hi all
just wired up my starter motor but when
turning ignition switch the motor turns but doesnt engage with engine.
any ideas please
cheers

Battery fully charged?
Electrical connections to the starter and battery CLEAN and secure.
Starter motor retaining bolts done up. (did that myself)
ALL earths between engine/chassis/battery clean and secure.

Just a few suggestions above.

Is it a solenoid starter or a centrifugal?...

What engine?

Check the solenoid connections first. If not, could you have a mis-matched starter i.e. the ring gear and starter having different pitched teeth?

hi
its a solenoid starter
all conections are new and good
its the original starter for the engine

could it be the solenoid itself faulty?

Take it off, put it in a bench vise (this bit important).
Wire it up and see if it throws out. I would suspect the solenoid first.

so start motor turns?

you later say it is solenoid motor - easily identify by a baked bean sized lump that is on the side of the motor.

this serves two funcitons:
1. closes contact to connect heavy current to starter.
2. mechanically pushes the starter dog gear on the starter shaft so it engage with teeth in the flywheel.

this is know as per-engage.

(without seeing you motor I assume the above to be the case as opposed to an solenoid whcih just makes the contact and the dog gear driven on the start - know as inertia type).

anytwas, back to pre-engaged. I think the movement of the are that pushes the gear also makes the contact so the gear is in place before the starter motor turns.

If you have wired up both correctly and the start is turning, the gear should be in place.

At this moment I cannot think what to suggest but to remove the starter (2 bolts to undo?)

and palce the whole assembly on a bench.

Test the solenoid first to see the arm is throuwn.

You can use DVM to check the contact is made for the motor.

You can check motor on tis own and finally power by solenoid.

Be prepared to see big sparks as you connect the batter leads to various parts.

Don't just put it on a bench, it will need clamping or putting in a vise, unless you want it leaping off the bench!!!!
