Re: how to get to the negative terminal on the battery...
Nothing needs to be removed. You have to move the swiring around just a little. Magnetize a 11 mmm socket and set it on using a 1/4 inch ratchet, with a short extension. Loosen the nut and pull it out. Its a bi&^%$%^ to get out but it will come right out and then pull the battery out the side. make note on how the cables are set on the battery so you put it back in the proper way and the battery cables dont touch anything when you put them back in the holder. Hope this helps. TOM

Undo the screw on the batteries neg. terminal and remove the connector from there. Then remove the nut or bolt on the frame or engine case where the other end of the cable is attached. Get or make a new cable and then reinstall in reverse order.
Is it a Harley part? If so, the red wire or wire with red connector on it goes to the positive terminal of the battery. The other wire goes to the negative battery terminal. If it is an aftermarket part, or just has 2 wires, the wire that is attatched to the body (the outside) goes to ground or the negative battery terminal. The other wire goes to power or positive battery terminal.
You can charge the battery without removing the battery. Find the large cable that comes from the battery where it connects to the starter. Connect you positive charger clamp there. Connect the negative charger clamp to any good frame ground on the bike. You can charge you battery using this method provided you battery charger clamps are not too big.
If you can't do this, you'll have to take the seat off the bike, remove the battery hold down strap, and then move the battery outwards so you can disconnect the negative battery cable.
Yeah ,it's a ***** , remove the neg cable from the batt,neg and also from the other end ,. thats your ground, either fabricate a cable 2 inches longer , stay with the same gauge wire and crimp ends , if not take the cable to and electrical shop and have1 made While you at it Add 2 inchs to the pos cable , then its a breeze. These cables have and enherent Proplem of comming loose ,. use Blue locker . Loctite and use 1 drop on the bolt threads,. beware ,. don't over do it ! Than coat the Batt terms with red grease , stops the corrosive effects ,. Please take my advice,. I know ,. I lived with this lil nitemare ! Bruce
One of them should be red, with a plastic cover on it, and the other one black, and they should only reach the terminal they belong to, The battery should only fit one way, for the wires to reach it. So, red is hot, or +,, and black is neg, or -,,, Hope this helps.
According to the website here, you have a Sportster. To get the battery, first take the seat off. There's only one bolt at the very back of the seat that you need to take out to get the seat off. Remove the bolt, lift up on the rear of the seat and pull to the rear. seat is off.
Now, down by the battery, there is a strap that runs across the top of the battery cover. It is tightened by a nut on the right side of the battery. Loosen the nut until you can take the strap off. Remove the top and side cover off the battery. Disconnect the negative side of the battery first. You need either a long screwdriver or an extension with a 10 mm socket on it. Take the bolt out of the negative connector from the right hand side of the bike. Then use a 10mm wrench to remove the bolt from the positive side. Lift the battery out of the tray.
Now, you can recharge the battery yourself but I'd advise taking it to an automotive parts house and have it checked. They'll charge it and load test the battery. When you reinstall the battery in your bike, connect the positive terminal first and the negative terminal last. The rest you put together in reverse order. Good Luck!
Ok, the battery sits in the frame of a sportster with the terminals towards the inside making removal difficult. With the seat and the battery cover removed, you can see the negative connection of the battery towards the front of the bike. Usually, you can get to the screw at the negative battery terminal from the right side of the bike with a long Phillips screwdriver or 10 mm socket. This is how I get them out. Always disconnect the negative first when taking the battery out. Always reconnect the negative last when putting the battery back in. This will prevent you from arcing the battery and possibly burning a hole in your oil tank. I've seen it happen on many Sportsters. Good Luck!
