Classic ZF trouble..?? 87FC35

[Tom Warner]

I would strongly urge you to NOT do this unless you have the diagrams
for the dash and chassis for your particular coach. Lifting the dash
can get you into more trouble then you started with if you start
straining wires.

Troubleshooting these problems is easy if you understand how the
circuits work. I sent Alan a diagram I had that traces the starting
circuit both to the starter and the fuel solenoid so that it is easy
to trace this problem pin by pin.
