And with this same configuration, what is your reading on Pin #6 at the controller now?

I decided to remove the controller and open it up, I could tell something was wrong from the smell alone. I removed the cover and you can see from the pic something is damaged. So I know I now need a replacement controller but do you have any idea what would cause this? I don't want to install the replacement and have it fry if there an another issue.

It could virtually be anything that caused it. Age, component failure, spark, etc. I have seen filter capacitors go, FET's etc. etc. That is why I am not a big proponent of "rebuilt" controllers. When they are inspected, it is only the failed components that are replaced. All others are still OLD.

I am assuming that is your factory Curtis. Time to upgrade to an Alltrax. You can get a 300a that is a direct replacement or upgrade to a 400a or 500a that will require cables, contactor, etc. but prepare you for more down the road in regards to tires, motor, etc.
Here are the Alltrax Sepex (IQ) controllers for your cart you can look at. https://www.revolutiongolfcars.com/a...ct-controllers
