Need to find an easily accessed ACC wire....

Try the accessory plug in the glove box
That one is easy to get to.

Sorry, as I wrote above, "The one it is connected to now seems to be having trouble. It is the wire that goes to the 12-volt glove box plug."

Need another..............

Sorry I missed that -

That was the only one I could think of

I am wondering if that wire is causing trouble because the dealer tapped into the wrong one? There are two wires coming out of the 12-volt plug. Which one should be tapped into?

Not sure of the colors because I can't get to mine without removing a some stuff but the wire going to the casing is usually the ground and the one going to the post in center is usually the positive.
If you have a test light it is a quick check

sorry pressed for time but I think this video Polaris Slingshot FZ-1 Fuse Block with Wiring Harness tells you which wire

4:30 gray / red wire

Thanks but as mentioned I cannot use the wire they recommend to tap into which is the 12 volt glove box plug............

sorry thought there was a question about if they tapped the correct wire

I didn’t have any issues using it for my neutrino.

That's nice. Mine seems to have a problem.

O/T I know, but Studiopeg, did you call your slingshot dealer to verify the warranty status for your slingshot? (1 year or 2)

Couldn’t you tap into where they’re pulling from the remote turn on of the amps?

Turn signals only have power when activated. The rear tail lights (NOT the bake lights) should always have power if the key is turned.

The glovebox switched power outlet has a grey negative wire connected to the outer connection when looking at the power outlet from the engine area and a white w/red stripe positive wire connected to the power outlet's center connection. The Neutrino's yellow wire should be connected to the white w/red wire. If the Neutrino yellow wire is connected to the grey wire, it may or may not operate properly since that wire should only carry electricity if something is connected to the power outlet. It should be reasonably easy to tap into the white w/red wire from the engine compartment side.

This might sound silly, but are you sure you’re not hooked up to the cigarette ground wire instead of hot?

One more thing, are you sure the neutrino is not defective?

More than one way to say ditto...
