Hi everyone

The gauges on my 1999 cobia (CD206) are no longer working. no lights no activities, nothing at all.
I took the trim gauge out and used a 9V battery to test it. The lights come on, and there is some activity on the trim needle.
I also tested the pin voltage which register something around 3 volts.

I'm handy enough to figure things out, but I have not worked with boats or gauges in the past, so I'm not really sure what to look for. The gauges are similar to these http://greatlakesskipper.com/product/56_350-gauges-gauge-sets/6975--century-5-piece-outboard-boat-gauge-set.html
Memorial day is around the corner, I have all the access panels open and ready for some digging. Any troubleshooting tips, wiring diagrams, etc.. are appreciated. Please help. Thanks.

The engine is a Yamaha 150hp.
I did some more research since the posting, and found out that a black box known as MDC-1600 made by Kysor Medalion has been faulted by all gauges going down at once. Does anyone have a drawing diagram of the box?
