Starter solenoid help

Im having a bit of trouble with the starter on my International 244. When i turn key nothing. I jumped the solenoid posts and the starter turned but gear did not extend. I purchased another solenoid and its the same. Can the new solenoid be bad as well? I didnt think it was the starter because it turns when it gets juice. Stuck,Thanks for any advice.

If it does not engage but spins it is one of 2 things.

Not enough juice, or a bad starter.

I'll ad two ideas.
If your starter is a solenoid type with a mechanical link to the drive gear (a plunger that attaches to a fork which pulls the pinion into mesh with the ring gear), the jumping across the big terminals will not make it engage the gear.
It is necessary to jump from the battery cable terminal to the small terminal (usually has an S near it) to make the solenoid operate.
Without this, the starter motor just spins.
If your starter has a Starter Relay (not technically a solenoid) it will have two large electrical connections, and (probably) 2 small.
One labeled S the other I.
Jumping across the two big terminals of this relay should make it start (with lots of sparking.
Jumping from the battery cable terminal to the S terminal should also work. (much less spark)
If this type just spins the starter. Either the battery is weak and not slamming 100% effort into the drive, the Starter motor is dragging pulling high amps but internal friction from rubbing parts is preventing it from spinning the drive fast enough for engagement, or the drive is sticky and not spinning out into the ring gear.
Let us know what you have going. JimN

Your Bendix drive needs to be replaced. Hal

Here's a Bendix drive yours may be similar. Hal

Sounds like insuffient voltage. Try putting #2 or #1 Battery cables on your battery and see what happens. Cured my slow turning starter like magic.

Thanks for all of the responses. There is a small clip type terminal on the solenoid. If i ground this from the battery directly then the solenoid retracts. This is leading me to believe that the solenoid is always hot and that turning the key grounds it enabling it to activate. Trace wiring back to key? Could there be a bad ground? I should also add that when i crossed the two bolts it engaged SOMETIMES. something like every 15th jump gave me a steady crank of the engine. BTW there are no markings on any of these parts(-+).Thanks

Yes the starter is a solenoid type with a mechanical link to the drive gear (a plunger that attaches to a fork which pulls the pinion into mesh with the ring gear. Im going to look at it right now and will post shortly. If this is the case, what would be the next step? Key switch needs replacing? Thanks

If nothing is broken it may just be gooped up with dirt and congealed grease so that it can"t pull in. Take it apart, clean it, and relubricate it. If the starter spins the key switch is fine.

Another possibility is a bad spot on the ring gear.

Does small terminal located on the solenoid get pos or neg off of the wire? Im assuming that wire is direct from the key switch. Im measuring 9 volts at that terminal and 12.5 at the solenoid post coming off of the battery.

Your one small terminal on the solenoid should have battery voltage all the time. The other S terminal won't have voltage. This probably feeds voltage to your starter switch and when you push a starter button or twist a key voltage will flow to the S terminal on the solenoid and the bendix should engage the ring gear and crank the engine.

You need to have good battery cables and all connections clean including where your battery is grounded. You need a fully charged battery too.

You can check for voltage using your volt meter to see if there's voltage at the S terminal when
the starter button is depressed or when the key is twisted. You will need a helper. When you jumper across both of the small terminals you're bypassing the key starter or starter button. You need to trace those wires off the small terminals on the solenoid. Use your meter. Hal

Okay. I believe i fried the solenoid. I was grounding the terminal to turn engine over. Gonna order another one. In the meantime i traced the terminal wire to the key and going to start troubleshooting that there. Im learnng.

On two H's, I've suddenly run into a no-start situation that sounds identical to yours. After testing down the starter circuit component line, both were resolved by replacing the battery cables. I wouldn't have believed it to have such a dramatic change (from starting fine to nothing) but the resistance built up in the old cables was the culprit.

Please let us know what solves it.
