|UTV Voltmeter Installation
After adding quite a few 12 volt accessories (4 HID lights & heated seats) to my Polaris RZR, I wanted to keep track of how well the charging system and battery condition were performing. The Polaris RZR has a warning in the main gauge pod for low voltage.
For the Polaris RZR, if the voltage level is below the ranges defined below for more than 6 seconds consecutively then the battery warning will illuminate on the gauge. The 4 ranges are setup as follows:
0 10 RPM 10.5V
The Polaris RZR’s charging system is better than other UTVs at almost 500W:
Stator Output: Idle ~310W, Max ~475W.
Here are the parts I ordered:

I am typically not a big fan of digital gauges as they tend to look a bit more cheap, but for a voltmeter, I like to see the exact number clearly.
On the RZR, there is an orange wire with a butt connector that is used for a winch. This wire is hot only when the key is on (ignition hot). I connected the red wire from the gauge to this orange wire.
For the purple dimmer wire, I spliced into the green wire that goes to the factory headlight switch. This wire is hot only when the lights are on.
Here is what I have learned so far:
I have had the factory battery warning light come on while driving in the dunes at night before, so I am anxious to see what I learn from the voltmeter. I think the biggest draws will come from the cooling fan and the stock halogen headlights.
