I just bought an Allis D17. I know it runs well, because I drove it around 45 miles to get it home. It was a pleasant drive, but the last half hour was a little tough since the lights dont work, and I ran out of daylight. Anyhow, I got it home and put it right in the garage to fix the lights. Someone cut all the wires near where the headlights are mounted, near the radiator and the real light as well. I was able to run my jumper cables to one light and to the battery and it lights up.
One of the first things I found, is that the fuse holder on the dash was broke. Jumping across that fuse holder made the little light on the dash light up. But no voltage to the headlight wiring, with the light switch pulled to ON.
I'm not 100% sure if the headlight switch is fed off that fuse, but I would suspect so.
So, it appears that the light switch is bad, because the wires near the headlights have no voltage, even with that switch turned ON, and the fuse holder temporarily bypassed.
I'll replace that fuse holder, and the switch if needed. But I have no idea what size fuse is supposed to be used. Can anyone help with that???? (My guess would be a 15A or 20A).

Ok, enough on the lights, that's a relatively easy fix, once I can trace the wires. I also know the starter solenoid is weak, and dont turn the starter on the first try, so I'll just replace that too.
But another question. While looking for a wiring digram online, I noticed that many times the SERIES of the tractor is mentioned. It appears there is the regular D17, and series 2, 3 and 4. How do I determine what series I have? I assume it involves the serial number tag. WHERE IS THE SERIAL NUMBER TAG located?
----
Lastly, about the Positive ground
I've never owned anything that had a POS ground before now. I know enough about electricity to know that the circuits are wired the same, just the polarity is reversed, and that lights and motors run fine with either polarity. (But NOT electronics, such as car radios or electronic ignition). But the D17 dont have electronics, so the only thing involved is the generator which must be correctly polarized.
However, someone told me that you can NOT tow or pull with a NEG ground vehicle, if using a metal tow strap or a chain. In other words, the tractor has a POS ground, and my truck has a NEG ground. So if I use one of them to pull the other and use a metal chain, something will be damaged in the electrical system on either the truck or the tractor (or both). This has me puzzled. In some ways it makes sense, but in other ways, I never heard of such a thing. How true is this?
Thanks
