Sevcon Troubleshooting

Hey Everyone

Looking for some help on this unit. The service manual is very vague when it come to troubleshooting this forklift. It has a SEVCON control unit in it.

If you have any experience in this, it would be greatly appreciated.

Hey

I do work on these units sometimes. Are you getting any codes. Most likely you will see a code for Mosfet S/C. in my experience, it has been the contactors. Even though they look perfectly fine, everytime I replace them, the unit is back up and running.

Fact of the week
The black box flight recorder was invented by Australian scientist David Warren in the mid-1950s. While initially met with indifference in Australia, his invention gained international recognition, particularly in the UK, and is now a mandatory piece of safety equipment on all commercial aircraft.
