SILVER Star
2000 LC 100. Dual batteries (27 Interstate & 31 Optima Yellow Top) with a RedArc BCDC1250D. The accessories (firdge/winch/offroad lights/EcoFlow house battery) all run off of the Optima. So the starter battery really is just a starter battery.
I had to slam on the brakes yesterday and the battery light cam on along with the ABS/Atrac lights. TorquePro showed voltage in the 8-9V range and it fluctuated from idle to running. I connected the starter battery to the Optima and back-flowed the EcoFlow to the Optima to make it home.
It had an older battery, so I put in a new Interstate. The voltage now is 11V (TorquePro) while running and at idle. No real fluctuation. The battery light is still on, all others are off. The dash gauge corresponds to the OBD reading. No OBD Codes.
So my questions are 1) Alternator or something else? 2) Assuming that it's the alternator, I would rather a higher amperage replacement, so what's out there that is proven in our trucks?
