ukester, Yes I do have three thick green wires in my overhead accessory panel. One green wire is a stand alone circuit from the water pump circuit breaker (feed side) in the overhead to my "Fresh Water" pump. The other two green wires are in my "Blower" circuit, these two green wires both connect to the blower circuit breaker (feed side) in the overhead, one green feed wire goes directly to the two blower motors aft while the other green feed wire goes to the blower circuit breaker (feed side) at my fly bridge, this way the blowers can be turned on or off from either station. If you need more help sorting this out just reach out.

The 2 black wires that feed the 2 bilge pumps where does the power come from? Took out many of the electrics out of the engine room and there is no power coming off either wire.

Thanks

Mark,
I recommend a local electrician help you trace it all out as I may confuse things for you remotely without actually seeing what you have. I am reluctant to advise you without seeing your wiring, circuits and components for myself. I apologize, but I don't want to set you up for a failure, just too much can go wrong if it isn't done right. Where's your boat? I travel a lot.

I could be very wrong here, but wouldn't the load side be cold until the breaker is switched on, and the feed side be the "hot'" side? Kind of like "line" and "load" side for 120 volt?

I guess another question this time ignition hot lead going to the flybridge ignition-the upper ignition wires are only hot when the lower helm switches are on-second question is if both battery switches are off nothing gets power but if they are still off having the battery charger on will give power 12v to the boat? The reason I am asking this is I really want to leave the bildge pumps on but not much else, my thinking is if a large power surge were to happen the breaker 120v would turn off.


thanks

Today I installed the two fuse blocks I wrote about earlier in this topic string. Fuse Block No.1 and Fuse lock No.2. The two circuit breakers for these two fuse blocks are located in my overhead 12 Volt DC Accessory Panel and can be individually switched on or off from there. I will be wiring all of my additional accessories to these two fuse blocks. I mounted them inside of the main helm station pedestal box in the salon and can easily access them through the access door located there.
