Here’s one. When engine is started I get the low voltage alarm ( reading 12.4 volts) which continues at low speed idling through no wake zones.. When I get to about 1500 rpm,voltage jumps to 13.8-14 which is normal. Voltage stays normal even when go back down to idling. But, once engine is off, and restarted low voltage alarm comes up again and cycle repeats. Not sure why this happening. I think I’m ok but wondering if there is issue with low voltage when idling. Wondering if engine battery issue. Marine service guy says don’t worry about this.
Thanks in advance.
