Product Review

Battery not charging? Might be time to replace your rectifier or regulator, and why not replace them both at once with a part that will work better than the originals. This Rectifier / Regulator Combo will replace both your old rectifier and regulator. Unlike many other units, this regulator rectifier is designed to work with lead acid based battieries, including Gel batteries as well as lithium batteries. You must have a fully charged battery in perfect working order before installing a new regulator rectifier.

Dimensions: 82mm Long x 30mm tall x 80mm wide
Mounting Hole spacing - 66mm (measured center to center)

Note: The white 5 wire connector plugs into the stock wiring harness, replacing the old rectifier. The 3 male spade connectors plug in where the old regulator connected. Corroded / loose / damaged wiring is a very common cause for charging system issues, make sure all connections are clean and secure. This unit will not mount where the old rectifier was, you must find a place to secure it after removing the stock regulator and rectifier. The body of the unit does not need to be grounded.
