Another post got me to thinking about putting this together. It's gonna be a long read, but lectricity can't be splained in a few words...LOL
There seems to be lots of questions about how much power is available on a sled....primarily M sleds.
Most sleds have a decent amount of power typically 200 watts or more. This means, that there is over 15 amps of current available at 10-13 volts. Warmers and lights can use up 1/2 of that so there can still be 7-10amps left over for other goodies.
Most of the time we need DC power to run pumps and guages and controllers....etc. DC power is like what is available from an automotive system. This isn't always available on a snowmobile, but there are ways to get it. Stators, magnetos, alternators all make AC power. This power needs to be made into DC to use most automotive components.(Auto alternators change AC to DC internally).
05, 06 (M6 and M7) have a lot of AC power for hand warmers and lights. This power comes from one winding in the stator. It is regulated down (10-12 volts) for use in the light/heat circuits. A tiny bit is rectified(turned to DC) for use by the APV servo motor. Another winding in the stator supplys power for the fuel pump. It is turned to DC There is only enough amperage from this winding for the stock(small) fuel pump.
The typical way to get DC power to run big fuel pumps and other devices is to wire a bridge rectifier into the lighting circuit. From this rectifier, DC powered devices can be run at almost the full output of the lighting coil(minus the heaters and lights). There is an issue with a stock ground wire so you can't ground anything that is in the DC circuit without having a gremlin or two show up. Too much to explain here.
07, 08 (M8 and M1000) have DC circuits from the CCU to power the mechanical reverse. That means all your work is done. Just hook up any aux equipment to the output of the CCU and your off to the races.
09 (M8 and M1000) went back to the old AC system. So now there are a few choices. The old bridge rectifier option is available just like the M7. The second, a savy tuner could use an earlier model CCU instead of the Reg/Rect assembly and run all the DC power from it.
Please keep in mind, this is the condensed version. If you are going to modify your sled's wiring, enlist some help from someone who is used to chasing electrons around a circuit. Always use a meter to confirm voltage and continuity of curcuits, and be wary of your grounding.
There are lots of folks on here who have the electrical thing figured out so please add to this as questions arise.
Hope this helps bring a very basic understanding of electrons and snow...LOL
