Howdy Folks -
The big green turd has been quite the SOB to start lately. There is no voltage at the cold advance or fast idle leads that connect to the injection pump.
I have replaced the thermo-swtich at the rear of the passenger's side of the block that threads into the block that governs when the cold advance/fast idle leads get voltage. The thermo switch it good.
I tested voltage at the cold advance/fast idle leads at the injection pump - nothing. I tested voltage at the leads that plug into the thermo switch (I believe these leads come from the controller card, based on diagrams F-3, F-4, and F-7.)
To further explain, F-3 Engine Compartment Ignition Circuits, in the upper left of the diagram you see the cold advance control and temperature switch. I tested voltage at both the cold advance control and the col advance temp. switch (.8 LT GRN-936A and .8 LT GRN-936B. Nada, 0 volts. Further towards the source of power, .8 PNK/BLK-39B(SXL) traces to the glow plug module - this is the entirety of my question to this thread)
Is the GLow Plug Module faulty? Gone to shiznitz?
I have verified all fuses in the fuse box are good. I see no other potential causes why the there is no voltage to my cold advance leads.
Any other ideas? Is this how glow plug modules typically fail? What other symptoms can I expect if the Glow Plug Module is on it's way out?
Any suggestions where to purchase a new Glow Plug Module if this one is faulty?
Cheers and thanks in advance,
S
