My truck has a frame mounted circuit breaker mounted inside the frame near the starter. My metal covered compressor discharge hose fell down in between the motor and the frame while I was redoing air lines and it shorted out on the breaker and started smoking. While this is a unusual occurrence, I think there should be some sort of cover on the breaker. Can anyone that has a pete 359 or 379 check to see if there is a cover present to avoid shorting out? Since this is direct from the battery, a solid short could cause a fire. Seems like a strange place to mount a breaker anyway, down in the grime and grit. I would have had it up on the firewall if I was the engineer in charge.
