i just replaced my starter batteries because of a weird voltage, but with the new batteries, the weird voltage did not go away.
my batteries were fine when i installed them.
2 days later (today) i started the bus for the first ime on these batteries and looked at the battery meter. all looked strong. 13+v, the alt was charging. looked good. it ran like that for 15 minutes.
i [pulled out on to the road and was cruising to an rv park, and 5 minutes down the road, i looked up again and my volts were 10.3 with the alarm going off.
at first i thought maybe it was the brake circuit, but that has little effect on the short erratic voltage.
the culprit that seems to trigger the short is moving the trans lever from neutral to drive. in neutral, the volts are stable. when i move to "D" the 10.3 volt and the battery alarm go off.
not sure where to look...... virtually an at545 trans.... really the big brother at1545 but there are no difference to the electric portion (does it even have an electric part?).
any tips appreciated
