Thanks Ralph, your speedy reply made my day. I went to Radio Shack and
purchased a package of 4 Rectifier diodes part # 276-1661. They will
work OK but now I need to hold down the C.C. button to hold the coil on.
I’ll work it out after a bit of effort. It’s so hot today that I felt I
should stop everything and let you hear from me promptly. You are an
excellent instructor and I thank you so very much. The way you write in
plain language makes things so clear to me. I thought I understood
every little detail until I got to the tractor and then became confused.
I missed an important step in connecting for coil holding. It felt so
good to listen to the motor hold a constant rpm and change as I moved
the dash knob. I will figure out some method to mark around the dial for
speed orientation points after I get the coil to stay energized.

Hi Raymon,
I used a Radio Shack diode rated at 4 amps @ 50 volts or higher.
Make sure the band on one end of the diode is away from the C.C. coil.
If it is on the end towards the coil it will not turn on the Alltrax.
Your diode should not be a glass one, they might not handle the amps
needed. If it is a black plastic one it may be backwards, that will not
hurt the diode, just take it off and turn it around. The foot pedal has
to be all the way up before the dash control will stay on. I had to put
a helper spring on mine to keep it from turning off on the bumps.

Ralph I have tried to copy your C.C. Button setup on my E20 as shown on
your web site page 5. I just cannot hold my foot still enough on my
rough lawn with only the pedal. I have installed a dash potentiometer
same as the one inside the box which is connected to the pedal and a
relay connected to the C.C. switch so I can move to dash control when on
the lawn. I have everything except the diode you show holding power to
Pin 5. Will you tell me what value to ask for and where to purchase the
diode? My replacement controller from Steve Richardson seems to be OK.
I occasionally get a red led flash but it switches back to green after a
moment or two. I just need the dash control to complete the job. You
know that my electronic knowledge is poor but my drive is strong and
unstoppable. I soldered an available diode onto a small phenolic board
along with the light resistor where Card 4 was mounted. My C.C. light
works OK but the diode was not right. Will you give me a hand on this?
Thanks, Raymon
