when I got my m1009 in oct '09 the volt meter stayed about 3/4 into the green, well i had to rebuild the starter but right before i ran the batteries low by startin it till the starter died, got it rebuilt and put on , 2 weeks later the pass alt. starts laggin and the volts meter reads right at the ywellow and green line, so i had the pass alt rebuilt, put it back on but the volts are still at the green/yellow line, where does the volt meter need to be on a normal m1009?
