I have an old MH20GT which unfortunately won’t turn on when the battery tube is tightened past ‘99%’. So completely tightening, or tightening to what would be considered a normal amount won’t allow it to turn on. It’s become a very fine art tightening it the right amount to enable powering on.
Does anyone know what the issue could be or how I can troubleshoot?
For cleaning? Scuff with fine-grit, wipe with an alcohol pad like you can get at CVS or whatnot. Or just IPA on a tissue.
Me personally, I don’t bother with loctite and just snug up any rings with ring-pullers (“snap-ring pliers”). I don’t like anything that might “pollute” the threads, but you decide if you want it to be semi-permanent or not.
