I might suspect the pickup or the tci, if the problem wasn't dependent on the brush. In the center of the schematic there's a 10 amp fuse. If the voltage there stays the same brush or not then the brush isn't having an effect on the tci. And the pickup is a different circuit. The pickup can be broken but what you do with the brush won't change it
From what I've read and my own experience when a tci begins failing typically the engine stumbles or just shuts down but you can immediately restart it and everything will be fine again for awhile.
the TCI box, but generally they work or don't correct?
