DC Power Plug for Hand Warmers?

[Pownar]

In the manual it says:

DC PWR Plug
Connect the Chassis Power-Up Harness to the DC PWR plug to supply battery power to the following components:
• Instrument cluster
• DC accessory power points • LED tail lamp/brake lamp
ECM PWR Plug
Connect the Chassis Power-Up Harness to the ECM PWR plug to supply battery voltage to the following components:
• Digital WrenchTM communication connector • ECU
• Chassis relay driver coil
• VES solenoid
• DC Power capacitor
• Fuel pump power side


Is it the little non labeled one on the right(I guess it would be on the top after my pic. was tuned counter clockwise).

Do I really need a harness or can I just hook up a 12V to the ECM PWR Plug to test the Hand Warmers?

It looks like 12 DC does not go to the hand warmers. The stator puts out AC. The regulator takes that AC and converts it to DC for the ECM, gauge,sensors, fuel pump. The head lights and warmers use regulated AC. Light blue and light blue/red wire in the connector on the bar heater are power and brown is ground. Heaters have 2 windings in them. A fine one and a course one. One for low, one for med and both for high. I am not sure if running 12 v DC will hurt them or not for testing. I doubt it. If you are chasing a warmer that doesn't work, I would unplug the heater in the handle bars and test each side individually. This will isolate them from the sled. Next I would probe the mating connector with the sled running and see what the ouput is on all 3 switch settings. Attach meter to Brown and then probe the light blue and blue/red while flipping the switch. You should see 12-14 v AC comming out of those lines.
Ground the mating brown wire on the heater and apply 12 v DC to the other 2 lines momentarily and see if they get warm. Repeat on other warmer. Those warmers are looped together so test at the connector close to the heater.
Common problem on heaters is the throttle block gets twisted on the bars and breaks or shorts the wires on the right heater. I wish Polaris would not run that wire under the throttle block then that wouldn't happen.

Thanks 454. My Dragon is so easy to power up with 12v dc. It powers almost everything right from that little plug by the steering column. I did end up hooking 12v directly to the hand warmer connector just below the bar riser and it told me what i needed to know and once fixed i was able to test the heat output. You were dead on. It was the right heater brown wire was separated just enough that it wouldn't work but couldn't tell it was separated. The weird part is it's my wife's sled and she doesn't put a lot of torque on anything so I don't thing she ever twisted the block. You would think that Polaris could make a heater that lasts more than 13 miles!
