Had/have an issue that set of new batteries didnt seem to address.
So now I'm thinking alt going out? Question is , so they just quit or will they slowly fade in charging the batts? New set today started with 14v at speed. Drove the new set for 3 1/2 hours. Get to first stop come back out and voltmeter struggled to hit 13 v and fluctuated the rest of the day. Previous with old batts and including today with the new ones in, after about 20 30 min the power to cab cuts out. Bunk heater causes the same ,will run but no other power available. I use Cpap and I'd rather be rested and safer but still stay warm too.
How long drive time til batts are fully charged after install and the above question on how alts go out.
Thanks in advance. Company driver trying to learn from you helpful folks.
