Hi,
I have a 1997 Griff and having a problem.
The car was overheating due to the fans not cutting in. Checked the fuses and ok.
Started the car again to re-check the fans and noticed all the lights and indicators had come on !
Bad earth ? Where do I start the search ?
Cheers
Yes you've got it in one, check the earths. The main battery to body earth could be the problemI have a 1997 Griff and having a problem.

The nearest earth point to the fans and also the most vulnerable from a corrosion point of view is the one in the very front of the lower longitudinal offside chassis rail. Quite a few earth cables are fixed here via a bolt into a threaded hole in the rail.
The earth fixing bolt is visible through the wire grille which is in front of the radiator....accessing it might not be so easy but a very long extension might just get there.
It might be worth running a temporary earth cable to the fans first to see if this is the cause.

The most common fault with cooling fans on the Chimaera is the connectors in the wiring just before the wires get to the fans. The connectors get full of water and corrosion. A good clean will solve the problem.
You can test whether this is the problem by taking the two wires off the otter switch and joining them together with a paper clip or whatever. Or if you pull them only half off, you can bridge by holding a small screwdriver blade across the exposed terminals.
Fans should then come on with the ignition regardless of the temperature of the water.
If you need to know where the otter switch is, just ask.
On a Chimaera it is under the swirl pot (early cars) or on the back top left of the radiator (about 1997 onwards).
My Griff knowledge only extends as far as chest wigs and medallions, sorry.
