2008 RZRVoltage Regulator Relocation
Tired or the battery warning light blinking on your 2008 Polaris RZR? The 2008 Polaris RZR (all generations) have a problem keeping the battery voltage up with just the radiator cooling fan and stock halogen headlights running. If you add more lights or other accessories, you will most likely have even more problems.
A big part of the problem is your voltage regulator overheating. The problem with the 2008 voltage regulator is the location does not get any airflow and the regulator overheats. Once the regulator gets hot, it no longer charges the electrical system.
For 2009 model RZRs, Polaris moved the regulator up front by the radiator so it could get some fresh air and cool more effectively.
The best solution for your 2008 RZR is to relocate the voltage regulator up front to the same location as the 2009 model.
You can cut & splice the wires to add more length. Just make sure that your connections are solid and you shrink wrap the areas that have been cut.
Or if you are at all concerned with cutting into your factory harness, there is another option. Autotrend EFI has a plug and play harness that makes the job really easy. Not cutting is required. The Autotrend harness uses factory Delphi plugs to create an extension that makes this upgrade a piece of cake.
You can order a mount for the voltage regulator from Polaris that they use for the 2009 RZRs. The part number is PL5252587 – BRKT Regulator Mount. They retail for $2.25.
The two screws on the regulator have a Torx T25 head. Remove them, then unplug the two Delphi connectors and one bullet connector.
Be very careful drilling the holes so you don’t go all the way through and puncture the radiator.
