Question about 2005 Harley Davidson XL 883C Sportster Custom
Battery went dead now bike won't start
Posted by Anonymous on
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

SOURCE: Bike wont start
First thing > install a new set of the stock NGK spark plugs for your bike. Check for spark before installing. If no spark, then check to be sure the battery wires are clean and tight. Is the kill switch on? Is the side stand up? It should be up when starting. Is the bike in neutral? Check the fuses. Check the wiring connections, are they tight?
If spark is present, is the gas turned on? Clean or replace the air filter. If the bike still will not start go ahead and drain the carbs. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carbs to fill with gas. If the bike doesn't start properly then shut off the gas and remove the carburetors from the engine.
For both carbs > remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together. Remount the carbs.
Next, remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Turn the gas back on to let the float bowls fill then start the engine. Be sure to balance and sync the carbs when finished. If you don't know how to balance and sync the carbs, get back to me after you do the stuff mentioned above. This process should get you back on the road.
Please rate this solution as " FixYa " if all goes well. Thanks!

Sound very much like a low charge rate(your bike is not recharging the battery).
You need to have the bikes charge rate checked.
Basically-your bike should charge at a rate of 13.4- 14.2volts(DC) when running.
If it's not- the battery will keep going flat.
The test is performed by starting the bike & placing a voltmeter across the battery to measure the output.
It's a relativily quick & easy test to perform that only takes a few seconds-but if the charge rate is low then its caused usually by the regulator or the alternator(stator).
If you have a multimeter-or know someone who does-then the test is pritty easy & you need to do that before you go any further.
If you do it yourself- set the meter to Volts DC at a range higher than 15volts(if the meter is not auto-ranging) run the bike with the volt meter probes touching the Battery(black probe to battery negative-red test probe to battery posative) & observe the voltage reading.
You want 13.5 to 14.2v.
If you can't do it yourself then an auto-electrician or bike shop should be able to do it while you wait for just a few dollars.(only the test though- if the charge rate is low then you have then other issues to solve)
I hope this was of some help
Kind regards Andrew Porrelli
