glow plug resistor on 73 220d
I am having issues starting my 220d cold. it seems as though there is excess resitance in the glow plug circuit.
Yes I did take electrical readings and I found that the voltage reaching the first plug in the series (cyl. 4) is reading 9. something V, battery voltage being about 12.2v. I proceeded to measure the voltage drop between plug #1 (cyl 4) and battery positive and I got 1.something volts.
Sounds to me like my glow plug resistor aka saltshaker needs to be changed
it also never seems to glow as bright as it should.
is there any other thing that might cause this? I looked at the wiring diagram and it seems pretty straightforward to me.
All comments and insights are very much appreciated, Thank you!
