Even simpler, these don't even have "glow plugs" they have one wire to the thermostart plug. It's in the intake and not each cylinder like glow plugs.
Yanmar 1601d electrical repairs worth it?

I was just looking close up at your posted picture of your regulator connector. 4of 6 look great. 1 looks ok. Then the one melted one, I would not wish to use, but bypassing just the 1 is easy enough to do with with 1 each of matching style male/female connectors.
Have you determined if you blow the fuse with your dyno unplugged?

Take your volt meter and check how much power your putting to the battery. With the Regulator smoking there a good possibility that's the problem. If your putting 13.5 etc. to the battery your most likely in good shape on the Regulator & Dyno.. Rules that out! Then start checking the wires and connections to the burnt Circuits and blown fuses. Your find the problem.

With the regulator smoking and the melted connector, his problem is like in one of the 2 either the dyno or the regulator. Off hand I am not sure where the melted connector point goes to. If it is from the dyno to the regulator his problem is likely the dyno. If it goes to his fuse that is being blown,his problem is possibly his regulator. But that wire being shorted out may be the problem as well. A voltage test, ohm test as well as close visual inspection is in order.

You can be over charging and it causing the Circuit problem and blowing fuses etc.. You need to check How much power you sending to the battery. If your over charging your going to be blowing fuses and you have to rule that out first. If it checks out good move on the wiring.

Is the OP even here? Seems like we lost him awhile back?

He had previously stated he was not very electrically inclined. These ym yannies are so simple on there electric systems that if taking down to one circuit at a time a basic understanding and he should be able to proceed.
But I fear the varying opinions expressed, may have scared him off.

Not scared off yet! Just busy with work and family.
I had to replace the brakes on my daily driver and stocking hay and building hay feeders for the winter in my limited free time.
I did spend some time with the tractor today. I still have not replaced the voltage regulator, and it is disconnected currently. Here is what I can report (forgive me if it is obvious to the more inclined):
1. Dyno connected, the key turned to "on" but not starting the tractor =blown 5amp fuse.
2. Dyno unplugged, key turned to "on" but not starting the tractor= blown 5 amp fuse.
3. Battery connected, dyno connected, but key turned to "off" battery reads 12.5+
4. Battery connected, dyno disconnected, key turned to "off" battery treads 12.5+.
5. Battery connected, dyno connected, tractor running 12.5+ and stable (checked over a couple minutes no change).
6. Battery connected, dyno disconnected, tractor running 12.5+ (checked over couple minutes same level).
7. Battery connected, tractor running, headlights on dyno dis/connected both, 12.4 but slowly falling.

I will have to think a little about that. But I can say for sure your not charging your battery. So either the voltage regulator is not allowing voltage or your alt/Dynamo is not working . Crank it back up and probe the outlet wire on the alt to see what the unregulated voltage coming out of it is.

OK, slow down,
First start physically tracing the wire from the 5 amp fuse.
It is blowing the fuse find and fix that issue.
The 5 amp fuse appears in the schematic posted earlier to only go to about 3 items.
Fix the short first, you can disconnect the individual components if the wiring all looks good.
Disconnect the first one install a fuse and turn on the switch if it holds you are good to that point,
reconnect after switching off go to the next component and repeat, once the short has been fixed then address the next problem.
Such as carefully inspect that over heated connector and repair or bypass that connector.
An English translation of that electrical schematic would be of great assistance in troubleshooting
