Hello, this is maybe not strictly an electronics problem but I hope someone can help me anyway.
I have a 12V air pump (runs out of the car cigarette lighter). It had worked ok the first few times then stopped working, with smoke billowing out of the receptacle while it was plugged into the socket. I opened up the receptacle and it was all melted inside. I replaced the entire receptacle with an identical one. The result was that it worked for less than a minute, smoke started coming out, the inside of the receptacle melted again. Reviews on this air pump from the store I bought it from showed this to be a common occurrence, along with repeated burnt fuses, etc. Except for one particular reviewer who seemed to have found a way around it with a mod as follows:
"...did not want to return the unit to get a replacement with the same cheap cigarette lighter plug, I simply cut off the burnt plug and replaced it with 2 strong alligator clips and an inline fuse receptacle and I now plug the unit directly onto my car battery's post. No more problems !!!!"
I guess I could just get a heavy-duty marine-grade receptacle, but I like the idea of just running off the car battery directly. This seems easy enough to do but since I'm no expert, I was wondering if anyone here could provide a little more detail on the above modification. What I would really like are pics of or links to the sorts of parts referenced to in the above mod so that I'm sure what to get. The fuse that was inside the original receptacle was 15A. Thanks!
