Generator/Regulator rectifer problem - 2001 VFR800 FI ???

Hi all,

I'm new here so first off hello everyone :biggrin:

I have a 2001 VFR 800 FI Interceptor and it has been laid up for the last few months as I think I'm having some electrical issues with the bike. Bit of a long story so please bear with me, ok early last year when riding the bike the FI on the dash would flick on/off and the engine would cut out for n reason at all at the same time the key symbol light flashed. Bike would then start without an issues a few minutes later and I could get home. No cold weather or anything to factor in what the issue might be. This happened a few times so I brought it to my mechanic and when we took the seat off the bike we could see what the issue was straight away...............the main fuse, 30A, was melted and I mean melted to the holder. We changed the fuse out and eventually cut out that bad wiring and replaced it and all seemed to be good for awhile. After some time I noticed the battery was sounding very weak when starting and eventually it gave up the ghost and was dead as a dodo.

Last weekend I got a lend of a battery to try and get her up and running again, fully charged battery, with a bit if effort as she would not turn over and had to spray WD40 into all the switches on the handlebars and even on the rear brake light switch, it had ben standing in the elements with no cover so my fault really. Once switches sprayed and flick on and off a few times when the key was turned you could hear the usual fuel pump kicking in and the clocks spin over and then she started first time on the button

Anyway once up and running and let get up to temp and idle revs I noticed that when using the voltmeter to check charging current back to battery it displayed a whopping 17.4volts when running at idle with headlights.. Im thinking something major is wrong here as max I would expect is 15volts, am I right??

Hoping you guys can help shed some light on this for me as I cant wait to get back on the bike especially after hearing her purr over the weekend

Just remember if you are going to suggest testing he regulator or generator with the voltmeter please spell it out for me as if im a 3 year old as im totally clueless with this type of stuff :biggrin:
