How to Repair a Couple of Wiring Harness Problems

BTW, small aricraft form the 50's, 60's, and 70's used ammeters with good reliablity. No reports of frequent fires and palnes falling from the skies. But the quality is no doubt higher. And most/many folks don't know how to read them for diagnotic purposes...but then again, most/many folks don't know how to read a voltmeter for diagnositcs either!
