HELP!!!

[BrianW]

I have a 83 bronc full-size auto trans. I replaced the starter,solenoid and battery. All the electronics work but when I turn the key I hear a grinding from the solenoid and it won't turn over. Any idea as to what it is?

Starter Motor Does Not Crank Engine

Loose or corroded battery cable connections.

Undercharged battery. Does horn & headlights work?

Malfunctioning starter relay.

Faulty starter motor ground circuit.

Malfunctioning starter motor.

Malfunctioning ignition/push-button switch.

CHECK CONNECTIONS AT BATTERIES

Inspect the battery terminals for loose or corroded connections

Make sure transmission is in neutral or Park and parking brake is applied.

Seabronc's relay PIC

Press remote starter switch button.

or use small jumper between battery + and ignition wire on small relay terminal post (pull the R/LB wire off and try).

With key in START position, check for battery voltage at terminal (R/LB).

Check for continuity between relay mounting bracket and clean chassis ground.

my two cents........ If it's a true grinding noise, it's not coming from the solenoid. I would check your starter ring gear.

Yea, If you are getting grinding it sounds like the gears are not making good contact with the flywheel. Difference between 302 and 351 starter or auto VS manual?
