After I shut my 13 limited down I notice an electrical whining noise. My dyna SG never made this noise. Is this normal?

Thanks

 

You sure its electrical? My 13 RK and 08 Dyna both make a whistling noise when i shut them off. Somebody told me it was the pistons.

 

It reminds me of a car shutting down with the electric fuel pump. Only not as loud. Kind a long wining. Does not sound like a whistle.

 

Hmmm. You got me. Has it always been doing it?

 

Maybe its the pressurized fuel line in the tank. Try opening the gas cap than shut it off and see if its audible through the cap opening.

 

Tried opening the fuel cap and no dice. I did not know if touring bikes have some after shutdown process that makes a noise. It is wierd just some kind of a noise like when you flip the on switch. Like the fuel pump but not as loud.

 

Is this new or has it always done it? What voltage do you see while it is running. About all I can think of is the starter continues to run while the machine has electrical power turned on. One thing to try would be to start the engine, then pull the trigger wire off the starter, the single small wire with the push on clip. Then shut it off the engine and see if you still get the sound. Especially if that isn't it, push the wire back on to the tab after the test.

How long does it last? The only other thing I can think of is air passing the throttle plate until pressure is equalized if there is a last intake stroke during shutdown.
