Motorcycle Repair: Harley Electrical, battery connections, battery problem

Question
Dear Mike,
Wow. what a great and fast service. You guys are great.  Well I checked the grounds, everything seems to be fine.  I reinstalled the new battery and same thing. Not enough juice to light the lights up very much and not enough to turn the starter.  I removed the battery and hooked up my charger/starter to the lead wires and she fired right up.  Could it be a bad battery even though it is brand new?  Could it be that the jumper battery has more power, thus able to turn int over?  Any suggestions?

Thanks.-------------------------

I own a 2003 Road King with very low milage. (1500 Miles)  I went to start it this year and the battery seemed dead. Since it had been sitting over the winter I put a new battery in. The new battery was completely charged but doesn't seem to have enough power to start the bike.  Just to make sure it was charged I put a charger onto the battery and the lights came up brighter and the bike started fine with the charger in "Start" mode.  

When I disconnected the charger, the bike died.  The bike will only run with the charger attached and dies the second I remove the charger.  What do you think is the culprit?

Thanks,
Tom
Answer -
Check your battery connections at the battery as well as at the negative end to the ground. Sounds like you have a bad ground.
Good luck and happy riding

Answer
You can have a bad battery even though it is brand new. I would have it tested  and see if its bad. You say you tried a charger/starter to the system. I dont know how many amps it is, but it might be more than the battery puts out, but go with the battery problem first.
Good luck and happy riding
