Clean 12v switched source that is hot cranking and running

I have not experienced this with the Holley I ran the old old Holley "pro-jection", the slightly newer Commander 950, and finally, the Holley HP

Maybe it is the G3 Hemi swaps that I have heard of having an issue? Not sure, just sticks in my head that it can be a problem in some cases.

At the same time, I wonder sometimes at the things that stick in my head so maybe it is an urban myth?

Who knows, just tossing it out in case it somehow helps the guy.
