Today was my first time out in the boat in the last 6 months.
After riding around for 10-15 the dash lit up with low voltage warnings. The voltmeter was reading at 11.3ish at that moment. so I picked up the RPMs to let the alternator do its thing. Within 10 mins the warnings had gone off and the voltmeter was back at 13.0! But every time I let the RPMs drop or turned on the stereo, ballast, etc the voltmeter would plummet.. This is a bit frustrating because I had the batteries on my CTEK 7002 all winter.
I went to interstate batteries to have them check the batts. All checked out okay. A little low on water in a few cell. The cranking battery was "marginal" upon checking a few of the cells water. So I bought a new one.
Does this sound like a system issue or a battery issue to you guys? Like I said the alternator seemed to be doing its job just fine by increasing to voltmeter, but I'm a dentist no electrician. So what do I know.
I also bought the cigarette lighter adapter for the CTEK can I just plug this in and forget. I have the two batteries in series, so I didn't know if this will work. I usually unplug the batts and charge them individually.
TIA
