Jd my wiring

So I got all new gauges cut out relay and wiring harness. I put everything the way it should go according to the manual. I also got a pice if paper that was numbered describing what goes where. But my ammeter is showing any charge. There are two letters on back of it that show ?L? and other side ?B?. But on the diagrams it does specify which one is positive. It just says positive. Didn?t know if this could be an issue as to why it s not working or showing charge.Maybe I had the wires crossed or backwards.

Do your instructions mention polarizing the generator?

The generator is refurbished. Sorry not new. Also I have no clue about polarizing it. I did go back through my wiring and forgot to tighten down a wire on the cut out relay opposite side of battery terminal on relay. How do you polarize generator. ?

Take a look at the [b:654c4848f0]Lamps and Wiring[/b:654c4848f0] diagram below.



Note that the electrical system is a POSITIVE ground system.

Current flows from the NEGATIVE post on the battery to the starter switch on the starting motor.

Current flows from the starter switch through a [b:654c4848f0][i:654c4848f0]<font color="#ff0000">RED[/i:654c4848f0][/b:654c4848f0]</font> lead wire to the ammeter.

Take a look at the ammeter on "Rusty" one of our 1951 Model Ms.



Hope this helps.

[b:654c4848f0]When and How to Polarize a Generator[/b:654c4848f0]

Polarization is a procedure which matches the polarity for the generator and the voltage regulator by permitting a surge of current to flow through the generator, correctly polarizing it.

Damage to electrical components can occur if polarities do not match.

Polarization of the generator should take place whenever any of the following events occur:
1. The battery is replaced or disconnected from the tractor
2. The generator is replaced or serviced
3. The regulator is replaced or serviced

If any of these events occurred, do not start the engine until polarization is done. The polarity of the generator must be set to match that of the voltage regulator.

Make a jumper wire (14 or 16 gauge) and put alligator clips on both ends.

Polarize the generator by using the jumper wire and momentarily jumping from the [b:654c4848f0]ARM[/b:654c4848f0] terminal on the generator over to the starter switch on the starting motor to get a small spark.

Take a look at the photo below of the jumper wire connected to the [b:654c4848f0]ARM[/b:654c4848f0] terminal on the generator on "Sparky" our 1951 Model M.

So what are the causes of starting tractor without polarizing first ?

Take a look at the following <a href="https://www.autozone.com/repairguides/Jeep-Wagoneer-Commando-Cherokee-1957-1983-Repair-Information/Engine-Electrical/Generator/_/P-0900c152802524f7">information</a>.

"[i:654c4848f0]If either the generator or regulator is replaced, the replacements must be matched for voltage and capacity, polarity and common manufacturer. If the components are mismatched, a loss of amperage capacity and/or damage to the generator will result.[/i:654c4848f0]"

Hope this helps.
