Red face 1987 Electric Ezgo runs but sparks when throttle is pressed

Hi guys and gals! Ezgo Electric Newbie here..... we bought an older 1987 Ezgo Electric Marathon cart for CHEAP and have been doing what we can to get it back to par so we can haul it to the campground. QUESTION IS... we had the seat off checking connections and there is a spark that happens when you press down on the throttle/accelerator pedal. It appears to be almost like a striking spark or arch against a wheel that looks like circles are on it (sorry, I don't know the part). It clicks and runs as intended BUT is there "suppose" to be a visual spark on these older models or is there a buildup or poor connection that we need to address? There are no loose wires or anything obvious that is touching. Sorry just not really sure what we are dealing with. First time owner probz

Talking about the forward reverse lever sparking? Wha model model cart?
spark indicates a bad or lose connection. Not a good thing.
Spark+ batteries = chanse for explosion.

1987 Ezgo Marathon Electric 36 volt. I have been told it’s the Potentiometer or swiper? But yes it’s down by the solenoid the wheel to the left

It is the swiper. Both parts can be found new on ebay fairly cheap

The part you are referring to is called a Speed switch board with contacts OEM #18741-G1 (for 1982-93 EZ GO), The *swiper* you see moving is called the Movable Contact OEM #17504-G2...They do spark a little when they are either worn down/wires going from them are worn or loose/or if your resistor coils are not all intact. They are all available online as binder49 says.

Try looking at the micro switch just above those round connections.
I had one doing the same thing and the wheel on the micro switch was
Bent and allowed the contacts on the throttle to meet to early and created
A large spark.

Best of luck

I guess actually it allowed the solenoid to closed too soon before the contacts
On the throttle we’re making good enough connection
Anyway it worked so........peace!!!!
