I have a problem that is driving me batty! On my 99 FLHR my left turn signal is working only part time.

• If I start up the bike and let it idle all the lights work as normal, including the front left marking light.
• I can turn the left turn signal on and it will blink as normal.
• If I rev up the bike a bit the turn signal will stop blinking, however the turn signal stays lite, just doesn't blink.
• If I turn the turn signal off by pressing the left turn button the solid lite turn signal goes out.
• If I let the bike goes back to idle from having some gas applied the turn signal starts working again.
• If I press both left and right turn signal buttons all four light blink like they are supposed to.

I put new bulbs into both the back and front and get the same behaviour.

• I don't think there is a short anywhere, if there was a short, the turn signal bulb wouldn't even light up?
  
• Could this be the turn signal module that is causing this?

Oh why can't things be as simple as my Panhead!
Thanks

they can be , cut the signals off with a hacksaw and use your arm signals.

sorry


weird problem- I can only wonder if your regulator is over volting and the turn signal module is responding to the high voltage.

or the reving motor is affecting a ground connection somewhere...maybe try a jumper wire from the turn signal housing to the battery -

also I'd try, motor off..ign on, turn on turn signal and shake the bike...bash the tires with a ball bat, looking for sign something is loose
