Ez go dcs smoking controller

[PTL]

Got a 1996 dcs cart that was layed up over a year, batteries were trash so I used a battery jump pack to test the motor to see if it ran, motor was good, bought new batteries and tested vart. All was good for about 100 yards then I started to smell electronics burning, flipped run/tow switch to tow and pushed back to house. Blueish smoke was coming from the controller.

Any idea to what caused this? When I put the jump pack to check the motor did I back feed the system and cause something in controller to fail?

It's possible you damaged it. However the only time I have jumped batteries was with another cart, but that was just to get the voltage up enough to turn the charger on. You mentioned the cart was left sitting for over a year, but when you said bluish smoke it sounds like the burning component made that color. You said you installed new batteries so the controller had an issue to begin with. I have my doubts you caused the controller to burn up. Long as you didn't pump too much that the cart could handle, I don't think jumping the batteries would destroy the controller

@yamahaguy97-thanks for feedback, at the time I used a jump pack I didn't have any batteries in the cart and I connected straight to the motor terminals

DCS controllers have a fatal flaw-no low voltage protection- running a controller on 12v can cause the magic smoke to come out-no magic smoke often means it is time for a new controller...see scottyB at cartsunlimited for a new alltrax controller that has low volt protection built in....

update - took controller off cart and board was fried, replacing it with a alltrax 400a

Second-hand smoke can kill.
