why does my unit make a continious loud buzz noise while driving. i have put new trogian batteries about a year. Won’t keep a complete charge after charging.
After driving for a little check voltage at each battery with a volt meter set at D.C. Voltage. Fully charged 6 volt battery will be 6.3v now after some use the voltage will be a little lower, but what we’re looking for is a variance. If you have 5 batteries with 6.2 volts and 1 with 4.1 volts then the one battery would be the problem…. On the buzzing sound while driving… where is it coming from? Motor? Batteries?
