A friendly reminder that now is a great time to inspect your safety gear. I checked my life jackets, throw cushion, made sure my flares were good for the next season, etc. I also replaced my house and starting batteries as they were 6yo already (how time flies) and they were only holding 12.5v fully charged. I still have an electrical gremlin to figure out as my new batteries read 12.9 on the voltmeter and the engine gauge, but only 12.0 on the fishfinder. I've had this gremlin for a year and have my suspicions, but ran out of daylight to track it down.

I always show a slight voltage drop on the gps/fishfinder, It improved when I ran a new 8 gauge wire from the house battery to the console.

Good advice again! I normally use the hour meter to schedule most maintenance and this time of year to check out and fix or repair the smaller stuff and throw a coat of wax on the boats. I had a bug in one side of my trailer lights that I traced and repaired yesterday. Gonna run the plumbing for another livewell in the little boat so have to make a trip to Academy Sports for some bilge hose today.

I did manage to find my electrical gremlin yesterday. It ended up being a bad circuit breaker that feeds everything in the electronics box. I also took the time to spray all my other exposed connections with some corrosion X. And like Phil, I'm still seeing a slight drop, but 0.1 v is realistic. I was closer to 1.1 v prior.

That is some good troubleshooting How did you verify the breaker was bad. (Compare voltage on both sides of the breaker. What was coming in compared to what was coming out???)

Yep, had full battery voltage prior to the breaker and a significant loss after the breaker.

I found a similar problem with my recirculation pump today but unlike you, I can't find out why the voltage drop. I've got 12.8 going into the breaker and 12.8 coming out and into the toggle switch when I have the wires disconnected but only 8 volts when I connect the wires to the breaker. I'm guessing the breaker is bad but the same thing happens to the breaker and toggle next to that one. I'll probably run a new hot wire and leave out the breaker tomorrow.
