Common Technical Issues: KAWASAKI EX250 Ninja 250R
BRAND: KAWASAKI
MODEL: EX250 Ninja 250R
YEARS: 86-87
CATEGORY: MOTORCYCLE
TECHNICAL ISSUE DETAILS
These 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. Common faults in this system: 1) Bad Connections in the system. We recommend checking all electrical connections in these bikes. The connectors are not that great, and the bikes are fairly old by now. Clean the connectors one by one with some contact cleaner and make sure the bullet style connectors are tight. 2) Regulator/rectifier failure. The OEM regulator/rectifier is a commonly failing part. 3) Stator failure. Causes are age, heat and vibration. Test and replace when it tests bad. We recommend using the fault finding chart in case of suspected charging problems: Fault Finding Guide This guide will help you diagnose the charging system quickly.
