improvements.

I did mount the smog pump diverter valve yesterday... I tested it, and while the diaphragm does not hold vacuum, it does move the plunger... I am wondering if that is correct... It's only supposed to divert air under deceleration... Which is high vacuum... Maybe it is designed to bleed down..

Two words, voltage drop. Small wires can carry high current for very short distances but if you're running from that switch clear over to where the DC converter is then you want a heavier wire so you don't have a large voltage drop. That large red wire may be slightly over sized but I'd rather have that situation than the alternative.

Simply put, as voltage drops then current goes up which can cause wires to get hot and melt.

So, do you think that little jumper cable is enough Brad?

Keyair I have a solenoid fastened to the top of the Hydraulic Pump for the levelers. It is fastened to a strap that is around the pump/tank assembly. This assembly is located in the front of the Motorhome between the bumper and the radiator. Is that the same solenoid that is located on your firewall. If that is the case you could move it to the pump location and add an isolator.

I will take some pics today and confirm my setup.

If the little jumper is #6 or possibly #8 it should be ok.

What is the charging rate of your DC converter?

I'm 95% certain my old 310 has the same size wire as well.

If I was a betting man I would bet it's the original switch installed by Airstream used to energize the solenoid that ties the starting and coach batteries together. I think you mentioned you had a switch mounted elsewhere that does the same thing. More than likely some PO installed the other switch an relocated the wires from the original switch in the glove box to the new switch.

All the way with Brad on this one. My 345 had that toggle switch in the glove box

As did my old 310 and the 86 345 that I dismantled.

My 310 is ignition switch driven, just like Steve's front solenoid for the levelers

Hey guys! Its been a while since I've been on here but I was about to post myself and I came across this. I just bought a 1987 290 with a custom Kendon trailer. I bought a smart car as well! Its the ideal combo for me. If I can figure out how to post a pic I will. The trailer is easy to move around by hand and the smart car is less than 2,000 pounds. Not the V8 like my other vehicles but it does the job.
