Problems continue. I haven't posted since last week just been too busy. But this happened a week ago. I had a mechanic install a new ignition switch and it started up and ran fine. I stopped on the way home and it started back up. I parked down the street a bit from my house to move cars to get my trailer and it did it again meaning the starter spun out of control when I went to move it again. I put the original ford solenoid back on the bronco and it started and ran. I was able to move it to the front yard of my house in my yard and I cut the engine. Then, when I went to restart the engine, it did nothing. It make a bit of a click or I should say the dash lights and what not came on but it would not turn over like a dead battery would. I checked the battery was at 13 volts. Now it is sitting with the neg cable disconnected.
So it has had a new starter, ignition switch, new solenoid (actually original working solenoid is back on it after it did it again when the 2nd new one was on it after the mechanic suggested putting the original ford one back on)
I am stumped and don't know where to start troubleshooting. I suspected a ground but when switching the solenoid back to original, it never spun out of control now it just won't start.
