Need location of high voltage, switched wire on new 2022 Lithium Yamaha PTV.

Klaatu1721 · 07-13-2022, 06:29 PM

I'm attempting to install a DC converter to take the 48v output of the lithium battery down to 12v to connect some accessories. Ideally, the converter needs to tap onto a wire that is 'hot' only when the key is in the 'on' position. Unfortunately, the wires connected directly to the key switch carry only a 5v signal & the converter needs the full voltage to activate. These carts are so new, that there's not much information out there on 'em yet. Anyone have any ideas where I might find such a connection?

Check the wiring diagram on page 56. The PTV carts already have a voltage step down included though, so I may have linked the wrong model. If yours is a ptv model, I’d use said wiring diagram to locate your 12v hot wire and just use that to power whatever you have.

A good converter will have a fifth Trigger wire that you connect to the key switch where the 48V power comes directly from the battery.
