'77 Powerwagon, automatic trans. - has run great! Up until recently.
Turn the key and....nothing. No cranking, no grinding, no clicking, nothing.
I've tested the battery, the starter, the fuses. Lights come on, radio comes on.
Here is what I have checked since my original post:
Battery - full charge
Starter - (tested at an Autozone as well as put a screwdriver on it while installed on the truck), tries turning over.
Relay - installed brand new one
I have been offered the following suggestions (both on this board and offline)
Distributor and timing.
Ballast Resistor
Ignition box
Key Switch
Clean the connections
Red wire from ignition switch.
I am thinking I want to check/replace the ballast resistor first and then start checking wiring.
I'm not a big truck mechanic but I do mechanic work on other machinery at my job and it seems like the fault is happening sometime after the key but before the starter. Is this a fair assumption?
What are your thoughts or suggestions? Is there something in the recommendations I should be focusing on more?
