Arctic Cat released a service recall for the XTZ's. They put the voltage regulator screws in backwards which is causing the screws to wear holes in the battery. Here is a copy of the text of the bulletin for those of you that aren't able to make it back to the dealer to have it done.
Date: January 9, 2009 Product Line: UTV
Bulletin No: 2009-6-02 Subject: Voltage Regulator Mounting Screws
Affected Models: All 2009 Prowler XTZ within the VIN range of 305109-305693.
What is the reason for this notice?
It has been determined that the machine screws securing the voltage regulator are improperly installed
and need to be reversed.
Condition: Both machine screws securing the voltage regulator to the battery box were
installed incorrectly which may cause the battery to leak acid.
Solution: Reverse both machine screws according to the instructions in this bulletin.
What should you do?
