I had a low voltage alarm go off again. I had the same problem since I've had the boat. I thought it was caused by the stock battery (Interstate grp 27) not being able to handle the load. So during deer season, and since I wasn't running the boat, I put in a Sears PM-1 grp 31. I used the marine battery post connections like Don suggests.
That at brings me to today. The same alarm went off. My SmartCraft gauge was reading 11.2/11.3 volts on the STBD battery. It was reading that same voltage all day but didn't sound the alarm til 3:00 this afternoon.
So, I need some advise on what could be causing this now that I've excluded the battery. The boat and motor is still under warranty if there's a problem but this seems like something simple. Just can't put my finger on it.
Mr. Weed please chime in when you can please sir.
