I am replacing the original alternator on a Yanman 140YM69 (bad bearings) with new HAL-1215 alternator. Orginal wiring on old alternator had 2 wires wired with wire nuts no plug to tractor wiring. I installed new alternator, then with tractor running I now measure 25 volts AC at new alternator. My question as this is AC volts , I assume polarity should not be of concern when connecting to the tractor wiring? The other question is the 25 volts normal at a high RPM of tractor it looks pretty constant even when RPM reduced? Wires travel to what is shown on print as a current limiter. Any advice would be appreciated. I am trying to be a little cautious here before connecting wires to current limiter. Thanks

25 volts AC? on 12 volt DC system, not good, your voltage regulator is probably the rectifier also and not working or bypassed. you will smell the battery and eventually fry it with AC voltage, your alternator is full fielding at 25 volts,
Hope this helps ....

His dynamo puts out ac voltage, the regulator/rectifier changes it to about 14dc volts. Don't think he wanted to hook up the regulator until he was convinced it didn't make any difference which way the two wires hooked up. ....
