The ARM/GEN wire is still connected to the gen light wire, so you are getting a back feed through the gen light to the ign circuit, causing the light to be on when the tractor is shut off.. Find the GEN light wire, it should be a small wire connected to the GEN/ARM wire in the original harness at the old regulator. Remove it from the ARM/GEN wire. Buy a GM alternator repair plug kit from your auto parts store to plug into the "1 wire" alternator and connect the original little gen light wire to the #1 (usually a small white wire in the alt plug). This will give you a correctly functioning gen light and will excite the alternator at lower rpm. A real win win deal, as you get the light working correctly and get a quicker exciting alternator.
