Question about 2003 Harley Davidson FLHRCI Road King Classic
The battery has gone flat through lack of use for past few months while away. Security light still flashes and ignition with activates lights etc, but not enough charge to turn engine over. I need to remove and recharge or replace battery. How do I do it?

Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12 volts or better after charging.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor. Good luck

They do have the scanalyzer and it also has the ability of resetting your ECM back to operating condition. By default there is a tamper device in the ignition that will disable the bike. To my knowledge you must take it to a dealer to have the computer reset. The reason being is if you could DIY then there would be no reason to have the anti - theft device. Sorry for the bad news but you are right on target with whaat is wrong. Now for a work around in the meantime, perhaps you can buy a electric fuel pump and hard wire it from your battery, bypass the factory electronic one and use the new one until you can get the bike to the shop for the quick fix. It only takes them a few minutes to fix it. I would take your registration and proof of ownership because they are mandated by law to verify you are the owner. At least where I live they must do it.

check battery leads (both ends) , Then make sure battery is charged 100% (verry important) Get out your (Digital) volt meter set it to DC volts Connect leads to the Battery, it should have at least 12.6 v , Watch meter and start engine, if meter drops below 10.0 volts your battery may be weak and will have to be replaced, or your starter is'nt mechanicaly efficient and will have to be fixed or replaced. While engine is running note voltage should be 12.6-13v volts, then rev engine to 3000 RPM , meter should read 13.5- 15 vdc. If not you have a problem with your stator or regulator/rectifier.

Check your relay for the fuel pump, make sure you are getting power to fuel pump connector (outside of tank). Check for fuel flow when pump is on, ( remove tank to fuel rail line from intake side)be carefull this results in a good fuel stream that may go everywhere. Oh yeah and no smoking. Hope this heps as it sounds like the pump is not getting poweror you have a blockage somewhere.
