CUB IS CHARGING!!!!!!!!!!

Well after I completely rebuilt the wiring harness and cleaned everything that I could remove and clean the cub started charging.
It charges at about 9 amps above 1/2 throttle. It seems to maintiain this rate of charge all the time. When I turn on the light switch to the "D" position it discharges by about 5 amps. When I turn it to the "B" position the ammeter runs about at the 0 position.
Is this correct for the tractor?
Thanks.

Not quite yet. But a great start. (no pun intended)
The cub should put about 7.2 to 7.4 volts into the battery when the engine is running fast, and tha battery is fully charged up (with a small charger on 2 amps, overnight). The voltage is most important. If it is not, the regulator needs to be adjusted to charge more. If it is at the volts above, it should never discharge at high speeds when the lights are on. D or B JimN

I have a digital volt meter and when I touch the battery posts with the leads the VM goes crazy and lights up the entire LCD screen.
I have hooked it up to my C I have and it reads fine. what would cause this problem. This problem occurs weather the tractor (cub) is running or not.
About the discharge when the switch is on "D" could that be the resistor wire causing the problem?
I used the VR from my C to get the cub charging.
Thanks again.

The biggest difficulty with a digital VOM is that they sample voltage, and report on the sample. If done 300 times per second, you will get 300 different numbers from 0 to 30 volts. Your tractor and VR are very noisy in radio frequency interference(RFI), and there is not much to cure it except a modern alternator, and wire wound magnetic suppression plug wires. The digital meter trys to see this as AC, or static, or just looses control of all attempts to indicate. (yours does) A cheap analog gauge (needle type) is the answer. Pawn shops have many Tripplet, or other brand of good meter cheap.
If the lights on dim "D" discharge more than when on B, the resistor may be shorted to ground inside the box. A resistor in line (series) always reduces the current in a circuit. Headlights on these tractors have only one filiment, and use a resistor to drop the volts to about 4 when the circuit (dim position) Keep us posted, JimN
