The battery charger is for charging batteries only and not for testing charging systems on cars. If I have this wrong then I am sorry but please explain in more detail. Regards, Kevin.

Hey, it's confusing to me too or I wouldn't be asking questions. LOL This is something that I've just noticed for the first time and it got me wondering.

Yes, I sometimes leave the BT connected when I crank it, and run it a while in place. Why should I not do that? I sometimes disconnect it and run it in place as well. It doesn't seem to hurt anything to leave it connected while cranking/running.

Just as a check, I will disconnect the BT and crank and run it and see if that makes any difference. I will report further after the test. No time to do that now.
