We are new boat owners - 2001 Tahoe ob came with lake property. The boat has not been used for 2 seasons (it was winterized last year). Last weekend we trailered for storage - I put a good battery in to raise the trim to trailer & nothing (no guage activity - nothing). Is there a breaker or main fuse - I checked the fuses on the + battery cables (orange & red) - Looking for ideas (Remember I have never owned a boat) Thanks.
