Glow plug/card/relay problem UPDATE -ITS THE PLUGS!!
I tried searching for this, but came up with nothing..
I can't quite figure out where the issue is, as everything seems to be working properly, but something isn't! I recently replaced my GP's. All get volts, and are in working order. Relay clicks on when I turn the key. Wait light comes on, then goes off. But, the truck is getting progressively harder to start.
The issue seems to be that the plugs aren't glowing for long enough. When monitoring the voltage to the GP's as I turn the key on, they get voltage for about 4 seconds, then the relay clicks off for about 2-3 seconds. It then clicks on again for about 2 seconds, then clicks off. It continues that cycle for about 10 seconds, but it seems that the plugs aren't getting voltage long enough to actually get hot. Once the motor is started and hot, it fires on the first revolution every time.
Where and what should I be looking for? Is my card going bad - not commanding the relay on for long enough? Is my relay going bad - shutting off early due to bad internal parts??
What would you replace first?
