I have read other threads but couldn't seem to find the exact details on the information I need. I was running at about 75 mph for about 10 minutes and randomly the bike starting cutting out and bucking a bit as I tried to keep it gassed. I pulled off at an exit, made it to a stop light and I had to keep the throttle open to stop it from stalling. I had to use a ton of clutch to get it moving and it continued to run extremely poor until I got home. I have heard this could be a short, bad battery, bad voltage regulator, bad spark plugs....etc. So far I have checked the wiring and all appears fine with no worn away insulation. The battery was replaced last year but it was not a Harley factory battery, it was one of the cheaper kinds. The voltage with with everything turned off is around 13.5V. When I start the bike it quickly drops to 10.75 and then settles around 12.75 while idiling at 1k rpm. When I run the bike up to around 3k rpm the voltage climbs up to a little over 14 V. Does this sound like the voltage regulator going bad? I looked through the manual and couldn't find out what the battery should be with no load and under a 3k rpm load to see if this is irregular. I know this is similar to other listed problems but it seemed other people had the voltage going up to around 17V, which I don't have. Any help is appreciated.

It sound like your stator is failing or coming unplugged. You should have 14 volts at idle. Got a multi-meter with AC volts? Unplug the stator from the voltage regulator and check your voltage at idle, and at 2000 rpm. You need 28 VAC to fold into 14VDC at idle; the AC voltage should rise to 38 - 54 as you raise rpm to 3000. While it's disconnected, check for shorts to ground from either wire and resistance between the two (should be very low, around .2 to .5 ohms). If there is a short to groound from one wire only, your wiring is more likely at fault than the stator itself. Pull the wire all the way out as if you were about to replace the stator and feel it with your fingers for a lump or a break in the insulation. Mine had a badly repaired wire break from the factory which rubbed a bare spot in the insulation at about 25,000 miles. |

Sounds to me you need to do a TPS (Throttle Position Sensor) reset.
If you don't have a manual, you can take it to a shop and have them do it. |
