I'm reading in the book about how to test ignition parts in the big red pig. It says I need a "Peak Voltage Adapter" to plug into my multi-tester. Of coarse the book throws a Honda part number at you, (which are always over-priced, POS tools). Are "Peak Voltage Adapters" commonly available? and where? I have a friend who is an electrition, and an uncle who has been in electronics repair for a long time, and neither of them have heard of a peak voltage adapter.
