I appriciate all the advice you given, it is truly appriciated. I am not an electrician nor a trained forklift machanic. I apply what little electrical knowlegde taught to me when i workded for an A/C company. This unit if the first one to really stump me. I figure i've been able to diagnose or repair at least 95% of problems encountered with our 17 forklifts. Major repairs i leave for crown. Now i will go apply what you wrote and see what i find, thanks again.
