Hi Great site love it, Where can you purchase the copper contacts and is there a technical name for them didn’t know that I could have repaired much craftsman 82040 meter by piecing out the harbor freight free meterand using the contacts which were worn out and non repairable and started to hand make them and then ran across this site. Thanks for the tutorial and being part of the solution as i am an automotive parts rebuilder keeping land fills few of good core since 1988.
