The reason for item 2 is in item 1.
Your shop teacher meant well, but unfortunately, he lacked the expertise to understand how wrong he was. Speaking as a 30 year electronics technician, I can tell you that inserting an ammeter in line is the ONLY way to know what current is flowing.
Simply follow my procedure and in less than 1/2 hour, you will know what current is flowing and where it is flowing. PERIOD.
Taking these lazy shortcuts wastes time. No actual technician who understands what he is doing measures voltage drop across a damn FUSE to track a fractional amp of current. MY SE's standby current is .015 to .019 amp. I can leave the car in the garage for eight weeks and it starts right up, every Crossfire on the road should be the same. I can even tell you where that .019 amp is going, because, out of curiosity, I have measured it. (PTCM, SKREEM, AM/FM head and the CLP/SSM together sink .018 amp.) Such precision by measuring voltage drop across a fuse is impossible.
Go measure the current and if you need help with putting a stop to the excess current, just post (tag me tho) and I will be happy to get you thru this.
Happy new year!
