I have a 2007 Harley street glide battery died. I replaced it then the radio would not work. checked the fuses and found all ok. I road it for one day and let it sit for 2 days and the new battery is dead. I charged the new battery on a trickle charge for 24 hrs before installing it. Any one know the reason for the battery going dead?

1.What?

2.What?
You charged the battery off of the battery charger with a trickle charge. The battery wouldn't charge while you're riding, because your alternator took a cr@p.
(Sorry if I seem gruff, but I'm an old biker, and Harleys are all I ride. I'm also a Harley mechanic.
Shhhh! I don't want that to get around! lol!)

3.Battery is at 13.4 volts now? What is the specific gravity of the acid in each cell? Don't have a hydrometer? Do you have a load tester? No? Since you measured the voltage, do you have a multimeter?

Test the voltage with the bike running. It should be around 14.6 volts when charging, less with the battery fully charged.
Don't get the correct reading, then you better look at alternator replacement. (Regulator is built in)

my roadking just did the same thing, check the gasket between carb and intake

Your bike has a stator and a voltage regulator. On the right front down tube you will find the plug for the stator and the voltage regulator, unplug the stator from the voltage regulator and use a meter to read the out put from the stator. I don't know the value's off hand but as you rev the motor the voltage should climb. If it doesn't your stator is bad, major job. If it does measure the voltage on the battery cables, when you rev the motor they should climb to a little over 14V's.
