Regulator Rectifier - Fits Yamaha DS7 RD250 RD350 RD400 R5 XS1 XS2 XS400 XS650 TX650 - Lead Acid, Gel, Lithium Battery Compatible

Regulator rectifier for many of the 70's Yamaha's with points type ignition. Battery not charging? Might be time to replace your rectifier regulator. The battery must be fully charged and in perfect working order before installing a new regulator rectifier.This unit has a very consistent output and runs cooler than the original part due to the modern heat sink. The stable voltage output across the RPM range keeps the battery charged so you can ride with confidence!Note:This unit replaces the stock regulator and rectifier which were commonly 2 separate units on most early points type ignition systems.Note: Corroded / loose / damaged wiring is a common cause for charging system issues, make sure all connections are clean and secure. If the stock connector is brittle or melted and the terminals are corroded, it's best to replace them before installing the new part. This unit might not mount where the stock part was, check dimensions above.Note: It is strongly recommended to isolate the charging issue prior to replacing the regulator / rectifier. With a bad battery, stator or wiring issues, a new RR will not charge the battery. A faulty stator or wiring can cause damage to the RR.Wiring:5 Pin Plug3 white wires - Phase input from stator1 black wire - Ground1 red wire - Positive2 Pin Plug1 green wire - Switched ground from alternator field1 grey wire - voltage sensing input from ignition switchFits Yamaha:DS7 - 1972RD250/A/B - 1973-1975R5 - 1970-1972RD350/A/B - 1973-1975RD400C/D/E/F - 1976-1979XS400/D/E/F - 1977-1979TX650 - 1973TX650A - 1974XS1 - 1970XS1B - 1971XS2 - 1972XS650_2F - 1979XS650B - 1975XS650D - 1977XS650SE - 1978XS650SE-11 - 1978XS650SF - 1979XS650SG - 1980

• Regulator rectifier for many of the 70's Yamaha's with points type ignition. Not for CDI type ignition that was original to later models. See the fitment below.
• This unit has a very consistent output and runs cooler than the original part due to the modern heat sink. The stable voltage output across the RPM range keeps the battery charged so you can ride with confidence! See description for details.
