I recently acquired a 26AE15AA that will not run and would like to get your opinions. I was told that the tractor did run when parked indoors many, many years ago. There has been some work done on this tractor in the past. From what I can see the;

- Key switch has been replaced

- Forward / reverse relay is a different unit completely.

- Card 1 has soldered connections for the wires now vs the slip pins and all the wires were cut and reconnected via a 15 pin AMP connector.

I performed some initial checks from the Home Owners Manual.

- Wiring looks clean

- Card components look fine

- Key works

- PTO works

- FWD/REV relay works

- All the microswitches in the speed control are good.

- Voltage from the speed control start switch is getting to Card 1 pins 5 and 6 as they should depending if start was actuated in forward or reverse. However the L coil does not energize. I applied voltage externally and the coil did energize. 

From the looks of things, this points to a Card 1 issue but I was wondering if there is something that I may have missed. Could the resistor card be a problem? Or doesn’t that have anything to do with the energizing of the L coil?

Thanks for your help.
