Hello all,
I have a 2007 2860 and there is a positive feed that comes of the volt sensor to supply the 3 bilge pump breakers. It is one heavy gauge wire pigtailed to the 3 smaller gauge wires going to the breakers. It appears they all have some kind of resistor on them right before the connector to the breakers. I am looking to replace this as it is pretty corroded on the ends were it attaches to the breakers.
I was going to make a new one but when I discovered the resistor I wanted to find out more info.
Any one have any info on this would be much appreciated.
Ralph

They might be thermal overload devices.

Thank you for the replies and wire diagram gentleman. The wire diagram is were the bilge pumps come off the load side of the breakers. This pigtail comes off the voltage sensitive relay and supplies the power to the bilge breakers. I have included pictures. As you can see the one looks like it got hot at one time.

Very interesting that part that you posted fishnfool. Do you think they would have fuses and the circuit breakers?

It wouldn't surprise me if there is both. I am not sure what the ABYC standard is when a breaker is part of the puzzle. I do know it generally calls for an in-line fuse to be installed.
You may want to peak your head in your bilge, trace your wire from the pump and see if there any signs of an in-line fuse down there near the pump, which isn't a good place for a fuse IMO. If it's just a thermal fuse/cutoff it's serving a slightly different purpose than a traditional fuse.

They're not thermal devices after all. After looking more closely at your photos I can tell that they're diodes. Hopefully they have a value printed on them that would allow you to replace if needed. A VOM with a diode checker on it would help you verify if they're good or not.

Very interesting. Mine does not have these. 2008 2860

I might take the heat shrink off one of the other ones to see if I see a value. All the pumps work fine I was just thinking if it wasn't crazy I would change it out because of the way that one looked. Maybe I will clean up the connections and put on new heat shrink. I would guess I would have to get this direct from Sailfish.
Thank you both for taking your time to help.

You don't have to get fuses or the like from Sailfish. You just need to determine what size they are and source a good replacement.

Outtadblue,
How is yours setup if you don't mind me asking? Do you have straight wires with no diodes? I'm thinking the diodes have something to do with them taking the power off of the voltage sensitive relay. Our boat are only one year apart and can't see them changing much but could be wrong.

I do not have diodes on the wires. Straight wires going to the breakers.

That is strange. They did away with the diodes in one year. Anyway thanks for everybody's help and if I come up with anything I will post it.
