Hey all, my 2005 Sportster 1200R wont start, I tend the battery after every ride with the $20 walmart charger. Bout a week ago, battery seemed to be getting weaker, now is completely dead. Battery is only about 6 months old (NAPA) and should still be good. Tried to jump it and bike STILL wont start (just get a click click click and a weak attempt to turn over). Thinking it could be stator? or voltage regulator? or what? Any suggestions would be greatly appreciated.

 

get the f**king manual. I bet its #5 rookie.

Engine Will Not Crank
Check for one or more of the following possible malfunc- tions:
1. Ignition switch turned off.
2. A faulty ignition switch.
3. Engine run switch in off position.
4. A defective engine run switch.
5. Loose or corroded starter and battery cables.
6. A discharged or defective battery.
7. A defective starter.
8. A defective starter solenoid.
9. A defective starter shaft pinion gear.
10. Slipping overrunning clutch assembly.
11. A seized piston(s).
12. Seized crankshaft bearings.
13. A broken connecting rod

 

If you read and understood the OP's post, you'd know 10 of the items on your above list have about a Zero probability of having anything to do with the OP's problem.

 

Check Both ends of Both battery cables and make sure they are clean and tight. If that doesn't do it, take the battery to an auto parts store and have it load tested.

A fully charged battery will measure 12.8 volts.
With the motor running at a FAST idle, you should measure between 13.5 - 14.8 volts across the battery. If it's less than 13.5 volts, you likely have a bad stator, regulator, or both.

 

The statement "I tend the battery after every ride with the $20 walmart charger." is a bit confusing. Are you using a tender or a charger? If it's a charger, you may have killed the battery with it. If it's a tender, go with what cHarley said.

 

This is what first popped in my head too.
