Voltage output from johnson stator

[jy118lfd]

I have a 83 150 crossflow does anyone know the max output from the stator in voltage? I know that the amp output is low but it makes like 15+ volts at higher rpms. My tach does not read right and I have a replacement but I don't want to damage the new one if this is bad. I have a new rectifer coming cause the old one has a couple of bare wires and I dont want to get stuck if they corrode. Is this the regulator or is there a seperate regulator? Thaks to all!

Yes there is a seperate regulator. <br /><br />When you say the tach doesnt read right, we assume that it did at some point and no one has changed the tach setting. Correct?

The tach setting is on the 12 pole setting but I had a post earlier about max rpm being 4200 wot at 42 mph with a 21 pitch prop. this equals 6% slip so I don't think the tach is right. I have a new teleflex tach that has a setting for outboard alternators setting 6 is for johnson according to the back of the tach. What is the max voltage output is 15+ to high it seems the more rpm the higher the voltage and it seems high to me
