Bad battery last winter I fixed a short I had going to my rear liscence plate lite. I also put a brand new battery in this april when I started riding again. Well today the battery died AGAIN. Brand new battery just dies. Last couple weeks I hav e noticed that it was starting hard. I drive 12 miles one way back and forth to work. I was able to get a jump from a friend. I rode to the gas station 11 miles away. Turned the bike off pulled out the key. Filled the bike up put key in and the bike started right up. So that tells me my charging system is working. SO does this mean I have a bad battery after only 2 months of riding? Or is my only riding 12 miles 1 way not enough to keep the battery charged???

Battery could be shorting out itself between cells. When it heats up it shorts out when it cool down it doesnt. This is one reason i like interstate batteries. They are made of all new material. Most brands are rebuilt batteries.

cheak to make sure they are wired correctt it sounds like you might of crossed some wires does the indicatoer stay lite when the turn switch is off that would licnence plate light hooked into signal

starter cannot act good if it does not spin the engine over quickly with new battery
pull it for a bench test under load
check and clean terminals and check for good ground point

Stale fuel is normally the cause for bad starting after the winter, fuel has a very short shelf life before it goes stale, drain the fuel tank and carb float bowl, refill with freash fuel and try again

You said the battery is fully charged but is it any good. A battery with a shorted cell will show a full charge but will short out when you put a load on it dropping the voltage below 12 volts. I would suggest that you remove your battery and take it to an automotive parts house. They will usually load test your battery for no charge. If your battery is over two years old, you probably need a new one. Motorcycle batteries usually don't last much longer than two years due to the vibration they are subjected to. Make SURE you battery is good.

If this doesn't work, look at the end of the starter on the right hand side of your bike. There is a pentagon shaped plate on the end of the starter, actually it's the starter solenoid. Remove the three screws from the plate and remove the plate. There is a spring under the plate but it's not really strong. Inside the solenoid, you'll see a plunger with a round copper contact ring on it. You can pull this out. Now, look at the large copper contacts on either side of the solenoid. If they are badly burned, you may need to replace them. You can obtain a "rebuild kit" from most any "independent aftermarket shop". Your local Harley shop may order the parts for you as well. The kit consist of both the side contacts and the plunger. If this does not fix your starter, the starter motor itself may be bad.

This sounds like the Technical Service Bulletin for the wiring harness but yes there are 2 TSB for the charging system most recent April 2007

Is the car trying to do anything? If it just clicks, check the connections to the battery and make sure they are clean and tight. (no corrosion) Also, hopefully you charged it with the negative cable off (not a huge thing) but do not try to bypass the battery and jump it and try to get it going on the alternator- this can damage the electronics in the vehicle. The battery acts as a buffer to prevent damage to the vehicle's electronics. Lastly, you may just have a bad cell in the battery. They can corrode over time and on rare occasions they can literally short out themselves, Hope this helps you.

Adjust your idle a little higher for the winter.  The adjustment will be near where the accelerator cable is attached to the intake manifold.

I bought my B&D cordless mower CMM1000 (very similar to the CMM1200) in April 2003. I made the mistake of following their instructions and stored it inside unplugged the first winter. Never again! The battery would not hold a charge April 2004, but was covered under warranty. Since then, I've left it trickle charging in the shed year round, including cold winters. No problem since then with the battery, which will last about 5 yrs before you need to replace it.

though if it was a problem it would have blown the 10amp fuse????Don't rely on on whether the bike will start at a gas station to determine if the charging system is working. Get the multimeter out and do a proper test. Should be getting about 14.5 volts @ around 3K RPM. It's too easy of a test to to just skip. If it is charging then start looking for something else. Was the new battery properly charged to begin with? Loose battery connection? I suppose the GPS could be too much but you said that it was dying last november so I would suspect something else. P.S. you need a properly charged battery to get an accurate reading for the charging test. ,,,
