Harley davidson street glide wont start warm

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!

Check your spark plugs, they are quite fragile & yoy may have a crack in the ceramics. Replacement is recommended.

Idle speed on a fuel injected bike must me set by the dealer if it's still stock. I think you can set it yourself in you have a Power Commander on the bike but I don't know how to work with that unit.

Does the start quit turning or does it continue to sound like it's turning? If the starter quits turning, I'd suspect the battery. Take it out and have it tested. Usually no charge for this service at most any auto parts house.

If the starter sounds like it's still turning but the engine isn't, that's an indication that the "starter clutch" is bad inside the starter. This is the "one way bearing" unit that turns the engine to start it but then freewheels when the engine starts. I've seen many of them go bad. If the bike is still under warranty, take it back to the dealer before the warranty runs out. At least have a documented complaint of the problem within the warranty period. That way, if the warranty runs out you may can still get it fixed under the warranty.

Testimonial: "Very informative and explained the possible issues in plain English very well. I will check your suggestions follow your advice. Thank You very much."

I'm not too familiar with the later model bikes but if I were getting a clicking noise under the seat and the bike was not starting, I'd investigate the source of the noise. It's possible that it is a starter relay that engages the solenoid that is an integral part of the starter. Look at the starter from the right hand side of your bike. You'll see a single small wire that connects to the end of the starter just above the end plate of the solenoid. Disconnect this wire and connect a test light or volt meter to the wire. Turn on your ignition switch and press the start button. You should hear the click under the seat and see voltage at the end of that wire. If not, replace the relay, a plastic cube about an inch in dimension.

Good Luck
