View Full Version : MDC guage controller, keeping all gauges on with KO

04-06-2009, 10:22 PM
I installed a new MDC, part # 6607-20009-01 H, old number was an 6607-20007-01 E along with 02' silver faced madallion gauges. Do to water ingress of old MDC. All quages work with KOER, but stay powered on with key off or even out of the ignition. The module seems to make the ign. side(purple) of the igntion switch hot at all times. Are any of you guys MC parts guys and can tell me if the 07-01E superseds to a 09-01H? Or do i simply have the wrong MDC? The boat is a Borg Warner style guage 99' 205v w/injected GM.
