About This Product
Standard starter relay with diode. Replaces OEM 31504-91A. Fits late 1993 to 1999 Big Twin, Twin Cam, and late 1993 to 2004 XL Sportster models. The diode clamps voltage spikes before they reach the ECU and other electronics. Contacts and coil are the usual failure points on these. Check your old relay for burnt terminals. This one bolts straight in.
Manufacturer part number: MC-RLY4.
