[urq] Re: Hot Start/Thermal wrap

[dd]

I had a hot-start problem on my '83 (last 3 digit of vin 530) that I 
fought for a very long time before
I finally figured out the problem. 

There is a spade lug connector near the turbo that is in the middle 
circuit from the key switch to the starter solenoid.   Indeed,
a stupid place to put the connection - near the turbo!  When the 
connection gets hot enough the female
side of the connection relaxes just enough to open the circuit.   As I 
recall I rerouted the wiring away from the
turbo and replaced the connectors - no more hot start problem.  

Now, if I could just figure out a way to may to make the damn electric 
windows go up and down at a decent pace I wouldn't be
thinking about selling the beast.
