(ET) Hot frame (post 2)

You make a good point, Chris, about my frame not being isolated from the 
batteries. Since my blown R1 trouble, caused by its touching the frame, I 
measured the voltage on the frame relative to battery ground. I got +37.2 
volts 
(with the key switch off), which is exactly pack voltage. I know the frame 
floated on measurements prior to my R1 trouble. So something changed. My 
headlight circuit is suspicous, but its a 12 volt circuit. How can I find 
the 
fault other than by disconnecting one wire at a time? 
Thanks, Bill
