My neighbor has an older 36v series E-Z-GO TXT that wasn't running right. That problem was just a couple loose connections. The problem now is his Powerwise battery charger doesn't work properly and I can't find the problem. It only charges at 5 amps and I've checked everything that I know or can find. Everything seems fine and I hate to start throwing parts at it. Relay clicks [ jumping it doesn't help], diodes check good, continuity thru all wires/connections, capacitor reading is 1.7.
