I've got a Campbell Hausfield hobby type compressor I won in a contest back a bit. Anyway been working fine, shut it off for a few months and when I went to use it again, no joy. (Fortunately I have a backup).
Fuse was blown so I put in another one. Bzzt! Hmm, let's try that again. BZZT! OK, there's a dead short somewhere. Got thing completely disassembled. There is no obvious fry or melt anywhere. The motor brushes, etc look fine no visible shorts, not even sure you could have one.
The only electrical components are the power switch, the pressure switch and on the PCB itself are a Metalized Polyester Film Cap 104K/630V and a KBPC1-10 Bridge rectifier. Oh and the fan leads, a standard 120V type cooling fan.
Now I am definitely not a real electronic gearhead. I can solder/desolder, use a meter and I sort of know what the components are for. So my question is could a rectifier fail sufficiently to cause a dead short without any external evidence. I'm pretty sure it isn't the cap since it's just in and out 2 leads, but the rectifier has 4 legs and from the data sheet I looked at I could definitely see where an internal short could develop.
And no I haven't metered anything yet, I just got it disassembled for the preliminary exam and wanted to ask this.
