Buzzing relays behind the dashboard

s1435

Hello All

Would appreciate an expert advise on my issues. I bought a 2004 SD 187. From the beginning bilge pump did not operate in Auto - only in manual. I knew there was some work done by the previous owner - and it was not a 'nice' work. I noticed that a brown/red wire with a fuse was connected to the 'negative' on the battery that looked weird. From the wiring diagram i confirmed it should go to 'positive'. Just for precaution i measured resistance between positive and that wire 
(already disconnected from negative) and it was pretty high. So... i connected that brown/red wire to positive... And something happened that i cannot revert back. On the switch panel - any switch i turn on juts gives a buzzing sound from the back of the dash board. Bilge does not work, stereo - blinks.. The engine will start however. 

I think i lost the ground somehow but cannot find - where. 

I would greatly appreciate any advise. I was thinking bad relays but two going bad same time - suspicious..

Thanks!

Hmmmm ... I'll see if Hurricane engineers have any ideas.

@s1435 ... here's the response from Terri in Hurricane Customer Support. Her email is tgipson@nauticglobalgroup.com. 

They could go bad at the same time although it is not common.  I can also send them some electrical diagrams as well to assist.  They can purchase the master power relays through any local Dealer.

Thanks, Steve am Terri. It appeared to be a bad relay - at least one of them - i replaced both and all back in order.

Thanks again!
