Unless there is a current issue..... don't mess with it.

Standard test equipment (VOM and Megger) can isolate problems if you have one.

If you're that concerned, pull new ones through to the gear disconnect plugs.

I'm somewhat lost??? Are you having problems with a gear?

We don't go looking for issues, we fix the ones that show up. I'm not into theory or "possibilities". It's either broke or not. We've reached the end of this topic.
