It rained yesterday so decided to have at the speed control.
Ripped out all the resistors and solenoids as well as the slider switch. quite a pile of stuff, may re-use it for our side by side tandem.
Connected all the leads last night and wow it seemed to work, the Pot Box needed adjusting as the spring on the lever pushed the lever to wide open. Had to rig a different spring. So finished up the install, had to build a few bits to link the go pedal with the pot box. Hopped on and put the tractor in reverse, ooooops motor ran , tractor went fwd, hah. put it in first and backed out of the shop, took it round the yard a couple of times in reverse going fwd. Back into the shop swapped the wires to the field terminals, and tried er again. Eureka, worked as advertized. Noted that it seems a little more powerful, much smoother, and very easy to control the speed, easy to inch forward, before it was hard to move less than 6" at a crack. Looking forward to increased range, tomorrow have to make the electronics weatherproof then get on with the stuff am sposed to be doin.
