Hey guys, today my boss gave me his Snap-On EECT301A 12v Circuit Tester. He said it was 15 years old and that over time the wires eventually started to cross and he bought a new one ($85) http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=66995&group_ID=1390&store=snapon-store&dir=catalog". What's cool about this tester is it doesn't just tell you if a lead is hot, it also tells you if it is a ground where ass a regular tester wouldn't be able to to tell you if it is a ground or just disconnected. So while at job #2 (Radioshack), to my suprise I was able to disassemble it and decided instead of fixing the 2 blown LEDs, that I'd invest the $4 and recreate it.

 

 

I was able to fit my recreated tester back into the snap on assembly . You can easily create your own enclosure and probe with an antenna or cable.

 

Hope this helps someone
