Starting Problems

[amweath]

Quite often I am unable to srart my coach ('85 PT36) from the front
position. When that happens I have been able to start from the rear
position.

The first thing I suspected was the rear toggle switch. That has been
eliminated as has the anti theft switch on the dash. If I disconnect
the wires from the a/t switch I can see 12v coming from the front
ignition sw. when turned to the 'start' postion. I can also see the
ground coming from the starter ckt. solenoid on the other wire. So it
appears I have good circuitry.

This problem seems to happen when the batt. voltage is below 12v.
If I start the generator, with the increase in voltage I can start it
normally from ther front.

Could I have a weak solenoid? Where is this solennoid located?

Located in the 'files' section is a diagram of the start circuit for
my coach. This is what I've been working from.

Anyone have any thoights on this problem.

I don't know if this will help or not.
Recently, my starter was acting up(or so I thought). The coach finally went dead while starting it. My manual battery master switch was failing and finally burned out. I replaced it and cleaned all the main grounds around the engine. The starter really spins the engine now. It started fine last weekend without preheat at 29 degrees. I think my solenoid is on the right side of the engine up about half way in the engine bay.
