Hi having issues with boost on my rs turbo. The Amal valve clicks every time I turn the ignition on so seems to be working however sometimes it only boosts to 0.7bar then 1.2bar. With the Amal valve unplugged it goes to 0.7bar. I've fitted new connectors on the valve but still no joy. Where do the wires go to? I've tried checking the voltage and I'm getting 1.0volt when I check both wires and 12 volts coming out of the black wire when I put negative probe on an earth. The green/brown wire has no voltage. Was also thinking duff air temp sensor or tired wiring to it?
Thanks Marc
