Re: toro workman MDE intermittent drive
finally got round to looking at the the toro again and have found the controller some times doesn't power the accelerator on/off switch (no power from controller circuit good no breaks no bad earths)
the toro has a sevcon controller and struggling to get any info about them. would it be likely to have a fail safe in the controller ? im guessing I need to replace it ? I have attached the workshop manual for any one interested wiring diagrams start page 113 intermittent voltaged (0v-5v) on controllers main block point No3 |

Re: toro workman MDE intermittent drive
How did you end up going with this? I have a Toro Workman MDE also, and information on the Sevcon Millipak controllers is scant. It's a 633T46301 model, Toro part number is 110-2569 but triple the price. FSIP and Radwell sell the units but I'm not sure if they have the Toro programming in them.
I've pulled apart the controller but it is full of potting compound and will be almost impossible to repair. In my situation it's not powering the contactor. |
