Sevcon Controller #633T45303 flashing a 4 code.

I have a Columbia Summit Series VIN 5FCLS46A161001181.
The Sevcon Controller #633T45303 is flashing a 4 code. After reading various threads on here and the manual I see there are several potential issues – Bad Contactor, Stuck Brushes or bad Controller. My question is for a weekend/shade tree mechanic which of these can I test without taking it to a professional? The closet Columbia dealer is an hour away and I prefer to avoid towing it to and from. Does anyone have a step by step of testing the contactor or cleaning the brushes?

Thanks,
Tom
