I plug my Noco (10amp/bank)in after each time I go fishing. It’s usually green within 2 hours on both banks, and I plug it in the night before I go fishing and unplug it when I leave for the ramp.
Last night, the last time I checked, both lights were green. I get to the ramp this morning and my trim is really slow...hmmm. I put her in the water and Nada! I carry a lithium ion little jumper with me so I jumped it and the motor started fine.
My voltmeter read around 14 when I was under throttle but after a 15 min run around the lake I turned the boat off and tried to crank her back up, nada.
Needless to say I fished within sight of the ramp and jumped it again to leave. On the run back to the ramp my boat (‘06 Triton SP185, ‘06 Etec 90) kept doing weird stuff. The tach kept jumping around, the 4 lights and beeps that happen when you turn the key on kept going off like I just turned the key on.
I got home and the volt meter read 10.24volts. Yeah that’s bad!
I’m really hoping the battery is just bad and nothing else. Last week the battery was fine when I used the boat. We did get into the 30’s twice this week which is odd for Florida, but I saw no gradual decline in the battery, just dead.
Im headed to get another battery, just wondering if you guys have had a bad battery cause your gauges to go wacky?
Thanks for any opinions. Chris.
