I'm going to stop adding to the discussion and simply summarize with this.
These are my opinions that I feel strongly about.
There are 2 completely separate and independent Stator circuits. One supplies the ECU and Injector systems... the other the lighting/heating/charging systems. Both systems have separate/independent coils in the stator, separate Voltage Regulators (VR's) and are not connected to each other. Even though the 2013-2015 models have a common case for the two separate VR's to save weight... the VR's inside that case are separate for the two Circuits.
These sleds.. with their simple "bare bones" charging systems and dedicated "BatteryLess" EFi systems are specifically setup and purpose built. They were not designed to have a clean 12V accessory power supply for anything of significant draw above 2amps. Are there ways around it... yes... some good and some not so good... the "good" ones will take a systems-approach that considers all component and quality/durability/reliability of output that does not compromise essential systems onboard.
I have personally helped people fix poor running sleds, both turbo and non-turbo, simply by deleting auxiliary loads or moving them to a more appropriate source.
I've also personally repaired a 2013 Turbo PRO RMK that had defective oil pump that ruined his ECU and VR... that pump was plugged into the "DC Pwr" plug with no fuse. That sled left him stranded in the backcountry and had to do a difficult tow out that took the whole next day. The cost for the parts, ECU, VR was over $600 plus the cost of the pump and my labor. He now has over 3500 flawless miles on the sled running all accessories (pump, AFR, GPS) off of the AC Pwr circuit.
The "DC PWR" by the Clutch and the "DC ACC" rubber plug by the headlight come from the same source... that source powers the ECU voltage regulator. The "DC-ACC" connector is fused... the "DC Pwr" connector, by the clutch cover, is NOT fused. This source is completely independent from the lighting/heating/charging coils/VR.
The DC-PWR/DC-Acc circuit runs off the Coil/VR/Capacitor installed at the Polaris factory in your sled... the ECU system on your 2011-2015 PRO RMK.
That circuit was never intended to power many accessories... A visor or GPS/Cell charger sure... fans pumps and auxiliary lighting... no.
The factory put a 2 amp fuse on there as a MAX extra draw for a reason... It supplies only the rubber-connector DC ACC. The Polaris and Kokusan-Denki engineers had NO intention of anyone using the DC plug by the clutch to draw power from... that connector is an INPUT for system-testing and hence has no fuse on it to protect it or the ECU.
After talking to the factory engineers, and looking into the electrical system on PRO, extensively (more than most could value) ... I do not recommend powering anything off the ECU-VR supplied DC other than through the FUSED Rubber Plug and do not use anything more than a 2 amp fuse as a fuse. If you blow a 2 amp fuse, it means that you are drawing more current than the system was designed to handle.
Do not put any motor loads onto this, like a fan, as you will induce electrical "noise" into the ECU system.
There will be members that will chime in with reports to the contrary... and I can say that I sincerely hope that you never have an issue.
Use what you want to use... in the end, It's your sled.
