Troubleshooting Air Pump Failure

One second it was filling a tire, and the next, not so much. Join me as I work through some general troubleshooting to determine what failed.

Interesting! I wonder if you leave it on for a long time, if the fuse is suitable to protect the motor before it starts a fire. It seems suspect to me that the motor has a turn-to-turn short before the fuse opens; I think the fuse should be a lower value. However, maybe the windings are sufficiently small in the motor that the windings will open before any fire occurs. It is “attended use” and has a air gap switch, so I don’t think that would be “unsafe” per se, but it might be a fun “torture test.” What if you increase the limit to 11A so it wouldn’t trip the fuse (and, then you can make “this one go to 11”)? Nice breakdown!

Sounds like it might make for interesting video! Stay tuned! Thanks for watching!
