im tring to figure out whats up with my glowplugs white smoke comes out when i start it so im getting fuel but now glowplug i tested the plug connectors the tested out at around 6 omh is that good or bad. and to truely test the connectors do i need to push the glow plug button ????any help is greatly apprecitated im new to all this diesel stuff and i dont know what im doing yet....thank for looking..

 

I'm not really familiar with the older ones but 6 ohms isnt to bad for the newer ones. Have you checked the relay?

 

no i havent yet.whats the best way to test a relay???

 

If its like the ones on the newer 7.3's you will always have 12v on the battery side and when you turn the key on you will have 12v on the gp side. Now I have never worked on the older ones so i'm not sure what they have but thats a start. I spend my days on 95 and up 7.3's, 6.0's and 6.4's. Too young for idi's and 6.9's!

 

to test the glowplug relay i have a glow plug botton in side cab do i need to push thatwhile testing the glow plug relay with a meter????? or can i just turn the key and test it with out push botton? HELP HELP. thank peter

 

to test the glow plug side of the relay you will have to do what ever it takes to activate the glow plug relay. If on the older models thats a button you will have to push that.

 

Run a 12v hot lead from bat + to the trigger side of the relay. That should turn it on...

They have a 14 second maximum on time if the controller is working correctly.
