electrical issue with 2002 bay liner 185 capri

[rabebh]

Everything ran great last summer, then I sent someone else in to put the battery in and they crossed the wires putting them on the wrong post. Now when I turn the key nothing happens. Anyone have any ideas where this issue could be?Thanks in advance

Start with fuses. Big one near the battery, positive side.

It was the 90 AMP fuse thanks for the help. QUOTE=foodfisher;n7905006]Start with fuses. Big one near the battery, positive side.[/QUOTE]

[A problem was found in the] the 90 AMP fuse[.]

You can consider yourself extremely fortunate if the connection to the battery with the polarity reversed has produced only this simple problem of a blown fuse.

Clearly identifying the cables that connect to the battery with RED and BLACK markings and clearly marking the terminals of the battery with RED and BLACK will help to avoid repetition of this mistake.

I would not characterize this as an "issue." There is no dispute that connecting the battery with the polarity backwards is a huge blunder, and it exposes the circuitry to all sorts of possible damage.
