Re: (ET) Totally dead E20, thoughts?

The dash lamp is a 14V nominal automotive bulb. You would have to watch it very carefully, with sunglasses on, if a 36V fault were present. <G>

Chris,
Are the seat bolts shorting to the battery posts??
Other wise I would build a ground detector, like the ones used on crane
rails. It just takes two 36 volt light bulbs, like the one on the dash
light.

use the following diagram

     -----------------------------------------------
     | +         -                     -        -   |
     |    B6        B4                              |
rear |       -         +           B2       B1      |  front
     | +         -                                  |
     |    B5        B3                              |
     |       -         +         +        +         |
      ----------------------------------------------


B5+, B6- leads to zero volts when measured to frame. B6+ has 6 volts,
B5- has -6 volts.

Weird, hm? I'm going to sit down this weekend and have a long look thru
it.

Chris
