over the last couple of years Ive fixed a few things that were sort of low voltage dc.
examples
two makita 9.6 volt drills
they would not work until i completely cleaned the contacts that go against the battery in their entirity..
i tried just cleaning the point of contact ..no go....had to clean the whole strip...a clear path from one end to the other
torch 3 volt with spring at the back end
only worked when i cleaned off corrosion off the whole spring ..not just the bits in contact...either end...again, i had to have a clear path from one end to the other
Ive read posts on the web that say only high voltage or high tension goes on the surface ...
but my recent exploits tell me the opposite....and that low volt dc travels on the surface .
BTW ..when i say corrosion ..i mean plating oxidation
all the best.markj
