No Signal To The Glow Plug Relay
I searched for a while but can't find the answer.
I thought my glow plug relay went out so I replaced it. I used a test light and found that the one side that is always hot is hot. But the side that should get hot when I turn the key to the on position never gets hot. Like a dummy I did not bother to check anything else and bought a new relay. I figured it was old enough. But after putting in the new relay it still does the same thing.
So I got out my volt meter to check the small terminals on the relay and they never get any power to them. All of my fuses under the hood seem to be fine. Not sure exactly what fuse is in control of the relay.
In the morning I have to pop the hood and use a screwdriver or whatever to jump the relay. For the rest of the day it starts fine. Would be nice not to have to crawl around the truck in the morning.
