Relay - heat in wire. Replacement part?

it's a coil and a switch. same as 95% of all relays. just need to match voltage and current ratings. and if switch is normally open or closed. yours is normally open which is the 95% side.

The ignition key activates the solenoid, right upper in photo. The little blue wire goes from the solenoid to the relay.

Yes. It needs to be worked out. But its beyond me. Its going to be expensive to change the whole concept of what Beneteau has built. I need a good marine electrician to review it. Won't be easy to find one with Beneteau experience.

Beneteau experience? Electricity isn't boat sensitive. Try cleaning up the spade connector.

It's not a Bosch-type automotive relay, doesn't have the ISO terminal designations.
Looks like an abnormal ('cause it's French) SPST NO 12V 50amp relay, activated by whatever operates the solenoid next to it.
Any single-pole-single-throw-normally-open 12 volt 50 amp 1/4" (6mm) spade terminal relay should replace it.

The relay I linked to is configured exactly the same as yours in the photo.

The blue wire from the solenoid to the relay is the ground. The red wires are the circuit that is being switched. Find both ends of this red wire and you find the function of the relay. My guess it's something like a blower or electric fuel pump switched with the ignition.

Another easy way to find out what it does is disconnect one of the red wires and see what doesn't work.

These are very basic relays. Yanmar probably sells them for 30-70 a piece. Can get 5 for around 15 on EBay. A relay is a relay, just have to make sure the current carrying spec is sufficient.

Brilliant advice i get scared of blowing the boat up doing that. So if I don't post anymore you'll know what happened

generally you only blow things up when plugging things in. not unplugging.

Did this job at 1AM only slightly drunk, so Solar panels wouldn't affect it.

Relay Hot.

Disconnected the hottest right Red lead. TERMINAL remained hot.
Disconnected other left Red lea. Right terminal remained hot!
Disconnected Brown lead. Terminal Cooled down.

Whilst 2 Red leads disconnected I reconnected the Brown lead and could hear a click inside the Relay, and relay Red terminals got hot again.

Supposition: The Relay is fried.

Is that correct?

Without the leads on, started engine and no engine room blower.
Replaced the leads and started engine and still no engine room blower.

Supposition: Relay controls engine room blower.

Do you guys agree?

Mark if it's for the blower, jumping out the two red wires will start the blower, assuming blower is in working condition.

[Sailmonkey]

You may have already said this......

Was/is the relay activated by the ignition?

And, you can check the function of the attached device by doing as the previous post says.....touch the red leads together.

Touched the red wires. Its not the blower. I made a mistake there.

Nothing happens that i can see when the red wires touch. That diesnt mean nithing happens.

But the important point is the relay must be shorted? Isnt it? So if i replace the relay whatever is meant to happen will happen?

[foufou]

In addition to all the above good comments it might help to put an ammeter on the red wire to see that the current is within the rating of the relay. At least determine if the current is normal for intended purpose. f

Does the relay energize with the ignition switch?

But, yes it should not be hot.

I have just sold a 323 with a similar Sunsail setup. The Hella (box shaped) relay is activated by the ignition and in turn it activates the two bigger grey relays/solenoids that a) combine the batteries and b) feed the relay at the windlass.
If the Hella relay does not last long then it may be that the coil of the grey relay that combines the batteries is consuming too much current.
