The stator puts out AC and your VM will not read AC if it is in DC mode. You get AC from that stator and the voltage rectifier/regulator changes it to DC and then set the out put to 13.8 to 14.2 VDC. The stator out put at full throttle can be as high as 36-48 VAC. And in some cases higher. If the out put is below 24 VAC your stator is starting to go bad. I can take my Fluke 77 and set it to DC voltage and put the leads in a 120 VAC house out let and it will read nothing even though the out is live. Todays meters can tell the difference between AC and DC. Older meters could not. With todays meters you can test for AC riding on a DC line and DC riding on a AC line. This is good for when you are doing work that needs power filtering.
