Alright, update Put in my old R/R Battery now charges BUT when doing this it reads -12v yes negative what does this mean
For one I would say that you are in a VOLTS measuring range, not AMPS. Secondly the POSITIVE terminal of the meter was not connected to the positive terminal of the battery, therefore a negative reading. Other than that, it is all a bit meaningless...
my bike is amazing at running against all odds. its not been used to nearly a year, it has no exhaust headers on, it has water in the fuel, and the battery is flat. it bumped first time and ran ok (if very loud) lol.
