2007 ruff and tuff / ez go elec problem

[Rpeugh]

I'm a new user with a 2007 ruff and tuff, 48 v cart. Fwd & reverse switch is on dash. I've been told ez go parts work on ruff n tuff carts. The cart has good batteries and clean term. It turns on and shows full charge on gauge. After put in forward or reverse, and press the accelerator it moves maybe 1/4 inch, suddenly stops, and all lights/gauges turn off for a few seconds. When they come back, it will do the same thing. Any ideas?

to me this sounds like a loose connection. it has power when you turn it on, which a loose connection can do. but when power or load is applied the connection isnt strong enough to carry that . double check all battery posts , solenoids, and switches ..
