Current reversed on compressor spike controller

[Mike Betts]

Scott,

Last year's rules allowed you to replace the 20A fuse with a 20A self-resetting circuit breaker because everyone was having this problem.

The issue is that, as the battery voltage goes down, the current to the compressor goes up. The mechanical work that the compressor is attempting to do is independent from the drive system (or anything else) on the robot. If the mechanical power remains the same, the electrical power will remain the same (neglecting efficiency) and the current must go up as the voltage goes down.

Replace the fuse with a circuit breaker and move on...
