I have been searching the net for info on these rectifiers to convert ac to dc. i was told that polaris makes one that is made into the cigarette lighter itself, and i was also told that skidoo has a revtifier/regulator kit that is available. Wondering if anyone has installed the skidoo kit on thier sled? Or if somone has some made up that they would like to sell, or if anyone knows where i can find one? thanks.

I've been trying to devise a way of doing it using Arctic Cat parts. I needed to replace the voltage regulator on my 95 ZRT 800 (no battery) The original is just the 2 wire version. I ordered the 3 wire version p/n 630-105. The yel/brwn wires hook up to factory electrical with no problem, as I just got my regulator tonite and tried it successfully.

The red/blue wire coming off it measures about 5 volts DC and about 4.4 volts AC. The regulator only has a single built in diode according to the wiring diags, so it's only half rectifying the voltage.

I should be able to install a second external diode and have DC voltage without too much difficulty. First I'm trying to figure out how it's done on battery sleds. Maybe it's just a simple extra component I need. I will be sure to update when I get it figured out.

I'm wondering if anybody know what this thing is that I circled in the diagram. It seems to be attached to the fuse block but brown's doesn't have a part number for the fuse block or this item.

Hello, B & E Industrial Electronics LTD in Saskatoon Saskatchewan sells the AC-DC rectifiers for $4.88ea. I'm sure that any industrial electronic supply store would sell these.

It appears the part I circled is only the cap to protect the fuse who knew they'd throw that into the wiring diagrams.

Turns out getting the 3 wire voltage regulator is not worth it if you want a DC voltage. It only contains a single internal diode and essentially gives a very noisy 5Vdc. How it charges a battery I'm not sure, but I guess batteries don't care.

Much easier to build or buy a pre made rectifier.

If your intent is to power a GPS, here's what I did. I installed the Polaris product. Maybe I have something wrong, but at idle there's not enough juice and the gps wants to switch to batteries. I do not have a multimeter so I cannot test volts at idle.

Someone else recommended a good set of lithium ion rechargable batteries. I did that and they work great. I just carry the charger and charge the 2 "AA's" at night. They last the entire day (at least 10 hours) out in temps starting at -10F. Just what worked for me.

The Polaris kit works great. Its for a NON-battery equipped sled. You simply leave your existing regulator in place, pick up a yellow wire and put this rectifier in. It also comes with a large capacitor and the 12v cigarette lighter socket, along with tie wraps and thorough instructions. Its just what you need on a standard pull start sled and you want a 12v cigarette-style accessory tap. The existing regulator feeds the rectifier regulated AC, the rectifier converts it to DC, the DC is then fed to the capacitor, then on to the 12v cig socket.

The Polaris part number for the kit is # 2872214. It cost me $43.

I dont know the electronics of the Polaris unit. But they do have a nice looking package.

I make AC to DC convertors for sleds. Basic unit is $35 shipped, with cig adaptor $40. Cat plug and play, $45. My units are not just voltage convertors, but filtered and and fully regulated with over voltage/thermal protection Regulator IC's. Polars may just be putting in a bridge rectifier and a cap, not sure.

Skidoo's. 05 and newer LC units are DC output from a three phase stator, fully regulated DC output. There is a hookup on the REV's just above the carbs. I have heard the same from the newer F-cats, not sure. The fusion's are probably the same way.

Putting in one diode, only rectifies one half of the sine wave. YOu need a full wave bridge, but you want a regulator post the sleds AC regulator, in case that regulator shorts through and sends 115 volts ac from the stator right to your PED.

The diode for the battery charger...Batteries like pulsed voltage, but since a battery is the best filter capacitor you can get, you dont need to fully regulate the voltage to charge a battery. Batteries actually prefer square wave pulses, top half of the sinad anyways.

Does that help?

That makes alot of sense. Thanks for the theory behind it.
