I have a 1982 k20 chev 4x4. I recently put in a bypass button for the glow plugs. When I first turn the key on and hit the button I here it click and the glow plug light comes, I hold it for about 6 or 7 seconds, if the truck doesn't start the first time, when I turn the key again there is no clicking or lite. The relay on the drivers side inner fender has a 2 prong plug on the side of it. I hooked one of the wires to the s terminal on the bypass.If I jump the relay with a 12 gauge wire to both the large posts on the relay the like comes on but no clicking and the truck will start after a couple of tries. Is there something I did wrong? Thanks for any help.
