Re:No Glow
I done the glow plugs last fall and it has set a lot since I've been towing with the Ram. The light on the dash don't come on,and no juice to the glow's.

Re:No Glow
I doubt all the plugs went bad unless the relay stuck in the "on"position. Which happened to me once.<br><br>Check the wires at the GPs to see if the wire is hot. A Simple automotive light tester will do.<br><br>Does the Wait to start light cycle? and the lift pump prime when you turn the key on.<br><br>If not. possibly the relay is stuck in the Off position.<br><br>The relay is located in different positions in different trucks. I dont know the specifics.<br><br>If the air temperature gets to 40-50 degress it should start without the glows.<br><br>dont ever use ether on a diesel...EVER!

C'mon over and I'll show ya the can that mounts on the firewall of the 'ol dump truck. Button on the dash. Also handy to get any type of earth moving equipment going in the cold cold north. The key is how much to use. That is where the damage starts. The GM, F*rd and CTD are not designed to run on either.

Probably wouldn't have fount it without your help. MEANY THANKS.<br>God Bless America,and support our troops.

If you ever notice your glow plugs cycling when they shouldnt (i.e. once the engine is warmed up) it can be a sign that this controller has gone bad.<br>It happend to me. I was on a trip, had been driving for a while, and then noticed my glow plugs stated to cycle.<br><br>I unclipped the wiring harness from the controller, and continued to drive without issue. <br>Replaced the controller and problem solved.<br><br>Rich

Re:No Glow
Thanks,I will keep an eye on it. It is a little old and has 455,000 on it. Sure hope this one that cost 10 times as much will do that a lot cheaper.<br><br>As for : old reliable,what am I supposed to drive while waiting for parts,getting into a shop and all the other fun of the great white? First failure in about 5 yrs. Not driven much.
