89 E_Z Go Marathon Controller

This cart has a set of headlights which are grounded to the metal body. One negative battery post is also grounded to the metal body. The lights work fine, but I thought grounding to the frame was a no-no. Am I correct and if so, why?

The lights or the batteries should not be grounded to any metal. What can happen is the full pack voltage can back feed through the ground and blow any accessories that aren't 36 volt.

Frame grounds are not allowed on sparky carts because all sorts of stray voltage can be running around the chassis. The fact that your cart is getting away with it is unusual, and that situation MAY change, especially if ANY corrosion occurs in your frame grounds.
