Squealing like a pig now.

[AMC RULES 36,945]

Charged the new 1075's battery up overnight, then put it to work around here this morning. 
Got maybe 4-5 good starts out of it before, out of the blue, this happened when trying to restart again. 
Was originally trying to turn over, before ending up with a squeal...then just the squeal, and no turning over at all. 
I'm not an electrical kind of guy...so, I'm gonna need some expert electrical advise to help me fix this issue.

What's the voltage at the battery?

[squonk 38,936]

Me tinks either the battery is toast (low voltage ) or the voltage drop thru the switch /wiring is excessive. I believe the pig you hear is inside of your Genny.

[squonk 38,936]

Craig, check the battery voltage at rest and then again when activating the start windings. If it drops below 10 at crank, try another Battery. If it stays good and high try rolling the motor by hand and trying it again. Possibly a bad spott on the Genny commutator. Or bring it here and I hang on to it for a few years!

   I'll will check it, and report back with my findings. 
BTW...did notice it does have a non factory/replacement switch ignition in the dash.

Does the motor spin by hand freely?

[squonk 38,936]

Craig, The more I think about it I bet it's a low voltage issue. I think the squealing noise is coming from the regulator. I think one of the coils inside it is trying to pull in and can't because of not enough juice. Same thing as a solenoid clicking.

Standard stuff.

Put the video camera down and pickup the multimeter.
Start by measuring battery voltage

​It is a funny sound for sure but I'm not sure which "solenoid" in the regulator would be chattering.

The voltage relay doesn't activate unless the gen is producing over 14 volts - and that's not happening.
The current solenoid doesn't activate unless the gen is producing too much current - that's not happening.
The cutout relay doesn't close until the gen produces over  10 -11 volts and that's not happening.
Welded contacts the cutout relay could be draining the battery charge back thru the gen field coils ??

Be interesting to see what the issue turns out to be. Without a multimeter (or even a battery charger) we are all just guessing.

The multimeter will tell the story.

Well I could be wrong and totally off base with Craig's problem but As a teenager I had a 61 Ford with basically the same set up. I had bad spot in the Gen. that would feed back and make the regulator hum and squeal with the key off. Replace the Gen and the problem was gone

[AMC RULES 36,945]

To my ear...  
the squealing does sound like it is coming from the gen. 
Also found that if you just bump the key, not hold it, it gets past that spot, then starts right up with no issue. 

[ipperwash 74]

Have you checked the belt tension
 

[shallowwatersailor 3,213]

That does sound like a bad spot on the commutator causing resistance, hence the squealing. Especially if you can bump it. You may be able to pull the brushes and clean them without disassembling it. At the same time get in and wipe the commutator.
 

[squonk 38,936]

I would still check that battery voltage and also do a voltage drop on the cables. Could be  a combination of things lowering the voltage enough to cause an issue.

troubleshoot as a no start issue, don't worry so much about the noise.

[AMC RULES 36,945]

...and then this happened, and definitely made it a no start issue.

[AMC RULES 36,945]

Found the hot coil also caused...
a no start issue within my ignition swith.

Lucky the dash didn't melt.

[Wheel-N-It 2,967]

On my K series powered tractors I always remove the key from the switch after turning the key off. Typically I then lay the key on the hood of the tractor. I made this a practice after leaving the key on and heating the coil. Luckily I did not overheat it but it was getting warm.

[AMC RULES 36,945]

Had to get up, run back out there, and do just that yesterday Van. 
Guess that's why the PO had the STOP key chain installed.

You'll probably think about this situation everytime you get near your tractors Craig. I know I do. I was so relieved to have not damaged anything when that happened to me. It was on a KT-17 series 2 engine. I sure did not want to buy one of those coils. Too much $$$
