Common Technical Issues: HONDA CBR900RR Fireblade

BRAND: HONDA
MODEL: CBR900RR Fireblade
YEARS: 93-95
CATEGORY: MOTORCYCLE

TECHNICAL ISSUE DETAILS
These CBR models all have a permanent magnet battery charging system, consisting of a stator with three output wires, which feed into a regulator/rectifier. This unit rectifies the AC into DC and regulates this DC to 14.5V to ensure proper battery charging. The output from the regulator/rectifier connects to the battery through a main fuse. Common faults in this system: 1) Regulator/rectifier failure. The OEM regulator/rectifier is a commonly failing part. The unit uses the frame rail it is bolted to for heatsinking and therefore has no cooling fins. Also: the output from the stator is fairly high putting a high thermal load on the regulator/rectifier. Our new regulator/rectifier has been completely redesigned and incorporates cooling fins, and a super heavy duty rectifier bridge. 3) Stator failure. The stator fails regularly. Causes are age, heat and vibration. Replace when it tests bad. We recommend using the fault finding chart. This guide will help you diagnose the charging system quickly.
