if you google "general electric ev100" you can get most of the information you need to work on the system itself.
Things such as this: hxxp://w w w.fsip.biz/Documents/EV100LX%20Instructions%20with%20EV200%20Supplement.pdf

of course correct the x's in the beginning and remove the spaces between the w's to make the link workable but that is just one doc i found on the EV100LX with EV200 supplement. There were other links as well. Theres plenty of GE EV information out there if u look for it. Just do your research, dont be lazy ;oP
