My alternator warning light came on a couple of weeks ago. I checked the base battery voltage (engine off 12.5V) and then started the tractor and measured the voltage (12.5 V). I replaced the factory alternator on my '82 Ford 4610 and decided to replace the voltage regulator also. I installed the new voltage regulator on the new alternator and ran the same voltage check. Engine off I got 12.5V and engine running I got 17.5 V. The voltage regulator was supposedly adjustable but when I tried adjusting it, it stayed at 17.5 V. I suspect the voltage regulator is bad It is a Transpo M5-152A, the same as the one that was on my old alternator and the regulated voltage should be 14.2V. When installed originally, the old alternator ran at 14.2 V with old voltage regulator.
Is there any reason that the new alternator would not be regulated to 14.2 V ?
