I've spent the past couple of hours searching and reading posts on here.
I drove the waggy home today after work. It was running GREAT. Got home where my neighbor needed me to pull his truck out from the side of his house. Waggy pulled the truck fine and was running PERFECT.
Parked and killed the waggy. Came back an hour later to move it to my drive way. Now it won't start.
Here are my symptons and what I know- please help with troubleshooting.
'83 Waggy with Chevy TBI, MSD 6A, TFI Ignition
- Engine cranks good - no start
- All fuses on the fuse block are good
- Battery is fully charged
- All grounding is tight
- All electrical function- interior lights work, radio works, cig lighter works, headlights work, brake lights work, turn signals work.
- TBI computer is not receiving power - thus no fuel pump
- blue wire (battery side) of starter solenoid has 12V when key is on.
- Red wire (starter side) of starter solenoid has .35 volts when the key is ON. (zero voltage when key is off)
- Same red wire (starter side of starter solenoid) has MELTED wiring from the solenoid on into where it merges into the main engine harness. It does not appear to have melted other wires and moves freely within the harness.
- Large (10 or 12 Gauge) Yellow wire comming from the ammeter to ?? get's HOT when you leave the key on for a few minutes. ( I don't know if this is a problem or would be normal if you leave the key on without the engine running)
So basically my problem (I beleive) is that my computer is not receiving power (from the starter side of the solenoid) and the MSD is not receiving a spark signal from the comptuer.
The starter solenoid itself is only a few months old. I "rewired" the underhood of the waggy about a month ago. Have since driven 400 + miles with no issues.
My questions are:
Should the starter side of the solenoid (red wire) have 12V power when the key is "on"? I'm really sure it should as this is where my TBI get's it's power and has been working for well over a year.
What would cause the red starter solenoid wire to get so hot that it melted the insulation.
To my knowledge, it still has the orginal ingition switch. If that was having a problem, it wouldn't crank over right?
