Thanks so much for the help. I don't see a card under the control levers ? I googled EV100 , other than 1 contactor , the one I jump , it's not the same as my forklift. I wish I could post a pic. Maybe email me and I'll send you a pic of what set up my lift has. [email address removed]
I suspect one part , a pic would go along way

The lift was working fine, we stopped for lunch , after lunch nothing? It had worked fine before , even with the batteries at a lower voltage. I do power it with 6 huge 6 volt golf cart batteries.

Thanks Again !
Daniel
