Check the CUCV tech manuals for troubleshooting procedures however in our experience this is what we check/replace when having trouble with the glow plugs:
1. Glow plugs themselves (a continuity check will tell you if they are burned out, no continuity = burned out)
2. Controller Card Shown here. A button cannot re-create the functions handled by this card.
3. Solenoid/Relay on the firewall.
Please note, sorry, but we are unable to provide troubleshooting support over the phone/email.

Plug in and turn the key works great
The glow plug card worked exactly as it should. This truck even has the large resistor bypassed and is running the gpr on 12v. All email was responded to promptly. Thanks.

This is the starting point for repairing a glow plug system. If it does not fix the issue, it helps identify other problems as you can use the LEDs to watch it function. I have purchased two of these recently, and both times it was a breeze to install. I have two cucv's here that both start easily in 20 degree weather. Thank you John for your help!
our dead truck came to life with one key turn after installing this glow plug card. realy, that easy. My sons truck was missing this item completely, this was sent fast and did as quoted. Thanks !! Street-Mafia-BMX
That new card worked perfectly right out of the box!! And the LED lights take the guess work out of function testing! If only the factory units had been this dependable the Army might still be using the CUCV with the 6.2!!
I recently acquired an M1009 from GL that I was in the process of shaking down. While trouble shooting the Glow Plug system I inadvertently damaged the original controller board while trying to remove it, apparently it had been in there for a while as it was basically corroded to the contacts. After removing it I was stuck with a cracked board. I found this product thru a quick search and was pleasantly surprised at price compared to others on Fleabay and others. Once installed the LED's , not present on the factory board aided in the trouble shooting process and basically acted as a separate set of hands, as are sometimes needed. Shipping was fast and I was kept up to date on its progress. Can't ask for much more. Thanks for a great product.
