Description: Regulator / Rectifier - Yamaha DS7 RD250/350/400 R5 XS1/2/400/650 TX650 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. Unlike many other units, this is designed to work with lead acid based, gel and lithium batteries. 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! All units are tested prior to shipping for quality assurance. Includes industry-leading 1 year warranty. Specifications: Dimensions: 68mm length x 80mm width x 25mm height Mounting bolt spacing: 64mm (Measured center to center) Replaces Yamaha Part Numbers: 1L9-81910-50-00, 256-81970-11-00, 278-81910-22-00, 278-81970-21-00 Note: This unit replaces the stock regulator and rectifier which were commonly 2 separate units on most early points type ignition systems. We have a 6 pin terminal set and a 3 pin terminal set if you need to replace the stock connections or to adapt this unit to your harness. 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 Plug 3 white wires - Phase input from stator 1 black wire - Ground 1 red wire - Positive 2 Pin Plug 1 green wire - Switched ground from alternator field 1 grey wire - voltage sensing input from ignition switch Fits Yamaha: DS7 - 1972 RD250/A/B - 1973-1975 R5 - 1970-1972 RD350/A/B - 1973-1975 RD400C/D/E/F - 1976-1979 XS400/D/E/F - 1977-1979 TX650 - 1973 TX650A - 1974 XS1 - 1970 XS1B - 1971 XS2 - 1972 XS650_2F - 1979 XS650B - 1975 XS650D - 1977 XS650SE - 1978 XS650SE-11 - 1978 XS650SF - 1979 XS650SG - 1980 4into1motorcycleparts • Store Policies
