Hi people!
My old GW has become impossible to start without running the diesel heater.
The engine was swapped from an M110 to a OM617 in the 90s. The glow relay is manually operated using a switch.
While glowing, am I correct you should feel the plugs becoming hot to the touch? Cause they remain ice cold.
From what I know, if one fail, they all stop glowing (being connected in series). I then measured using a voltmeter between ground and each of the glow plugs, and got solid voltage on all of them. Is it possible to read good voltage on a busted glow plug?
Thanks for any insight
