i can check the glow plug system on my 85. the controller is different. it's similar to the 6.5 controller. I believe there is a controller card that controls the relay. It's job is to turn the GPs on for a set amount of time and then cycle them a few times. I have no idea how it works but maybe your is missing or burnt out?

I parked my identical SF Sub rite next to it, and swapped relays, yada, yada... I'll show more tomorrow...

hey corvair ill make a video of my chilton manual in a few minutes my camera battery is charging. it shows how the 1982-1984 glow plug systems work on these trucks. has a diagram and a description.

Sounds good. I bought an extra fake genuine batt for $5 on ebay

if i remember right one terminal needs 12V+ and the other needs ground to operate properly. thats what the temperture sender in the cylinder head gives it when it wants the glows to glow.

[CORVAIRWILD]

I ran 12volts directly to the pink terminal...

YOUR PROBLEM IS THE TWO LETTERS "GM" ha ha

yeah make sure everythin is tightin down and if if it is bad u should e able to jump the relay but just buy another and say ITS ZEEE JUNKK lol

The blue wire isn't grounding.

rig up a magic button (manual glue plug button) . i had a diesel silverado once that the relay did not work and thats what i did and then the relay worked

the solanoid is probably bad. theres now real way to check the relay youve shown youve got juice all around it i would guesstmate the relay is bad. ive have a good question for you; i have found a blazer like yours in a salvadge yard 6.2 ltr diesel. its 12 volt but has 2 alternators both of them are reasonenably heavy duty. whats up w/ that? im almost thinking an aux. power source of some kind.

is that rust around the windsheild? =0

could be bad relays bad grounding or low volts miss up batter's wire it could be the key switch link rod to the mane switch box but more then like'ly it the f**k'in mane relay

Just to help you out. When i replaced my dana 44 front to a dana 60 it bolted right in with the 60 spring plates. Only problem was the rubber brake lines are smaller fitting at caliper end on 60 than 44 order up new lines for 1 ton bolt right in

Have you checked the ground wire that goes to the relay?

[contrapezist]

According to what ive researched grounding the blue wire should activate the relay. Normally its grounded via the controller when their needed. The red wire is always hot when the ign is turned on. With a controller that diode is important it keeps the spike out of it. Go to rat shack and get 276-1102 install across the red and blue wires with the white line pointing to the red terminal. Then find out why the controller isnt working possibly bad ground to controller. Need wiring diagram.
