I have been having issues with my Montgomery Ward, after repairing a connection on the starter generator now all I get when I turn the key is click, the battery voltage is 12.7v on a multi meter, and there's 12.4v at the starter generator, this one has me stumped, help!

Imagine a wire with 24 strands in it. If one strand made contact, you could measure full voltage, but it would not pull a full load. Multimeters don't tell the whole story. Power is half the story, how's your ground wire and connection?

Ground is decent, cables are have a little corrosion at the ends, I have heard of cables corroding internally had thought about making new ones, also when fixed the connection on the starter generator the terminal did turn in the starter generator housing, could that possibly be the culprit?

Could of ripped a wire off the bottom of the stud inside if the stud turned.Had that happen a few times .It's a pain in the butt to fix because the wires are usually pretty short to begin with.

 

marked where the wires usually come off in Red.

That is most likely what happened as nothing else has changed, wonder if I could use the one from my case 210(Kohler 241) for the weekend so I can take the tractor to a show, they look Identical.

If rotation same no problem. If it bolts up.

I'm guessing those wires are soldered on too?

You can take a pair of jumper cables and imitate your battery cables. Hook the pos. and neg. clamps on the battery. Ground the other black end clamp on the engine. Touch the red end clamp to the "A" terminal on the starter generator. You have in effect replaced your battery cables. If something works now that didn't before, you have a bad battery cable. Now to determine pos. or neg. defective. Remove the black cable from the battery. If things still work, you have a bad pos. wire. Now switch. Reconnect the neg. and disconnect the pos. If they work now, using the key switch, you have a bad ground.

Yup, that wire is broken, just long enough that I can fix it with a drop of solder.0601171111.jpg

Just make sure it doesn't short out on the brush holder. It's pretty darn close.1 frayed wire and bye bye voltage regulator.Voltage regulators are the weak part of the charging system.

 

I would pull the whole thing apart and shoot it down with brake cleaner.And grease both bearings while it's apart. You can re pack the small sealed bearings pretty easily. Take a Pic and pop the cover off 1 side of the bearing and press new grease in with your finger.I've done a few.

Update, have had the one from my case on this tractor for a while but it's weaker than weak. Think I have this one figured out.0704172259.jpg

Update, starter generator reinstalled on tractor, New battery cables(with the exception of the one to the starter), new battery, crank over a few times, now no spark, then starter hangs hangs wide open setting off mad scramble for wrench to unhook battery cables, this is with the key turned off! Thinking either key switch or solenoid any thoughts?

Figured it out, solenoid is junk and points are bad.
