added slave solenoid in case there was a problem with the high amperage connection in original solenoid.

the starter spins and hits the the flywheel with a good clunck.

the side panel is easy. It is the panels for the air cooling that cover where I think the engine # is that seem to need some extensive dismantling. That's why I would like to know where to go looking for the engine #.

When the starter is unmounted and just lying on the wheel, it should leap as it is energised. It doesn't. That must mean that there is a voltage loss somewhere? I still suspect the braided cable between the solenoid and the motor.

Then hook a jumper cable between solenoid and starter and see what happens

With that ^^^^^^^^ and the fact it clunks into the flywheel, Sounds like the issue is within the starter it's self. A tear-down inspection is needed checking the brush and brush lead condition/rotor windings and bushing condition, Also check the plastic engagement fork for wear.

If all looks/checks good, Clean- lube and reassemble then replace the starter mounted solenoid. There's a plunger inside the solenoid that when power is applied the plunger lowers raising the drive assembly, At the same time it lowers it makes contact with the two large cable post on the bottom. Over time these plunger contacts burn up and cause a voltage loss to the starter motor.....

stripped down starter, again. no sign of any wear or damage. Motor only done 250 hours. There is no resistance anywhere. Possible problem with cable posts in solenoid has been by passed by installing slave solenoid.
We are talking MTD Cub Cadet Series 2000, spec PS45509BA, ser no 3133900791. Can't see engine no, but it would probably start CH16S

Please explain how/where you wired this "slave solenoid" onto the unit.....

OK, Do me one more test.....

Put your multimeter on the braided starter motor cable lug then post the voltage reading while trying to start.

Have you turned the engine crankshaft/flywheel by hand ?

Does the starter even try to turn the engine ?

Another "quickie" electrical check:...Put voltmeter leads directly across the braid wire you suspect...doesn't matter which color lead...look for a voltage reading "while cranking"...should be zero or close to..If you read a voltage, then suspect wire is showing a resistance, and thus a voltage drop..starving voltage to the starter..

When all else fails dip that starter in diesel for a few seconds and shake it off and re-install. Or don't but you got nothing to loose for trying. Don't sissyfoot it either, dip it right on it there.
