QT , the 2006 700 has a device under the hood called a POWER DISTRIBUTION MODULE . It is a silver box with fins on the passenger side. Polaris installed this 'solid state' garbage instead of installing relays and fuses and a voltage regulator . Almost everything that requires power is routed though this PDM . It is also known as a ECM that is NOT TO BE CONFUSED with the ECU that is mounted under the drivers side seat. When a PDM starts to go , normally it is the fan that is effected . It will usually NOT come on at all but sometimes it will come on with the key when the engine is COLD . Many times when you pull the big plug connectors out of each end of the ECM, you will find that (3) fat yellow wires which come from the STATOR have the pins a bit toasty where they enter the connector. these wires are routed into the PDM because the VOLTAGE REGULATION is done inside.
You need to verify that the fan is good by unplugging it and if it does not automatically turn ON , I would wire 12 volts to it to verify that it operable. If it comes on with the aux 12 volts that you put to it , I would say your ECM is on it's way out. It normally starts with the fan then works it's way to the fuel injectors etc and then in the end you turn the key and then nothing happens including no starter .. The worst thing on a ECM I have found is a weak/bad battery. This will start the death process of the ECM.
You need to check the condition of the STATOR per the SERVICE MANUAL.. Easy enough to do with the instructions in the manual. >>>>
