Magneto question
#1
On the 250cc Polaris machines, the stator in the magneto puts out 150 watts.
I am interested in removing my stock 55 watt headlight, and replacing it with a pair of 55 watt offroad lights for better visibility at night. This would mean I will use 110 watts just for the lights.
Will this overload the stator? Will I still have enough power for a strong spark at the spark plug?

I have a 1996 Trail Blazer that originally had the 55 watt headlight. When that burned out I replaced it with a 100 watt to get more light output. So far, the only thing I have noticed is that the battery seems to wear down fast if you aren't running the machine very hard when the light is on. I haven't noticed any problem with a lack of spark at the plug. Good luck..

I beg your pardon, Lurch77--if the manual calls the device a "magneto," this nomenclature suggests a permanent-magnet device, or "generator," as opposed to an alternator.
You may have hit upon the key to why Polarises (riders say) sometimes blow out all light bulbs when operated with a dead battery: without proper voltage regulation, a "magneto" (called "generator" sometimes) produces higher voltage with greater rotation.
Technically, "magneto" may be applied to any device that produces electricity by passing electrical connectors across a permanent magnet's field (the box with the plunger used to detonate dynamite charges is called a "magneto").
I hope someone knowledgeable about Polaris electrical systems will respond: do Polarises use alternators or generators ("magnetos") producing electrical current for vehicle operation and battery charging?

Interesting, CaptNemo! If I understand you correctly, a Polaris has one device for producing low-voltage current to charge the battery, and another (magneto) producing high-voltage current providing ignition.
Now, is the charging device an alternator (producing alternating current, then rectified) or a generator (producing direct current by rotating an armature in a permanent magnet's field)?
The magneto, from its name, involves a permanent magnet and an armature; the term usually applies to a high-voltage device (as used in producing a spark for ignition).

Dio.
Every bike or snowmobile I have taken apart has a "lighting coil" or charging coil and a seperate coil that produces current for the spark, this allows one to get out of the woods even if you loose your charging system. The system is set up with a rotating basket with maginets mounted to it and two or more seperetly wound coils mounted
stionary inside of it. (magenets rotate around the coils)

There are two coils, here's a link for a 2001 400 Scrambler 2X4 magneto from Polaris' downloadable parts manual.

The stator or lighting coil #7 on the diagram makes two ( on the scambler 400, six on most of the others) AC pulses that are sent to the rectifier and changed into DC.
