Welcome to HT Farmer,
You state won't tie, here is a question or two: Does it start on bale? Does twine arm move or not? Are you speaking of auto tie only (does it tie manually)? Has it ever worked for you? Realize I know little about your model of baler.
Yea, I'm looking for more details, but have no answers, but there are some folks on here that might be a much better help. Give them all the details of what is or isn't working or that you have tried.
One important thing is usually, if you have a requirement to use/need the tractors electric power, go right to battery, seems to be the best.

Loosen the twine tension plates so the twine easily pulls through the tension plates. Look at the end of the twine tubes. You could have either plugs at the end of the tubes or two flat springs inside the end of the tubes. If you have the plugs, look for grooves worn into the end of the twine tube which would allow the twine to pop back up the twine tube. If you have the flat springs it will be more difficult to see the groove in the plates, not the twine tube, because the groove will be small.
If you have grooves in the end of the twine tubes, switch the right twine tube with the left twine tube. The twine will now be wearing on a new surface.
If you have the flat springs inside the tubes, you will need to remove the tubes, drill out the pop rivets and install new flat springs. The flat springs are a thin plate with notches in the end.

The tension plates are as you say. The other items to check are in the end of the twine tubes where the twine exits.

Feeding hay helps the twine start. Make sure the knives work independent of each other and the knife edge sets on the striker plate for most of the knives length. The knives are not perfectly straight. If the end of the twine is just balled up, I would leave it alone. If the twine is stringy, then you need to do something.

If you're tripping it manually you can slow the engine down, get on your knees and watch what it does. You should be able to see if it's an issue with twine or maybe something else causing it. On my 648 the spring loaded bullets at the end of the twine arms were too tight and causing it to not put the twine on, you can loosen those up but they still need a little tension to hold the twine. Loosening those and the tension plates solved my issues, good luck.
