I see the accessory plug on the 09-10 sleds are back to 12v AC.
Is there a DC power source anywhere on the sled?
I’d like to install an Autometer water temp and EGT and a cigarette adaptor for a GPS
Or will I have to get some converter?
All you need is a two prong plug,rectifier and fuse holder like this.
You can get the plug and fuse holder at Napa 6ish bucks ?
Radio shack or any good electronics store will have rectifiers. I have been using an NTE5817 silicon rectifier.
All you need to do is plug into the yellow = hot,black = ground plug under the aluminum cover next to the fuel pump plug on the 2010 m sleds.
This will finish rectifing the half wave regulated AC on the plug you will end up with regulated DC voltage max 16 ish volts.
