I cleaned the contacts on the coil and used some tune-up grease and it started and ran fine. I checked voltages and they seemed to show low voltage at the coil which is why I cleaned the contacts. 9V is ok, 6V is minimum, 12V is maximum. It was at 6V. So afterwards it was at 9V and we're good. When the Alternator kicks in, you see 11.5V so no problem now.
The truck is very old, old enough for contacts to rust. Still going though, I constantly get people coming up and asking to buy it. The thing is older than me and worth way more than what I could sell it for. Newer trucks are literally junk.
