Got a problem that I can not figure out. It all seems to have happened after I replaced my batteries. First my Bennent trim tabs lose power. Then my spreader lights. Now my fishfinder, electronics box light, gps and one vhf has lost power. At first they all worked, then I go check every day or so, and seem to be losing power to something else every day. Last night both vhf's worked today only one would power up.

I just bought new garmin 3210 bdl package to most of the stuff will be pulled off boat, but I dont want this to happend to my new stuff. I checked fuses all seem ok, any ideas?

Thanks

Sounds like you have a corroded contact somewhere in the main buss.

If your 27 is wired like mine, it has two batteries -- one for each motor. Each of the batteries runs into a 1, 2, both, off battery selector switch located in reach of the starboard access panel. The selector switch simply allows you to select which of the batteries to run the "house" power on. The selector switch leads to two main busses which are located under the fish box in the transom (lift out the fish box to gain access). Check for corroded and tight connections on those main busses.
