Hello, my name is***** will assist you.

If the gauge is reading low voltage, this means that, although the battery may be good, the engine is not getting it fully. This could be a bad cable going to the starter or the block, a corroded connection going to the ECU, or loose cables/ dirty connections at the battery.
