led turn signal resistors

[suzyj]

My LED turn signals do some weirdness.

With the motor running, they flash a the correct rate.....

.... but if I flip the turn signal switch with just the ignition on they flash at blown bulb speed  

And even weirder.... they didnt used to do that when I first installed 'em (nope cant remember how many ohms my resistors are).

I'm not stressing about it coz they flash at the correct rate when I really need 'em... but I do wonder if some electronic damage is afoot.

The chip doesn't just sense blown bulbs. It also senses over current, over temperature, and low battery volts.

At a guess, you've got a dodgy connection between your battery and gauges, with significant voltage drop under load. Enough to trip the low vbb sensor on the driver chip when the bike isn't running...

Just a guess.

I have low battery volts.  Still the original stock (3 year old item), spasmodically tendered, parked idle more than it runs lately.

Explains why I now get hypo-flash until the motor is making juice  .
