Can anyone tell me if there is a way to test the ECM on a Polaris atv? I hate to buy one if it isn't the problem. My atv has no electrical power to anything and the battery is a new one. No lights, no power to anything. All connections seem good. We have 12 volts going into the ECM but only 5 volts at the ignition swich and the engine run/off switch. Is there a way to test the ECM before I commit to buying a replacement? Does anyone know what the voltage reading should be on the two orange wires coming out of the ECM?
