    '88 Bronco II with 2.9L V6 and auto.

    Won't crank.

    Had battery load tested. Good.

    Starter was bad. Replaced.

    Unk solenoid, but it is easily bypassed.

    Battery cables are good, including ground.

    Simply cannot get it to turn over. Can hear the dual clicks of the solenoid and the starter circuit kicking in, even when shorting the battery terminals on the solenoid.

    It's acting like the engine is locked, but we can turn it over by hand (3/4 socket and breaker bar, without excessive effort).

    At this point I'm not sure what to check. Going over the schematics.

    Check to make sure full voltage is going from ignition switch to voltage regulator to the starter solenoid. If you are not getting full juice from the voltage regulator it will cause the clicks as it doesn't have enough to turn it. This can happen even with a good battery. Slight chance it could be a bad igition switch. Check negative ground cable as well.

    On a side note: I had one of those Bronco II's. Does the power steering pump leak like a sieve? Never could keep a good one on mine.

    Assuming for the moment the battery really is good, and the terminal connections good, I would take a pair of good jumper cables, hook one end each to the negative and positive battery terminal, clamp the negative load end to the starter housing or close to it, and slap the positive battery cable terminal on the bendix. Make sure the car is in neutral. This should give you a yes or no on the basic condition of the starter/bendix. If it turns over with gusto start back tracking with your positive side cable. It could be a bad cable/terminal, bad contacts in the solenoid (just because it pulls in doesn't mean current is flowing) or an internal contact situation in the starter. It's easy to have enough power to pull in the solenoid bendix but not enough to turn over the motor.

    It was the fender mounted solenoid.

    I've never seen a solenoid on a Ford that could not be bypassed with a heavy bar or wrench across the main solenoid terminals. But I have now.

    And as noted, the starter was fried. It actually started smoking on the load test machine at Schucks. It must have drawn enough current to fry the solenoid.

    At least Sean in Oregon now has wheels while he's here for Christmas break.

    Thanks for the suggestions.

    Well, spoke too soon...

    Smoke coming out of the positive battery terminal when starting. Solenoid chattering like a squirrel on meth.

    Having Sean pull the terminal and clean it and the post, then try again.

    Well, cleaning the terminals seems to have fixed that problem.

    Have ths starter checked and the solenoid checked, and or recheck for a ground side of the cirucit.

    Brian,

    If your problem persists, you need to check your distributor. There is an electronic module that mounts to the distributor and that can either go completely out or it will be intermittent. It's kind of hard to get to it as the distributor is mounted to the back of the engine block. Just climb up in the compartment and reach back there to unbolt it. Here's a picture.

    The first problem I seen was 88 Bronco II. These where about as reliable as the Aries K car, from what I recall. I may be wrong. Jon

    I always dreaded working on them. Pure junk and they drive like goats nightmare.
