I have a 2012 210SX - Voltage Alarm on Starboard engine when flushing (not Port), 16.7-16.8V. Could I need to replace my stator or something else?
Backstory: During our last outing, I received a voltage alarm during our cruise back from dinner. I acknowledged the alarm, and continued on our way back to the dock (~15 min cruise). I had figured it was time to swap out the batteries, as they are approx 3.5 years old. I have replaced one of the batteries with a new AGM battery, and also tested both to of the older batteries. They seem to charge w/o issue, and hold a charge >12.6V after sitting in the garage for over a week.
Today, I was doing some work on the boat and wanted to flush both engines. I flushed the port engine for 10 mins, no issue. Fired up the starboard engine, and within ~2 mins the battery alarm was going off. In my head, I said, well maybe its time for a 2nd new battery; then I switched to battery “B”, the new AGM battery, and the alarm went off. About 5-6 mins later the alarm returned, this time I decided to cycle through the gauge read outs, and I saw that the voltage was reading 16.7-16.8V. After a few minutes it returned to reading 14.6-14.8V range. Also to note, I have a simple Perko A/B charger, A is my older battery, and B is the new AGM cell.
What could be causing this? I have the service manual, and there isn’t much info regarding the Charging System/Stator, other then checking if with a 3 pin harness, that I do not have. I can’t even tell from the diagrams, where the stator is located... (not sure why my shop manual has the red water mark, maybe it was a bootleg version I purchased?)
Just wondering if I risk damage by seeing if this continues to alert when I am out on the water, or if there is other action I need to take now.
Thanks!
