Do we have a part # or equivalent to the 12/24 battery rectifier?

Do we have a part # or equivalent to the 12/24 battery rectifier? I believe mine is starting to fail. Thanks!

The polarity box under the spare tire? You can bypass it. What makes you think its going bad? The main grounds go bad I always add a new big ground from the batts negative to a sanded spot on the main frame rail.

Yes, the polarity box. I am getting current leakage, evident with lights staying on after turned off, but dim. Good idea about the grounding.

Bad ground and current finds the next best path thru something else.

What truck is this on(A0 or A1)? What lights are staying on? What are you turning off?

A0. Auxiliary LED lights, which are diodes essentially. Could be part of the issue too.
