Short glow plug power up
HELP, I have a 300D 1983 Mercedes, all glo plugs good, new glow plug relay installed, all wires tested, ignition sw disables glo plug when turned all the way on, problem is that the glow plugs and lamp only stay on a few seconds, not long enough to get them hot. I searched the wire harness and found one wire from the glo plug relay going to the fuel guage of the dash, it does not say if it is supplying a voltage or not to it but the guage shows empty, I assume this is a safty device. the wire is a W/bl g connected to #15 on the glow plug relay. To temp. fix this do I apply 12 volts to it, ground it or should I just sever the connection till I can afford a new fuel sender unit?
