Another (slight) possibility is there wasn't a perfect connection between the battery terminal and the post of the battery.
By removing and replacing the battery, maybe you removed a little "gunk" inbetween the connection, and retightened everything up good.

Finally, the "check engine" light for 3-4 seconds "might" just be a glitch.
The best check is to pull the error codes (DTCs) and see what (if) the computer stored any errors.

SOURCE: I think I have a bad stator on my 2002Harley Dyna

too many variables !
Firstly check battery under load ! any battery place or auto electrician can so it usually free!
do this before replacing any thing else!
make sure all connections are clean & tight
if battery is ok get them to check the charge rate on bike! its a simple test or you can do it with a volt meter they are only cheap to buy!

If the bike is losing ALL power, I'm talking about dash lights, headlight, tail light, ALL lights, it's probably something tripping the main breaker. The breaker should be located either under the seat or behind the trianglular panel on the right side of the bike. I'd look for a frayed wire near the starter or around the rear cylinder due to the head in that area.

Good Luck

Take the spark plugs out of the engine and see if the engine turns over then. If it does but the engine will not turn over with the plugs in it, have the battery checked. Never assume a battery is good because it's not very old.

If the engine will not turn over with the spark plugs out, it sounds like may have serious problems. In this case, I'd consult a professional mechanic.

You can repost if you find out more information for us to work from. Good Luck

How to remove starter on 97 roadking

Hi Anonymous, here is the short version, disconnect battery, drain oil and remove primary cover, hold pinion gear and after bending tab back remove jackshaft bolt, remove all wires and cables from starter, front and rear starter bolts, slide starter out between side cover and exhaust, pay close attention to starter shaft coupling orientation as it has a c-clip that is not centered. Good luck

Starting problem

1. Test battery (Should read 12.5-13v). If not charge or get tested, may need replacement.
2. If battery is good, take a pair of jumper cables, connect Black lead between (-) Negative side and the the block of the engine (often there are metal brackets, etc they make good connection points). Then connect the Red lead, between the the (+) Positive side of battery and JUST TAP the end to battery connection on the starter solenoid to see if engine turns over. CAUTION: Engine vehicle is in Park, parking brake set, and will not move before attempting this procedure.
2a. If this does not turn over engine, remove starter and have it tested at an auto parts store.
2b. If it does turn over there are two paths to further troubleshoot. (1) check battery cables. One way to do this is to turn the ignition key on, and attempt to start the car by the method described in 2.. BUT EXTRA CAUTION: Engine vehicle is in Park, parking brake set, and will not move before attempting this procedure. (2) if the truck did not start in (1), then you will have to wire trace the starting circuit checking all fuses, connections, etc. (local auto parts stores or often local library, carry Haynes Manuals that have wiring diagrams int the back)

Best of luck resolving this problem.

Any engine light? Can you hear the fuel pump run for a couple seconds when you turn the key to ON?

My fuel pump on my 1997 efi roadking does not sound as loud as usual

Hi Gary, and the usual suspects are:
1.Ignition/Light Key Switch not in IGNITION position.
2.Engine Stop switch in the OFF position.
3.Discharged battery, loose or corroded connections check negative cable at "BOTH" ends. (solenoid chatters).
4. Bank Angle Sensor tripped and Ignition/Light Key Switch not cycled to Off and then back to on.
5. Starter control circuit, relay or solenoid faulty.
6. Electric starter shaft pinion gear not engaging or over-running clutch slipping.
7. Security alarm not disarming

My 2003 roadking just stopped running and the oil light is on. Can you tell me why it might be on? I've been riding for about half an hour and am now pulled over on the side of the road.

Did the oil light come on while the engine was still running? Do you have power to the rest of the bike? If not, have you checked the battery cables yet to be sure that they are tight? Is the "RUN" switch in the RUN position? Is it carburetted or fuel injected?

My engine light on my 01 road king comes on & off every few seconds. Running great though. What could be the problem???

That flashing light is a indicator of the security system, I added some lighting to the rear of my 04 Roadking, and ever since, the same light flashes, it is tied to the security system.
Mine has been like this for 3 years, LOL. Runs great, I know that I caused the problem by rewiring my rear wiring harness.
