Electrical/ shore power

[Paulairforce]

Howdy all,

Picked up new to me 95 290 sun dancer. Plugged into shore power and turned on breaker. But none of the lights turn on. Panel shows I have power.

Do I need to flip breakers or anything? Also I turned my batteries to off..was that right?

thanks,

paul

All your 12V items, including your lights, get their power from the batteries even when on shore power. So you need battery switches on and 12V breakers on to use them. You should also have a battery charger that runs off the shore 110V power to keep the batteries charged.

Ah..ok so should I have battery switch put to one or both batteries? And if I have the batteries off (now) should I go back to marina and turn one on?

Thanks,

Paul

You should run your house battery(s) for your 12v lights. If you have left the boat for now with the batteries turned off, you are good. I leave my charger on and batteries off when away.

I leave my battery switches on all the time mostly for convenience. Some people turn them off when not on the boat. It doesn't really matter as long as you have a battery charger doing its thing, since all the important stuff (e.g., bilge pumps, mercathode system) is directly wired to the battery and bypasses the battery switches.

OK, went to boat tonight and turned battery to one and all lights work. Also turned on breaker for Ac convert. Thanks for assistance.

(Tried posting pics buy keeps saying over size limit (read FAQ, but I use phone and iPad...)

just make sure that you NEVER turn the battery from 1 to 2 while the engine is running. As to why, it's early and my brain isn't functioning at 100% yet so I can't remember exactly, but I know it says that in my manual and I have read it several times on the forums here.

As I was told in my recent maintenance class it will blow the diodes in your alternator.

Good to know! Thanks for the tip.

this is interesting... i turn my batteries off and leave them on charge from shore power and the fridge kicks over onto shore power when 12v off... so if you leave your 12v on the fridge is always running on 12? and your always charging 12? or will the fridge always run on shorepower when shorepower is present over 12v?

With a 1-2-Both-Off type battery switch you "should" be fine rotating the selector with the engine running as long as you DONT turn it to Off.
Don't rotate through the off position either anytime the engine is running..

I learned this long ago...and then, got to learn how to replace my alternator!

If your out on the hook all day and deplete your house batt. turn to the other batt. start the engine then, switch to both to recharge the depleted batt. on your drive home.
The switch is a constant contact design as long as you stay away from the Off position while running.
