My NASA BM1 often gives crazy amps readings of over 100A when the battery is fully charged and there is no load.
I traced this to a poor contact on the white lead.
Problem is that I simply cannot get the contact to be reliable. I tried smearing some grease over the contact and this worked for a short while before returning to its crazy readout again. I have tried soldering the lead to the block, but I can't get the solder to stick to the brass, no matter how much cleaning or soldering paste I use. I have also given it a really good clean with contact cleaner fluid, but this will not give a good connection either.
Is it worth trying special conductive grease? If so what is best - copper grease? Or one of the special battery terminal greases that are available on Amazon?
Or any other suggestions?
