1997 Ez-Go TXT Series

[jkg2003]

2 weeks ago I burned up my stock controller and so while the cart was down, I decided to upgrade my components.

Alltrax NPX 4844 controller
4 Gauge welding cable
200 amp soleniod
HD FNR switch

Now my issue is that after I charged the system, I ran the cart fine for about 5-10 minutes and when I went to go the soleniod just clicked and didnt move, the controller didnt light up either. Pushed the cart in the shop, charged it over night, it only charger 1.5 hours and the next morning the cart ran fine again and I drove it down the drive way, about 1/3 mile and let it sit for about 10 mins talking to someone and went to drive away, again jus a click out of my soleniod. My lights are working just fine...very bright still.
Before the first controller went out, the cart would run 1-1.5 hours no problem, with plenty of juice left.

Any suggestions??
