(ET) PTO works, EGT150 won't go. No propulsion.



Howdy folks -

I am the new owner of an EGT-150 with a mid mount mowing deck and a snow thrower. I am so excited to be working on this machine!

I ended up with it, because I told a family member I would be exploring converting a john deere mower to run on electricity. He stumbled across this mower, and delivered it to me free of charge.

According to the former owner, it ran and ran well until it recently stopped charging.

I found one battery was at 2v, and have replaced it. 6 batteries are now reading 6.2-6.3 volts. I have not load tested.

Currently I can run the mower deck, but I can not get any propulsion. The wiring, contactors, relays, seem to be all factory. When I put the throttle into Forward, I hear a contactor click. When I pull it back to reverse, another click. Neither results in the tires spinning. 

So here are some questions:

  1. Where are the cards on this tractor?! I can't find a circuit board with capacitors on it. I feel stupid.
  2. How would I most easily verify that the motor is getting the volts it needs to kick on? I can't seem to read anything "back there" with my multi-meter, but I am hesitant to start ripping wiring apart until I've confirmed that the contactors are doing what they should be doing.
  3. I have ordered the electronic controller upgrade kit from Free Range Electric. Does anyone have a link to a good guide to putting that upgrade together? I am sure I can figure it out, after a fashion, but I'm a carpenter by trade, and I tend to take the long way around electrical issues.
Thank you!
