Losing voltage???? What could be this then...

Ur not loosing voltage , it's because at idle the alt outs out less than at cruising speed ( around 2k rpm), every alt has an idle rating and a higher ROM rating . Its normal, I'd suggest charging the batteries overnight on 5a or so bc if they were run low when the alt wasn't working u could be less than 100* voltage. Jut my two cents tho.
