qUICK SIGNS ARE NOTHING WRITTEN ON TOP OF THE TALL TRANSISTER AND THE "REPLACES cHRYSLER pRODUCT STICKER. rUN IT hOT (HAIR DRYER HOT AND FRIDGE COLD) AND COLD TO SIMULATE CONDITIONS.
Oh crap caps lock sory!
Now, I'm not arguing here.....quite the opposite, actually. Looking for clarification. WHY is it "ok" to use the style resistors you say are "bad" for the ignition boxes on the instrument cluster voltage regulator? Lots of people have done that and they work great. Isn't it possible some of "that style" resistors....transistors.....whateverthehelltheyare are a good design? Help me understand.
