My 98 VFR800 has a flat battery. I had it in charge on my Optimate Battery tender and the red light stays on - says battery is F$%'d and wont take a charge. I removed the battery connections and put it back on charge and it charges fine and seems to hold a charge.
I suspect I have a parasitic drain or a wiring problem and I need to get it checked out.
Its been fitted with a later CBR Mosfet Reg/Rec in lieu of the OEM POS shunt that Honda fitted to the VFRs
I have to pull the fairings tonight to check connections but after that I belong to the "If you can't fix it with a hammer then you have an electrical problem" brigade:(

got an ammeter?
Put batt in.
With bike off, pull fuses one by one and put ammeter across the terminals in the box, see if any show up current flowing.
If yes, youve found the circuit. If not its an earth leak.
With a continuity meter, connect one side to ground, again, bike off, check (probe back of fuse) for continuity to ground. If yes, youve found the circuit. If you can live without the circuit, pull fuse and ride on. If no. You gna have to trace wire.
Pull fuse for circuit, chase the wire. Disconnect harnesses and check to ground again. Look for obvious fraying/rubbing etc.

Thanks for the help akzle...even I can follow that and I will give it a go.:2thumbsup
I think it may be the fuel pump or associated wiring.:nono:
Tried the bike last night - plenty of juice in the battery. Motor turned as usual but just would not fire. Either no spark at the plugs or the fuel pump may be faulty or the source of the leak. That gives me the first circuit to have a look at using your steps
Its a biatch having to use public transport - gets me home about an hour later than using the bike and I only live just over the bridge!

Hmm.. checked the bike last night. I was not chasing the drain at that stage - just wanting to get the bike going.
Pulled the fairings and all connectors/wires look fine. I can hear the fuel pump when I switch on so it seems to be working. Bike cranks over but the bike just won't fire. Battery seems to be holding a charge but it seems to go flat after very little cranking. Next job is to try it with another battery and see if the battery is dodgy and not generating a decent spark. If that is OK then I'll check that there is not a fuel blockage as it is almost like it is not getting fuel - maybe a blocked filter or similar.
Then it looks like it will be time to get a workshop involved. This is gonna be a trailer job so I need to find someone to pick it up.
