View attachment 665225I had a friend stop by and ask if I could check his glow plugs. No problem. I pulled them all out and bench tested them like I always do.
View attachment 665227View attachment 665228I used the old battery charger test method and all 8 worked but 1 had a strage way of getting hot. It got hot back at the threads and at the tip. I could smell plastic burning when it got hot. I got it real hot just to show the burn pattern. No flash lights out.

He started it with magic spray to get here and I replaced 1 glow plug and he was here a few hours messing around and when he went to leave the wait light came on and it started right up. That was easy. next week we would like to put this fuel pump on. It would be the pump and filter all in one easy to maintain assembly.
View attachment 665226Not sure what it was made for but it was in a box of parts a friend gave me. That glow plug getting hot at both ends is a prime example of why I always remove the glow plugs to test them. This is not the first time I have encountered this. It don't take me but about 15-20 minutes to R & R the glow plugs and replace the ones that are bad only.
