[Shotimes] SHO is down... hope i didn't f' it up too bad...

[Leigh Smith]

Check for loose cable connections everywhere. Then test for starter 
current draw on-car with an amp meter. I think mine drew 80 amps or so. 
Test the battery wires for voltage drop on-car and also for shorts. (My 
6 foot long positive on my 89 shorted out against the motor mount and 
almost burned up the car.) Also test the battery and starter off car at 
a shop if needed. One of the above should find it.
