The first item of business when I got home was to fix the Glow Plug Control circuit.

The problem I had was that the truck would never glow for more than 5 seconds even when it was in the 20's a few nights.

First thing i did was to check all of the glow plugs. I did this by removing them one by one and connecting them to a hot battery.

I found that only 4 of the plugs were still any good and this still didn't explain my short glow timing. While I had them all out I went ahead and replaced all 8 Glow Plugs with AC Delco 60Gs. I liked the fact that they were self-regulating but they definitely heat up much slower.

After verifying good battery voltage to the controller and that the engine temp switch and starter engaged signals were functioning properly I narrowed down my problem to be the Glow Plug Controller itself.

After reading many posts on here and elsewhere about the never ending problems with this circuit I made the decision to convert this truck to a Manual Glow Control Set-up.

I did the conversion using a Starter Solenoid for a Ford 351w V-8 and a Momentary Push Button inside the cab.

Ever since these modifications the truck starts easily no matter how long it has been sitting or what the outside temperature is. As an added bonus I don't think anyone else could get my truck started and take off in it!
