the engine is locked up. Not good. Very expensive.
Then why did you replace a perfectly good starter? ALWAYS test old parts and know what you're doing BEFORE you start throwing new parts at a problem. Find out WHY it isn't starting. Does the starter engage and turn the engine? IF it does, then the starter is probably fine. If not, check the starter, battery, electrical connections, ignition switch and neutral safety switch. If the starter has ALWAYS engaged and turned the engine, you should not have changed the starter in the first place; instead, you should be finding out what's wrong.
Bad or discharged battery, bad ground, dirty connections at the battery, or a bad starter.
If the starter is engaging and the starter is able to turn the engine normally, there is nothing wrong with the solenoid. Instead, I'd look at fuel, ignition and compression.
There are two SMALL wires on the starter. They are connected wrong.
SAME PROBLEM. Reco Holden 186 engine with a clutch. Engine recently fitted with Yella Terra head and 350 Holley. Compression probably high but starter spins the engine ok. I have a starter moter that drops out, as though the engine has fired. Ive disabled the engine from starting and still the starter drops out after perhaps one revolution of the engine. Ive had the starter out and is working fine. The teeth on the cog show no signs of wear nor are the teeth burred in any way. Anyone would call it a good starter. Took it to a auto elec for a second opionion. Its fine. We agreed it was a good idea to shave off three milimeters from the end of the starter to alow the cog to enter into the ring gear ferther. This done and refitted it still drops out before the engine has a chance to fire. Cover plate removed from clutch and inspected ring gear. A few fine burrs or rather a sharp edge on the ring gear was found. Dident think it would affect the starter but filed off the sharp edge and carefully inspected (and checked with a file) each tooth TWICE! Starter still throws out before the engine fires. Still drops out after about one revolution of the engine.
If you're implying that it engages without you turning the key, the problem is one of the following: * a faulty wire somewhere, * the starter solenoid was connected wrong * or the solenoid return spring has broken.
That sounds to me like the solenoid is stuck. That's the part of the starter that engages the gear to the flywheel in order to turn the engine and thus start it. Try tapping the starter a few times with a hammer to knock it loose (I swear this works), then if it keeps happening to you it's time to buy a new starter yo.
broken tooth on the fly wheel if your starter is turning over and not just spining what's wrong if the starter's just spinning?
no installig a starter wrong will not cause engine knocking. all that will do is maybe short fuses, heat up wires, ruin your starter, or melt wires. knocking isn't electrical it is mechanical like lifters, pistons, valves, things like that
Check the wiring at the starter. Some fords have a power wire there, if it breaks or comes loose these problems can occur.
No,there is no circuit protection between the battery and the starter. If the starter is causing a dead short to ground, there is definitely something wrong with the starter. Pull it and have it checked. The switch that engages the high current is inside the starter. If the starter is fried and perhaps something melted to ground, every time you engage it you will get a dead short.
Starter has no voltage or insufficient to turn engine, possibly bad solenoid or something wrong with connections.
Broken starter drive? Broken tooth on converter/flywheel?
No. The coil has to do with spark to ignite fuel inside your engine. There is probably something wrong with your ignition system or your starter.
Never disconnect a battery while an engine is running!
Wrong starter, wrong fly-wheel, Bad starter drive, worn fly-wheel. Starter may need to be shimed.
Sounds like you need a new starter!
