    1994 SLT 750 - unconnected red wire outside electrical box?

    This is my first post and will demonstrate how much of a newbie I am.

    I just bought a 94 750 and it runs great.

    The battery seemed a little low so I decided to pull it out and charge it.

    Before I took the battery cables loose, I noticed there was a red wire originating from the CDI box that wasn't hooked up to anything. Where should I connect this wire or should I connect it at all?

    Welcome to the Hulk

    Which model do you have, SL 750 or SLT 750 ?

    That loose red wire suggests someone has messed with the wiring and it is not in the factory configuration. Where does the other end of the wire connect to?

    Are you sure it is red, not Orange?

    If you have the SL, is the trim motor in place and working?

    Disconnect the battery negative cable before opening up the electrical box.

    Sorry - newbie mistake. It's the SLT. No power trim. There's only two "primary" looking red wires coming from the CDI and one goes to the battery. This one doesn't appear to have been spliced and has a round connector end as if it connected to a post or a bolt. I saw this wire in the photo the inside of the CDI but the photo wasn't big enough to show where the wire went. BTW, this site is great! Tons of great info and product links.

    CDI is the ignition module inside the electrical box.

    In a normal factory configuration the heavy red cable from the battery goes into the electrical box. It then connects to one threaded stud of the start solenoid (start relay). A thin red wire with a ring end also connects to that same stud, and the other end of the thin red wire goes to the 'Reset Button' (which is actually a circuit breaker).

    From the other connection on the Reset button a Red/Purple wire (Red with a Purple stripe) goes to the terminal board, where it then feeds everything else that needs battery power.

    Disconnect the battery negative cable (to prevent any chance of causing a short circuit while working in there).

    Open up your electrical box and have a look-see. There should be zero moisture or corrosion inside the box, and there is a rubber seal around the box rim.

    Look at how the Reset button is wired up.

    Many of the wire to wire connections inside the electrical box use what are known as 'bullet' connectors. These snap together and have a plastic insulation sleeve.

    So it cannot be the heavy red starter cable that is unconnected.

    After you mentioning the power trim possibility it makes me think maybe the guy I bought if from put a different electrical box on it. He said he had just put a new one in recently. It's possible that this box was for the one with power trim. Everything else works fine. I'm already looking to have the upgrade fuel pump on it after reading some of the posts here. I can't wait to know enough about it to be able to contribute here. I taped up the loose end of the wire and secured it out of the way.

    Still worth opening up the electrical box and making sure things are in good shape.

    When you get a new-to-you PWC it really is a good idea to spend some time going through it from end to end and learning what you actually have. It is the rare PWC that actually needs nothing done.

    I'll do that. I'm going to go get "the book" on it today. I'm pretty good with the mechanical stuff but not so much with electrical.
