Hi Mitch_steven, 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: Voltage problem when running bike

The voltage regulator should present 13.5 to 14.5 volts at the battery to charge it properly (engine at fast idle). I'm not sure if the V regulator is adjustable or not. If not, then it probably needs to be replaced. The alternator appears to be trying to do it's job, although it may have an open diode or winding if the alternator is 3-phase. An oscilloscope is the best tool to check for all three phases working properly. Good luck!

SOURCE: while riding the voltage regulator ranges from 16

If power out of the regulator is down to 10 volts then the regulator is naff - replace it!
If power going into regulator goes as low as 10 across the phases then the alternator needs rewiring (not very likely)

Hope this helps (if so please mark as very helpful)

SOURCE: I've checked with an Ohm meter and have continuity

If you are checking from one of the stator prongs to engine ground and you get continuity, your stator is bad. It would probably be a good idea to replace the regulator. I think Harley sells a kit that is priced fairly reasonable. But, check the rotor. I've seen one rotor that didn't have any magnetism in it. That's right, It was a genuine Harley part and the rotor had no magnetism in it. It was a friend of mine that put the stator in another guy's bike but it wouldn't charge. I checked everything and found nothing wrong except no output. Pulled it down and that's what we found. We simply put the guy's old rotor on it and it worked fine.

Good Luck
Steve

CHECK ENGINE LIGHT COMES ON AT START UP AND IDLE. NO ROUGH IDLE NO SYMPTOMS?????


Have you pulled the error codes?

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.
4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.
7 - Record the codes.
8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.
9 - Press and release the odometer reset button to continue to the next module.
10 - Turn Ignition switch to OFF.

What do the codes mean?

Why does 2003 windstar shut down electrically


Before replacing alternator testing should be done , is there B+ voltage at the heavier gage wire on the back of the alternator . Could have a blown fuse or fusible link . Your vehicle from what you have posted , isn't charging . Plus there is a regular fuse located in the under hood fuse box F1.13 - 10 amp this supply's B+ voltage to the orange with lit blue stripe wire at the three wire connector plugged into the alternator . The other two wires come from the PCM - engine computer . This charging system is computer controlled . Ford PCM controlled alternator testing

The head lights on my 2004 Roadking Classic dim and them brighten up while in am riding


The relay contacts get carbon (or burn away) on them from arching and cause a high resistance contact ,thus the dim and not working tach ,lights. Check your grounds, and connections for shorts.

Kawasaki kmx125 lights go dim when revving engine. work fine on i


I had the same issue, and it after lots of testing and measuring, found out it was only that 'earth' wire that you have at the bottom left part of the engine, coming out from the left engine cover. You will find it easily, it's a standalone wire, mine had its sleeve too dry, might have been why it was not well connected. It also had a mix of sand and oil in it, so no wonder the lights would dim out. The wire plugs into some sort of a screw, you really can't miss it :) Even the old, worn sounding Yuasa battery got back to perfect function, only added distilled water to it and let it run fro some time. Cheers:)

New battery goes flat in single day


check for short circuits. it can be stripped wire that makes contact with the bike chassis. This can drain the battery. Also, Charging circuit may be dead (alternator and regulator).
