Default Wiring question

I'm working on fixing up a '92 EZGO Marathon 36 volt cart. It had the remains of an old Controller Varistor, but I can't figure out what it connects to. Can anyone help me out with where it goes?

Can you post a pic of the "Controller Varistor" you are referencing? Been a while since I worked on an electric Marathon, But I do not recall and can't picture the part you are referencing.

Older carts had a bank of resistors to control speed, but those did not have controllers.

Yup, see the attached pics. One is a stock photo of the resistor, the other is my cart (excuse the rust and the spaghetti wiring - that's all being replaced). The resistor is the solid yellow circle at the arrow. It looks like one side is connected to the controller - I just don't know the proper attachment.

Pretty sure that is the resistor that connects to the main lugs of the solenoid to precharge the controller so the solenoid doesn’t spike when closed.

Makes sense. So you're saying the main lugs - again using a stock photo, do you mean the two lugs with the arrows?

Oh, by the way - cleaned up the cart a bit - no Paws on it - for now... :)

No it would go on the solenoid main lugs.

Well disregard my last message.. I was incorrect. That is a MOV and does go across the lugs you showed. https://www.buggiesgonewild.com/showthread.php?t=136177

Thanks for the update. I picked this up from a legacy post:

"Factory install was B+ to B- on the stock Curtis 1204."
