i probably fried the new regulator...i am ready to set this tractor on fire, that is if it dosn't just burst into flames on it's own. my grass is getting tall. time to get the push mower out.

It sounds like you are confusing Amps & volts.. The dash guage displays Amps. If it is showing -5, it means you are discharging 5 Amps and killing the battery.
Have you load-tested the battery to verify it is good? Make it happen as a bad battery will defiantely cause your trouble.
Are your positive & GROUND wire connections Clean and tight? Another cause..
**Unhooking the battery and running the engine will fry
some regs depending on the type**
I don't know about 40V AC for the stator but I think the output should be closer to ~30-36V AC. Test this by unplugging the Regulator with the engine off
and then start the engine, get it to WOT and test between the 2 wires that come from behind the flyheel cover and go to the Reg plug with your multi-meter set to AC volts.
If it's below 30V AC theres a problem in Stator-land.. Investigate further..
To test the Stator 'short-to-Ground' theory offered above- The stator windings should be isolated from the engine's ground.. With the engine / key Off and the regulator unplugged, install a Test light connected to the battery's positive terminal. Verify the connection by testing to a known ground.. Test to the two stator wires from behind the shroud and if the light lights- You have a short to ground! Find it and repair it.
If not, plug the reg. back in and test the battery voltage with engine @ WOT with the PTO off
. If it's 13.5-14V DC it is working correctly.
If you turn the PTO on and the voltage drops below 12V DC you may have a bad electric Clutch or short in your PTO wiring.
Hope this makes some sense to ya!
