I am lost too. There is no reason for the voltage to go away from the yellow wire when you remove ground. Do you also have a switched 12 volt source for the red wire of the radio? If so does it act the same way?

Isn't a Polaris Ranger an all-terrain vehicle? Does it even have an alternator? Is it a voltage regulated system?

It is an ATV with electric start. We have put systems on a couple of them. We have replaced the roof with a Rhino-Lined MDF enclosure for 4 speakers, radio and an amp.

Something I have recently encountered:

Not saying it applies here, just didn't want to start a new thread.

Marine systems are starting to use Yellow as ground return. Both RED / Black and RED / Yellow acceptable for DC systems. It wouldn't be a surprise if this expands to other products.
