new starter wont disengage
One day it just clicked, thought it was battery. next day I go out and it started right up. next time it did that happened I cleaned the main cable on the starter. started it and the the starter seems like its not disengaging, and now its not charging, new starter, new selinoid, full charge battey
if the starter is continuing to crank the solenoid is most likely sticking. New doesn't always mean good. Take an ohm meeter or continuity tester and test if the two large posts of the solenoid have continuity with the wires off the solenoid. If you have continuity the solenoid is sticking. It's a common problem but often misdiagnosed. If the starter is contiuing to run the electrical system will not charge because all the power generated by the alt. will be used by the starter cranking. If I am correct about the solenoid being the issue you may still have the charging problem after the original problem is corrected. The additional load from the contiuous cranking from the starter may either blow your main fuse or burn out your voltage regualtor on your alternator. Good luck hope this helps.
Earlier Fords also had what was referred to as a solenoid bolted to the firewall somewhere around the battery. Power when from the battery to this solenoid then on to the starter. This could be bad also, although usually when it is bad the vehicle will not turn over or stay running. The part is about twelve bucks.
It is possible that as you have changed the starter motor, the fault could lie within the ignition switch, where the switch is not springing back from the 'crank' position.
I had that problem with my 88 Ford econoline motor home. Just fixed it was my starter cable
