How does the rev counter work on my diesel escort.As i got an annoying screech on initial start up like a loose/worn belt.Belts have been changed so it not them but then noticed the noise goes when rev counter starts to work.Rev counter doesnt seem to work properly until noise has gone.

Please help doing my head in.

 

the rev counter gets the signal from the alternator, that also explains the connections.

 

That wot i was thinking so sounds like alternator on way out as once the noise goes its fine until i turn off again

 

Your belts are still slipping mate. Once the noise has gone, the belts have gripped and are spinning the alternator which in turn drives the rev counter.

 

The belts are new and tight though have tried wd40.Could it be the alternator itself.

 

Might be worn pulleys....

 

WD40 on the belts?!

 

Makes them grip better so no slippage meaning no sqealing if belts are worn Quick fix if to tight to buy new belts
lol

 

Are you sure? Doesn't sound right to me. (But Ive been wrong before!)

I would have thought it would stop the belts squealing cos they dont grip atall?

I personally would clean all the pulleys with some sort of solvent. Brake cleaner or something else that evaporates completely.

Anyone else subscribe to the WD40 theory?

 

I'd be interested to know the outcome on this as mine does exactly the same

 

WD-40 is widely used in RC-racing as traction additive for rubber tires.

 

you learn something new everyday!

 

well today i have tightened the belt even more and so far the squealing has gone so will try it for a few days and see how it goes

 

it does work mate

 

Let us know how you get on m8

 

wd40 is a lubricant though?!

not saying you're wrong you clearly aint but its new to me!

 

thats just what i thought mate, but it does work
