Having spent many a happy hour trying to get my VDO O/P gauge to function (!)....... I'd like to seek advice. So if you had a 12v supply, an o/p gauge and a sending thing screwed into the cylinder block, could you describe where to put the wires? Does a live wire go into the gauge at (+) come out at (-) then go to one terminal on the the sender, then go to ground from the other? Or does the 12v + go into the sender, then on to the gauge, then to gound? And why does the gauge have three terminals plus a self contained light unit?
Sometimes outboards seem to have certain attractions!
Thanks - yet again.
