Yesterday's mowing went into late evening, so for the 1st time I used the head lights. I noticed with the lights on the ammeter went full scale to the C side. Is that normal? Today I checked current draws and the battery voltage. At idle and full speed with nothing on the meter hovered around just right of 0 and battery voltage showed 13.8-14 V At full engine speed and the electric PTO engaged the ammeter went to about the 1st mark and battery voltage was 14.1 V. With the PTO off and the lights on the ammeter went a needle width past the 1st mark and battery voltage was about 14.1- 14.2 V. With the PTO engaged and the lights on the ammeter went full scale or pegged and battery voltage was 14.2 volts. Current draws I checked at the battery negative with the engine off. The lights registered 5.8 amps and the clutch showed 3.8 amps. Nothing getting hot and I did not find any chafing or shorting wires. I'm beginning to think it's just the range of the ammeter and it stays cool unlike the truck's which gets warm at full range.

It would be most helpful if we knew what model of Cub Cadet you are talking about.

What if the ammeter is just not super accurate ? I have a couple of gauges that show very little charge yet voltage is correct.

Based on those voltages, that is normal operation. Your ammeter may have gone bad.

Yup '70 mopars had a problem. Most of us bypassed them for better, reliable charging.

Yep, 70s onward onboard electrical systems got more and more loaded. I took this one apart. No apparent mechanical problem. Testing showed it's accurate on the D side, but overly sensitive on the C side. Had I known what I know now, I woulda just swapped conductors.
