Look under the car at the Starter. If you just have the main heavy gauge cable going to the Starter, the answer is no. The Starter is spinning and the Bendix drive is bad.

If you have Solenoid wires in addition to the heavy cable at the Starter, you can try to jump the Solenoid under the car at the Starter. If the secondary wires (small) are not providing power to the magnet that throws out the Bendix, jumping power to the magnet will make the Bendix work. You do not want the Bendix to stay engaged or you will damage the Flywheel or burn up the Starter. You might as well check the Secondary (small) wires for corrosion because the problem is outside the Starter.

If the contacts for the magnet inside the Starter are burnt, jumping the Terminals will do nothing.

Changed solenoid now the starter keeps spinning even with key off. Can the 2 smallest wires cause this. The 2 large posts are right

very possible as the solenoid will be constantly engaged if one wire goes to ground rather than through the ignition switch

Starter clicks but will not turn engine over on 2004 Dodge Durango. New starter and battery.

Hi Mark
Sounds like you are doing all the right things.
We used to Load Test a Starter Motor by putting it in a Large Vice and connecting a known good battery with solid fat jumper leads.
When the solenoid throws the cog forward to engage we would use a 2 by 4 block of wood levered against the cog to try and stop the starter from spinning. The wood burns up under load but it quickly proves the Starter is functioning under load. Without using the engine.
Also you could try removing the spark plugs on the engine to allow the compression to escape. Make sure NO sparks around to ignite any fuel vapor.
The engine should spin over easily like this and you can hear & see if anything is binding up.
Hope this Helps!
Good luck!

What would make the starter engage when the key out of the ignition

Your problem seems to be a faulty solenoid. The solenoid is a little monster that lives on top of the starter motor, and its job is twofold. Firstly, it supplies full battery power to the starter motor, and secondly it drives a gear on the starter to engage with the engine flywheel.
Now, your problem. The first guess could be the ignition switch, but fitting a toggle seems like a fairy tale answer. Check the starter solenoid to see if there is a frayed wire on the thin wire that connects to the starter, or possibly a frayed wire on the battery cable that is shorting to the small connector. Otherwise, I have seen the terminal of this small wire actually become loose and turn in the direction of the battery cable, which is also connected to the solenoid. A short here will cause the problem you are describing.
Finally, the solenoid could have a short circuit inside the body, which means replace the solenoid.

well since the starter was only 2 months old i am betting its an ignition short. When u turn the key, the solenoid on the starter engages the bendix gear with the engines flywheel and then energizes the starter motor. And when u release the ignition the solenoid and the starter motor should de-energize. hope this helps you.

GMC 6.0L starter does not engage

To check the starter: key off, transmission in park or neutral, brake set. Pull off the small wire to starter solenoid. Then use a small jumper wire from battery cable post on the starter to the solenoid terminal (can also use a small screwdriver to bridge those terminals). Starter motor should engage the flywheel and spin the engine. If nothing, starter motor or solenoid is bad. If starter works, check for power on the small solenoid wire, with key held in crank. Wire should have power, if not, check start circuit from ignition switch to solenoid-the neutral safety switch is in that circuit.

Starter activates when battery wire connected and starter is grounded to frame with or without solenoid wire connected. No short between posts on new starter. Only does it when the power source is from the...

sounds like you are hooking up the starter wrong. the positive goes to the starter main terminal from the battery. the ignition wire goes to the s on the solenoid, which activates 12 volts when the ignition switch is turned on which causes a magnetic field
inside the solenoid and joins the connectors
in the solenoid to the main positive wire from the
battery to the main starter unit brushes/armature inside the starter unit. If you have a constant
12 volts from the ignition wire it will keep the solenoid engaged. If you put the main positive wire on the wrong solenoid terminal it will immediately engage the starter. try putting the main battery wire to the correct terminal or perhaps check the ignition wire for a short or constant voltage to the solenoid.

1992 jeep yj will not turn over

Try jumping the solenoid,pull the actuator wire off the solenoid(the small one)This will engage the starter so make sure your in nuetral or park,run a wire from the solenoid actuator to the positive battery post,if the starter engages your ignition switch or starter relay have become faulty,if the starter does'nt engage the solenoid has gone bad.Post back if you need more help.

Truck want start

It may be your starter solenoid. The ignition key only engages the solenoid not the starter itself. If the solenoid is jammed it wont engage and switch power to the starter motor. you can easily check this by locating the heavy cable lugs on the solenoid (a metal tube about 1.5 inches in diameter normally mounted on or next too the starter motor) and shorting them with a wrench. You will get as spark but the starter should spin. If this happens you know it is the solenoid that is the problem.

You can sometimes free a stuck solenoid by tapping it gently with a hammer. However a more permanent solutionis to take it off and clean it, It may be jammed because the steel core is jammed in the coil. Fix this by cleaning. Otherwise the electrical contacts at the end may be damaged or dirty. Clean these up and make sure they contact properly. Use electrical switch cleaner.

Good luck

Ignition problems

Hey there Krabbe,

Since you are considering changing the ignition switch, I'm going to assume an above average mechanical ability on your part.

Sight unseen, I'd check the starter and solenoid first. They are easy to prove/disprove as the problem. The procedure for replacing the ignition switch is much more involved.

The solenoid on a Ford is usually near the battery and easily accessed. It has two heavy cables and a thinner gauge wire attached to it.

Before doing any testing, make sure the transmission is in Neutral or Park with the Parking Brake on.

Applying +12V to the terminal the thinner wire is attached to should engage the solenoid and cause the starter to crank the engine. You can use a small jumper (alligator clip type).

If the starter engages, you were right. Next stop the ignition switch. I'll get the replacement procedure written up for you.

If the Solenoid gives a solid CLICK, but the starter doesn't spin, use a screwdriver to short the two heavy solenoid terminals. If the starter spins up now, the solenoid is the problem. If not, it's the Starter.

The way we proceed depends on the results though. Please respond with what happened with the test. I'll get you going.
