Default Re: Fiesta - where is the glow plug relay?

Thanks 11ford11 - I had initially dismissed that relay because the manual called its function 'ignition' - which in retrospect, probably is for the glow plugs, but I thought it had another function. It's rated at 70 Amps which sounds about right for 4 x 10 Amp glow plugs.

Unfortunately the relay appears to be working in that the 70 Amp contacts make when 12 V is applied to the coil.

I also checked that there was voltage going to the coil when the ignition was turned on. The voltage appeared to stay there as long as the ignition was on - that is, it did not time out after 5 or even 10 seconds. (The relay was not plugged in for this test.)

So the question now is why don't the new glow plugs pull 10 Amps each? I still don't reckon that they are seeing any volts.

Not sure what my next step should be.....

Any tips welcome!
