Help me identify a rely

[cjs]

I have a buzzing rely on my 92 Griff. I've had the foot-well cover off and driven around but cannot identify which rely it is.

The buzzing appears to happen when the engine is over-running, as I slow under engine braking. Can also happen on full chat acceleration however this is less obvious.

Any ideas which rely could be on its way out?

I've had this several times in the past and every time its been down to the otter switch on the swirl pot failing. A quick test to rule it out is to disconnect the wires from otter switch and shot them (this will keep your fans on constant) then drive around the block to see if the relay stops buzzing.

Hmmm...thanks I'll give that a go, will not be until the weekend unfortunately.

PS why am I spelling relay incorrectly!

I had a buzzing relay symptom once when my passenger door light switch developed a intermitant fault, also worth checking.
