I will try and find more info in the tm but sometimes IMO its a little difficult. Thought it was a variable resistor due to the tm says check for 600 ohms cold if its open check wiring and the glow plug switch. Unless its 600 ohms during cold and when hot it closes the switch, the tms dont tell...

Also when the engine is warm it will cycle the glow plugs it has done that since i got it thought it was suppose to do that but I found out its not.

If I was the only driver I would remove controller install push button with a analog volt meter that is hooked to the output of the glow plug relay. This way I can monitor the voltage going to the glow plugs.

So in this whole process of troubleshooting it looks like I dont have after glow anymore also. So I need to see if my glow plug temp switch is working actually its not really a switch is it more of a variable resistor. It use to work so not sure if the only thing wrong is the resistor.

Yes I am thinking of removing the resistor pack that will need to upsize the wire to the 12 volt terminal.. I am thinking at least a 6 gauge but a 4 would be better not sure how I am going to fuse it though. Larger the wire the less voltage drop across it in turn hotter plug temps. So does the...

Should have mentioned all voltages were taken with glow plugs cycling, So I had 24.9vdc then went to 23.6vdc with the glow plugs on so only a 1.3vdc drop from the batteries under the glow plug load. Next time I will check it at the 24vdc bus bar with glow plugs on and also when the starter is...

I am doing this testing every day to make sure the truck is cold.

I replaced all eight glow plugs from the wellmans to ac 60g four of the wellmans were open. Definately helped it starting but when it didnt start very good the other day. Checked all 60g all ok during glow plug cycle had 9.0 volts on the output of the relay. Next day I checked the input to...
