Electrical Problems on my 1989 Bayliner 2556

[WildeStarr]

First off... thanks to everyone who helped me with the power steering problem a few months back!

Today the following stopped working:
all 12 volt interior lights in the cabin, head, v-berth, etc.
am/fm radio
water pump for sink
water pump for shower drain


I checked fuses at both the upper and lower helms. They seem to be OK. I was told there might be a 3rd set of fuses somewhere on the boat, but I don't know where they are (if there even is a 3rd set). The 3 batteries are brand new. Boat fires up fine. Trim tabs work, running lights work, engine blower/fan works, bilge pumps work, horn works. Shore power seems to be OK (AC outlets work), the 2 courtesy lights on the aft deck work.


Any help would be much appreciated!

Since all those stoped working at the same time, I'd look for a common hot wire or ground wire and check for corrosion.

I agree with Reddogg. It is obvious that all of these are on the same circuit. I would suspect a bad ground. But trace the wire back to the switch box and check every connection. But since they all went, I would think it is at the power from the battery to the positive buss for these items or the ground buss.

All of those are not on the same circuit. I can guarantee they each have a dedicated (hot) circuit for them. They would not install a water pump, a sump pump, radio, and all interior lighting on the same circuit. It sounds like you blew the main fuse in the line that feed a portion of the panel.

Check the power to and from the breakers first.

You are going to have to pull the face off of the panel and make sure you have 12v & ground to the panel, then power and ground to each on the circuits, and then from each circuit to the application. Luckily, you can do this with a test light or (preferably) a multimeter without fear of shock hazard. If you have 110v via shore power going to the boat, make sure it's unplugged first.

Thanks everyone. I will go down to the boat this weekend and see if I can figure this out!

Hey Wilde Starr... did you get your problems resolved ? I have what looks to be the exact problem as you did... cabin lights, radio, shower drain pump all stopped working - well almost, the radio LCD display seems to light up as if it is getting some power, but not enough to work properly.... anyway I have checked all fuses and other in-line fuses none of which are blown, cant think of anything else to check without ripping out all the panels that the wiring is hidden behind. Any findings you may have should be helpful... thanks.
