Re: glow plugs testing

Yes indeed the two brown/white wires from the fuse holder go to a single terminal on the relay. The relay has 4 terminals: from the fuse holder (brown/white) to the resistor (brown) from the battery plus? (red) to ground on engine block ( Hi Yoramy, I think the red wire should go to the ignition sw...

If the two brown and white wires are both connected to the upper terminal of the relay, it could be that a previous owner used two lower current-rated wires to supply the required current for the heaters. That would mean the voltage is on the side with the taped brown and white wires, the fuses have...

Hi Yoramy, The component marked "Hella" looks like a relay, used to protect the ignition switch from the high current used by the glow plugs. There should be one or two thin wires coming from the ignition switch. When you activate the glow plugs at the ignition switch, this applies 12v to a coil in ...
