Help Cooling problem

[ALANV8]

HELP the right hand cooling fan has stopped working on my 95 griff500, i was able to drive the car home ok but it was struggling to keep the temperture down in slow moving traffic.
I have started to investigate the problem but so far with no success.
Fan motor is ok as it works if you plug it into the other connector.
Cooling fan fuse is ok
Relay is clicking in and out when otter switch is shorted.
Horn fuse is ok ( I've heard some cars had there second fan wired to the horn circuit as this reduced the load on the fans circuit.
Earth is ok on connector of non working fan.

Does anyone know if there are any in line fuses anywhere.
Thanks for any help

HAve youmade sure the connector just down from the fan motor is ok as i had a problem with mine, it had corroded quite badly and wasnt making a good cotct and while the other fan was running if u wiggled allsorts of sparking happened(load).
Bypass the Otter switch with a bit of wire so the fans are on and give it ago.

All the best

Yes i've tried that, the connector was quite corroded so i cut it off. tested with the otter switch shorted and no voltage, 12v on the other connector which makes me wonder whether the two fans are supplied seperately, though there appears to be only one relay

Thanks

Have you checked it is free to rotate. On my current car (not a TVR ) my electric fan kept popping fuses and I dscovered a twig/branch stopping it rotating.

Yes i'ved tried this and the fan motor is ok as i've plugged it into the other connector. I just can't find where the other fan is supplied from

It sounds like you have the two fuse/relay set up. Have you tried just pulling all the fuses in turn and checking each one.

Cheers,

Simon.

I seem to remember someone with the single fuse set up having the same problem and was the fuse box, very expensive. But of course there is a much cheaper way and will give better cooling also.

What is this better way?

there is (on mine) a connector to extend the wiring from the original otter switch (in the block) to the new TVR one in the swirl pot. if you have no volts at the otter, check here.

mine is in the mass of crap (and now replaced) wiring at the front of the block by the dizzy.

the connector is taped up for (crap) insulation and in my case was just the usual Lucas spade type.

this happened to me. as did the front fan connector!

useful to know of the original otter in an emegency...mine is in the casting for the water exit from the block, by the thermostat.

check connector, and volts

good luck

Take the second fan supply from the starter motor, through a relay. It will give much greater power to both fans, that aint no bad thing. Of course you also get half speed fans before the full speed fans come on, fully adjustable cut in point. It just plugs in.
