Default Battery Issue?

Today while running out 35-miles I had the battery switch set to both being that the boat had been sitting for nearly 2-months again since last being used. Once out I switched to battery #1, I noticed when I adjusted my trim tabs, or tilted the motor up or down it would kick my chartplotter and radio off for just a second. Getting back to the dock I restarted the boat on just #1 and it seemed to have a low battery and had a hard time cranking. With both batteries selected no problems.

I figure it is time to replace battery #1.

It may be time to replace that battery, and it's certainly time to check your electrical connections, starting from the battery, and working your way to the load.

it would be advantageous and prudent to cheek your equipment regularly at the dock instead of "discovering" a problem while underway.....makes for a much nicer afternoon on the water - voltage and load tests are free at the auto parts store...

it could be the battery wasn't properly charged prior to using. If a battery is heavily loaded, even while charging not enough juice goes into the battery. Remember power going into the battery must be greater than power going out to the many devices connected to the battery for it to build up charge.

There could be several problems. Most likely battery one is weak or the connections going to battery one are failing. I would remove battery one and have it tested, NAPA there in Manteo will test them, and while you have it out clean the terminals and post well with a stiff wire brush. Also check the wiring terminal ends. Once you either replace or re-install battery one apply some anti-corrosion spray to the terminals and post. You can also check the connections inside the battery switch.
