I have an aluminium battery box with a row of lithium ion cells in it.
I dropped a small bolt which made contact between a busbar and the aluminium box - There was a spark and some soot -
So I did a test with the meter -
I hold the prongs, one on the box and one on a terminal (or busbar) a spike in voltage for a split second of sometimes 1 volt is shown - then it drops down to .089 volts
Is this normal? is it bad?
I tested for resistance and always get the OL
