electrical issue on DA 380 2001

[picturethis]

Getting ready to launch. Still on dry land,..plugged extension cord with 30 amp connector plug into line 1 circuit on boat and all is well. Plug the same extension cord with same 30 amp plug into line 2 and the minute I turn any breaker on, it blows the gfci in the pole at the marina. Any suggestions?

Try swapping cords. Check for burnt marks on all connections and use your nose to smell for that dreaded electrical smell. Cut all power and pull the shore power connection on boat side. I had a melt down this winter and im surprised my boat didn't burn down .

Sorry just reread your post you used the same cord.

shut all the breakers off on line 2 ... plug cord in ... turn each one back on and see when it blows. Once you know what breaker, go investigate that circuit

I did that. no matter which breaker I turn on first, it blows the gfci at the pole as soon as the first one is turned on.

line 1 works fine. only problems on line 2

maybe its main breaker on input of line 2
