Hi Bill,

I got the replacement unit and will post back the faulty one in the morning, have the new one attached and was connecting things up to see it all light up nicely.. which it did, for the most part - however, the one glowplug driver doesnt seem to work (properly?) the red LED associated with it continues to blink slowly as if there was nothing plugged into it, with the other one, the red LED goes solid.. the amber led's on the drivers both turn on.. where do i start looking for a fault if it is not a faulty unit?

thanks in advance!

Rob
