My 1999 270H with 48” deck is having an issue getting power to PTO. Checked PTO with jumper to battery and it worked fine and I’ve actually been cutting grass using the jumper for awhile. I checked power from PTO switch to PTO and there is none. I checked PTO switch and it appeared OK but I replaced it anyway and still no power to PTO. Then checked brown/tan wire leading to switch and there is none. Could the issue be the NMIR module and is there a good way to check it. If bad, where is the best place to get a replacement and do other brands/models have NMIR a modules I can use. Also, would suppling battery power directly to PTO switch and bypassing NMIR result in switch working.
