I'm new to this forum as I've just bought a 1999 Astra 1.7TD. Picked it up cheap due to no MOT/Tax and a Power Steering problem.
I've spent the last week looking through diferent Forums and a billion posts on power steering issues so first off, I apologise for the necessity to bring up yet again.
There doesn't seem to be any leaks from the PAS pump or fluid housing nor from the steering rack.
The ABS/PAS fuse (No. 23 under dash) is fine and ABS dash light illuminates and turns off as it should after a few seconds.
Is there another fuse in the engine bay that the PAS uses that I should check?
The alternator is 100% and the car has a brand new heavy duty battery.
Ok, my need is this I've ascertained that my car has the Delphi pump and understand there is a wiring loom for supply and earth which I think is the next step for elimination but I kind of need a point in the right direction. Is it possible to use a multimeter to check the wiring for a supply & if so, what voltage should I be reading? This should eliminate pretty much everything leaving the fault cause to be the pump or rack if I am correct?
p.s. If anyone has a picture or a link to a picture of the wiring and where the suplly goes to and where the earth goes it would be greatly appreciated
Thanks in advance.
