Re: (ET) sparks!

Thon, I was surprised to see your post because I had the same experience 
plus some excitement here with my E-12 tonight!. While removing the nuts 
and bolts to get the right side panel off, I had to partially remove the 
charger cage and accidentally scraped it (actually the resistors strips) 
on the chassis. Even though the main disconnect and the key were off,  
it took off in reverse and I had to jump on and ride it and figure out 
how to stop it. Fortunately it didn't run into anything. When I jiggled 
the charger cage it stopped and I saw that the R1 strap was burnt in 
two. I've know for a long time that I have a ground fault but haven't 
tried real hard to fix it. The charger cage has had 13 volts on it for 
some time and I use a piece of wood to insulate the mounting screw. 
Someone said a likely place for the ground fault is in the lift motor. 
I've got a replacement for the R1 resistor, so I'll see if that fixes it 
tomorrow. Our problems are similar. I would say your charger cage has a 
voltage on it and if its not insulated from the frame, the frame is hot 
also. Good luck fixing it.
