Common Technical Issues: HONDA CB600F Hornet

BRAND: HONDA
MODEL: CB600F Hornet
YEARS: 04-07
CATEGORY: MOTORCYCLE

TECHNICAL ISSUE DETAILS
The 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 ESR587 has been completely redesigned and incorporates cooling fins, and a super heavy duty rectifier bridge. 2) Bad regulator/rectifier main connector. Check the connector on the regulator/rectifier that plugs into the bike wiring harness. You may find melted plastic around the pins.. This will cause poor or no charging and will also often overheat the electronic circuits inside the regulator/rectifier. This connector is not available aftermarket. If the connector is completely burnt up on the bike's wiring harness side you can install a different model regulator/rectifier (ESR531) and ask for the counter part to be supplied with it. Our sales staff will be happy to help you. 3) Bad connections inside the main fuse holder. Clean and check charging output again. 4) Stator failure. The stator fails regularly. Causes are age, heat and vibration. Replace when it tests bad. We recommend using the fault finding chart as you can find them on Fault Finding Guide This guide will help you diagnose the charging system quickly.
