I'll cut straight to the chase on this one as I've been through a lot of diagnostics to solve my problem.
Basically, my glow plugs are not heating and the old shed is having starting issues. Having dived into the Ebox (under the hood) and found the glowplug relay there is a damn big red cable that is attached to the relay (12v 100A I think) however, when at rest this cable has 2.5 volts when at key pos 2 it drops to 0 volts. I suspect that there is something a little wrong here, but before I shell out on a new relay does anyone know what power should on this fat red cable and when? The relay does click when activated but what I do not understand is why is there only one red cable going to the relay, I thought it it were switching there should be at least two!
Any experts out there that can point me in the right direction?
