Hi all, Thanks for the responses. The direction to the ET list has been informative. I have some experience (but no formal education) with EVs having converted an S10 (120v), a couple of Allis Chalmers G tractors (48v) and a Ford 9N (120v), not to mention maintained electric golf carts and the like.
The ET tractor was very rough when I pulled it out of the pucker brush. I had no interest in restoring the original controls so set about preparing to use a cheap knockoff of a "modern" Curtis 1204 controller with Li battery. After reading thru the ET list, I've decided to keep the F/R solenoids on the armature and use the field windings speed control. (Some golf carts were set up differently) That is, unless someone has a good argument to the contrary. I'm not an EE so if someone has words of wisdom regarding this, I'm all ears. I did put new bearings and brushes in the traction motor and all 3 mower deck motors and freed up the brake! I also come up with an obvious answer to the issue of providing 18v to the front implement motor.......use one of the several Makita 18v batteries I have around the shop. Much simpler than trying to tap the Li battery and unbalance the cells. Thanks for your help and inspiration over the years. Once the ET is on the grass, I can go back to getting the Solectria Force and the Solectria E10 on the road. cheers, John M "Money is like manure; it's not worth a thing unless it's spread around encouraging young things to grow."
