As I continue to work through my SLT1554 to get everything running correctly, I came up with some questions around the voltage regulator.

I replaced the PTO on the tractor (old unit was trashed) and in the install instructions for the new unit, it is explicitly stated that voltage going to the PTO at full throttle needs to be 13.4-14V. So I check at the battery and find 11.4V. Then I move to the voltage regulator:

- 46-47V AC from the stator
- 11.4V DC from the output (B)

Based on what I was able to find, 46-47V AC is ok so I thought I had a bad regulator; about everything else electrical on this thing was bad, so it did not surprise me. I plug a new one in and get some improvement (12V) but no where near 13.4V+.

Now I'm digging around trying to figure out why I'm only getting 12V DC at the regulator output at full throttle when it should be higher. I found several posts across several forum boards that a bad ground may be the problem, or in my case, no ground! Sounds like the body of the regulator should be grounded but there is no wire or strap for mine. I could easily make a wire to run from the regulator screw to the Neg. terminal on the battery, but wanted to make sure this is worth my effort! I would also appreciate it if someone could tell me if the values for the stator are good.

Thanks!
