I have designed a cheap and reliable glow plug timer for my 6.2. Should cost no more than 40 bucks..
Some background first.
My new to me 82 C10 has a manual glow plug button. It works fine. Turn the key on, hold the button down for 6 seconds or so, release, then start the truck. Works every time.
I can't stand it. I hate having to hold a button down every time I have to start the truck. Granted, it's a great anti-theft device, but when someone else needs to use the truck, I always have to teach them. If they forget, I end up with a phone call saying the truck wont start...
Going back to a stock style system isn't cost effective, and the original design isn't great anyway.
So... here's my plan.
I've ordered a Mini Timer Time Delay Relay off of amazon.
Looking at the manual, it is capable of supplying power for x number of seconds, using the configuration that they designate as Function 2.
Now. My existing glow plug button is only a ground switch. So, using a relay, I plan on using the positive output on the Timer relay, to switch a standard relay and close the ground loop. By utilizing the Ignition source at the fuse block for my switched power for the Timer relay, I will be able to cycle the glow plugs as needed in colder temps.
I plan on starting with a 8 second delay, as it will most likely work the best.
I've got it hooked up and it works great! I couldn't be happier on how it turned out. Turn the key to the on position, wait for the glow plug light to turn off, and start the truck.
I noticed that I made a mistake in my wiring diagram... on the relay, Pin 30 is grounded to the chassis, pin 87 goes to the stock glow plug relay on the drivers side fender.
I'll get some pictures and a video later on today.
