yes i tested switch it works i think the big problem is that the windshield was broke and the dash was apart so water got all over the contactor and board i got the charger to work we got 72 volts coming out of the round white thing to the right of the contactor not sure what that is called

Sounds like some sort of parking brake sensor issue. All connections secure/clean? When you have the key on and release the brake can you hear an audible click? I sometimes have to drop mine with a little force to make the code clear.

Here is a handy list of codes for you… [- Complete List Gem Error Codes -](http://www.electricforum.com/cars/neighborhood-electric-vehicles-hev/2486-complete-list-gem-error-codes.html)

Check the reed switch by the brake lever. You should hear a faint click when applying or releasing the brake. If not, adjust the switch so that it clicks about one inch from the bottom released position.
