Hi all,
I have a couple of tech questions that I need help with please, firstly, I have bought an after market loom for my radiator fans and need to know which wire in the radiator fan switch goes to earth and which goes signal?

Secondly, I have fitted a fuel lad pressure reg and need to know what to set the fuel pressure at with the vac off?

Any help will be greatly appreciated

Thanks
Andrew.

 

Help Please!

 

If its a sierra switch, then it doesnt matter which way round.

As for the reg, why are you replacing it ?

 

Hi
Thanks for the help.

Ref the reg - i have changed the inlet manifold for a swedish one for no other reason but the fact i like them. (pics to follow soon) so i decided to change the reg and fuel rail too.

Thanks Again

Andrew

 

Be careful, some of those fuel regs are dodgy, it wasn't an Ebay special was it?

Pressure is 3.5 BAR, as standard, BUT this can vary depending on software etc.

And it wants to be a 1:1 rising reg too
