Remote DVA Peak Reading Tester Harness
Designed for use with 1978-2000 Mercury engines with separate
packs and ignition coils, Johnson/Evinrude 1973-2006 and Yamaha
engines. When connected to the ignition coils, the 15 foot harness
allows you to connect a DVA Adapter/Meter to the coils and switch
cylinders while the engine is cranking, idling or running at wide open
throttle. Can also be used to check trigger and stator voltages on some engines.
