My experience is you donot need to be an expert on the system, just have a general understanding of how it functions and use a logical diagnostic procedure.I have seen many times people just throw parts at a problem, battery going dead for instance, first a new battery goes in then an alternator and regulator problem still there so then it comes into the shop and it turns out someone plugged something in to the rear powerpoint and forgot to unplug it and a draw on the battery is the problem, 5 mins with a DVOM would have found a draw and a pile of money saved.
