Raymarine a95 MFD & a70

[robjac...@gmail.com]

I had a short on my 1967 B39 Aeolus that affected the nav lights, stereo and Raymarine components. It’s now back up except the SOG/Depth/wind info isn’t showing. There are only dashes on the a70 when i cycle through the pages. I have unplugged and replugged all the cables, checked for chafe etc and still nada. 

Any ideas or diagnostic suggestions. 

Thx,

Rob 

PS: the stereo still blows the fuse but I’ve removed it for now. Have had an electrician onboard for 2 hrs and his suggestion was replacing the stereo and a70..
