antennaclimber Both my trucks have a "cycling after glow" when cold starting. So as you stated above, do I have really good electrical systems in both my trucks? Or do I have issues with both of my trucks? The TM's state the "glow plugs will cycle up to 90 seconds" after start-up. I had a...

Your glow plugs are not cycling after startup and are causing a large draw on your electrical system. You changed your other parts twice to no avail. I hate throwing new parts at an attempt to solve a problem but now it may be time to try another glow plug card.

I still think you may have a bad card, temp sensor, or both. The video shows on "your volt meter" that the GPs were/are fully activated when you started the truck "I assume when the engine was already warm". Also the GPs after glow never worked properly in any of your videos. The after glow...

...see if the Water in Fuel light would still flash if these two items were unplugged. I also wanted to see what would happen with the Glow Plug Card in relation to the Water in Fuel light flashing. I started it up, soon after as the Red Light in the Glow Plug Card Flashed Off the the Water...

Stupid question, I’m still learning: the Water in Fuel light Flashes right before the power goes up into the Green on the Voltmeter. That’s not normal right, the flashing? Afterglow, that’s an interesting thing to learn, makes sense. I’ve thought maybe it (Voltmeter) should go up to normal...

The temp sensor for the glow plug card is a thermistor. It changes resistance with temperature change. This resistance value is used to calculate the time that the glow plug relay is closed. The high idle sensor is a switch. It is either open or closed.

...cold". When the water temperature rises after starting or when it has already been running, the sensor loop closes and that tells your glow plug card that the engine is warm and doesn't need the glow plug system any longer. I also could have that all reversed. The sensor "cold" can be a...

...this is what happened: after I replaced the glow plugs and the GP relay, (Napa ST85 but ST94 also works) but, because of a bad glow plug card (not known at this time yet) the glow plugs stayed on all of the time, this apparently draws about 100 amps and had my alt 1 working super hard which...

@dougco1 I switched the glow plug cards out. Still the same thing. I was thinking about it all. It did all of this before and after I replaced the Temperature Sensor. Maybe it’s the Glow Plug Relay? I replaced it last year though. As far as the New Temp Sensor, is there a way to Test it? More...

The Wait Light is functioning normally. You have me thinking. I do have my old card, I’ll try switching it out and see if anything changes. I’ll report back soon. Thank you for the advice, I appreciate it. Sent from my iPhone using Tapatalk

The water in fuel circuit would not draw that much power and should have no effect. You are still getting a huge electrical draw "most likely" from your glow plug system. In your video, that rattle noise and then the back to normal acts as if your glow plugs are still heating in till the system...

I went ahead and fixed alternator 2 (I shorted it by accident) and I replaced the Relays for the Voltmeter & Gen 2. I disconnected the Ground Wire from the CB Radio as well. I discovered the previous owner wired it to a Hot Wire. I did this in case it’s drawing power when the vehicle is parked...

I have a issues with my ignition fuse on my 85 1028. It has started blowing the fuse when waiting for the wait light to turn off. The seatbelt buzzer gets quieter just before it blows. It usually takes 4-6 seconds to blow. This is sometimes long enough to start truck but not always. I have...

Thanks to tim292stro for providing the information that the orange wire at the glow plug card is the wire which senses voltage to the glow plugs. Therefore the orange wire should be the source wire to an LED indicator. Thanks again to tim292stro !

I'm installing a manual momentary push button to fire the glow plugs in case the card gets fried. I also want to add a dash-mounted LED to indicate when power is actually being delivered to the glow plugs. I have read all the posts in the sticky regarding such an LED, however there is no...

...The wiring on Old the plug was in bad shape. Even after driving and warming up the vehicle, the power jump still happened. The Glow Plug Card seems good, it wasn’t loose, etc. After all that, the power jump is still occurring. I checked out the plugs on both alternators as well. Both...

Thanks for responding. I did indeed replace the Engine Temperature Sensor when I replaced the Glow Plug Card & Glow Plug Relay. I’m going to double check the Card, make sure it isn’t loose. When I switched to LEDs, I kept the original type of bulbs in Gen. 1 & Gen. 2. I only knew of that...

...a problem with the glow plug system. The engine temperature sensor may be bad and is keeping your glow plugs activated or the glow plug card went bad again. Does it do it when the engine is warm? After reading your post again, you said you replaced your dash bulbs with LEDs. Did you replace...

...this Flash and suddenly power is normal thing. If it matters, I also replaced the both alternators, the temperature sensor, the glow plug card and relay late last year. I’m not sure what exactly is going on. Is it the truck just needing a short time to get back up to the proper volts once...

I got in my truck last week and turned the key to find no power whatsoever. I had driven it to work that morning and I was busy so I left it and went back to my office. Later on I went back to it, fiddled with the wires on the junction above the glow plug relay and it started so I drove it home...
