JetSonic JS1

[Stampeed Valkyrie]

First Video of 2022 (officially) I have some pictures of the bar as I was going over it someplace, I'll upload them when I can.
Smart bar, all functions seem to work other then front cutoff. I'm still learning as I go with these bars, its only real option installed besides alleys is the front passenger side takedown.

i suspect the bar may be backwards why the amber facing front

That was me, I just happened to have an amber sitting around and did not want to go rooting for a clear or another red.

I love these bars. I prefer when they have an alternating flash, but I know so little about the technology that i don't know if that's a feature of this model or not. Overall I love the "smart" chain drive jets.

I checked the Service Parts Index, the drive motor should be on the driver's side of the bar, so it appears this particular JS1 is facing the correct direction.

The service parts index is something I would really like to see scanned and archived.

Don't think I'm going to scan my SPI. It's 382 pages and the binding would be destroyed.

Beautiful bar there. I just got a model J bar, with no mirror seperation, but alt flashers for the rotators when parked, front cutoff.

Now for your cutoff not working, I am no wizard when it comes to the electronic board inside, but if you hear the relay clicking for the cutoff, it obviously does work. I'd check the relay output with a multimeter to make sure there is voltage coming out of it. Might be just a bad connection between the relay ouput and the actual flasher cutoff.

Be careful with the prongs of the meter so no contact shorting happens
