I have a 2002 6th Gen VFR 800 with ABS brakes and approx.54,000 miles.
On Saturday morning the bike started fine. An hour later when I switched the ignition on all instruments and clock went blank. After leaving it about 5 mins the clock came back. Bike would not bump start but fired up first time when jump started. Suspecting a dodgy battery, I put a new one on today. Ignition on, fuel pump initialised and all lights and instruments came on. As soon as I pressed the starter button there was a click from starter solenoid area and all electrics died. Removed connection from battery reconnected it and same thing happened again. As bike started from jump start I assume starter motor and solenoid ok?
Please can anyone shed any light on this annoying problem?
What have you checked/diagnosed so far? Battery voltage? Fully charged battery? Clean connections? Jump when in parallel to a big battery (car/truck 12V)?
Any luck troubleshooting this issue yet? I have a 99 VFR with the same exact electrical problem you described, but it is intermittent and frustrating to try and diagnose. I replaced the battery and previously replaced the regulator/rectifier, but I continue to have the problem. I am looking to pull the stator next, but everything else seems to check good so far.
Check wiring, and connectors first. With an ohm meter. At operating temperature. Until you know for a fact that the wiring/connectors is not the issue replacing components is a fool's game, and expensive.
Simple, cheap, and easy fixes first.
Pro tip: stock Honda wiring is not very robust. I have bypassed all the stock charging system, and headlight wiring on my bikes. They are happy now.
