    Stupid battery mistake. What happened?

    So I wanted to go ride my Hawk '88 650 GT and went to start it. The engine barely turned over a couple of times and stopped. It was warm out and so I knew that the battery had discharged a bunch and needed recharging. This did not surprise me since my solar charger has been giving me some fits recently. Diagnosis: discharged battery.

    I could have taken the battery completely out and used an external charger, but I wanted to ride that day, so I decided to jump start it. Not an unreasonable choice. Done all the time.

    I had a fully charged 12V battery in my shop for such things, and I recently used it on my BMW F-800 (also discharged due to the same solar charger issue). So I attached the cables and...BANG, sparks everywhere! WTF just happened?

    Well, t turns out that the BMW mounts their battery backwards compared to the Honda. Since I had used the jump start battery recently on the BMW I inadvertently hooked it up the same way; the poles were reversed.

    I took the battery out and trickle charged it. It appears to be fine. However, upon reinstallation on the bike the bike is dead.No dash lights, nothing.

    I looked t the schematic and I don't see what would happen if a reverse polarity event occurred. Yes, current would be pushed into the frame but there are lot of pathways back to the positive terminal. Many have large diodes and/or full mechanical switches...which are had to break if the switch is open.

    Where do I start? Any thoughts?

    Main fuse at the starter solenoid under the cowl at the left side near the battery.

      Ok, I can see how the main starter fuse might have fried. However, in looking in my owner's manual and look at the bike as we speak, it looks like this fuse is deep within the bike. It is behind a part of the frame where several bars come into conjunction, and would be very difficult to get around.

      The other way we could be to come in from the top, but this would require removing the battery (no big deal) and the battery holder,,,which is a bigger deal because it is one piece with the fender. This means that I'd have to take the rear wheel off to get the fender off, to get the battery box off so I can see the starter solenoid from the top.

      Am I missing something?

        ^^ you are.

        the main 30amp fuse is part of the starter solenoid under the seat section plastic, right side, very ez to access. the diode will need replacement too, right side up near the airbox.

          Take the rear cowl off. Taking the battery out does nothing.

            I ma looking in the user's manual and I do not see a fuse near the starter solenoid. The text doesn't' mention it either. It has an exploded view of the starter, yet no fuse. Could the fuse have been remotely located?

              Stop looking at the manual and look at the bike.
              LEFT side, under the seat cowl. Follow the big wire from the battery positive terminal. The fuse is under a rubber cover on the top of the starter relay... shown in the manual

                The fuse is under the connector on the starter solenoid. Like Parc said, remove the tail and it will be staring at you.

                    It isn't hard to get at.
