Hi, I've got a 2015 speed triple 94r which I've had for a few years Issue started last week.... battery reads 12v while sat there but when i turn the ignition on the voltage steadily drops to near zero over about a minute And then the bike won't start. When the ignition is switched back off the voltage steadily rises again. Just bought a new battery and it does the same thing. Also put a new voltage regulator rectifier on it two months ago and took her to France last month and all was fine. Any ideas ??
Any way you can hook an amp meter ? Sounds to me like you have a short circuit, finding it is going to be interesting I would start disconnecting stuff and suspect anything that gets really hot , even a wire, so it can lead you to the problem
If the battery reads 12v with no load then it's in a low state of charge. A min of 12.6v when fully charged and 14-14.5 with the engine running. Every circuit, other than the starter motor, runs through a fuse of some sort. The sort of fault which could completely drain a battery in under a minute would blow a fuse long before that! I would expect the ignition circuit to draw no more than a few amps.
Had a thing some years ago with my ZZR1200. Started blowing 20A fuse and finished up coming home on a truck from France. Bastard Frogs were too busy whining about the shit World Cup they were having....anyway turned out to be an aftermarket screen l fitted was causing high resistance in a loom in the nosecone. Didn't even cut the wiring or insulation, just trapped it, but turning on was instant death for the fuse. If l've read you correctly the battery does recover so l'd go with a parasitic drain linked to a live circuit. Odd it doesn't take the fuse though.
Shorted chaffed wires near the headstock maybe? Charge your battery up as has been pointed out, 12v is no good, 12.6v is.
@Ivor The voltage is not what you need to check it is the amperage. But it does sound like something is draining the Battery like a positive wire touching metal. And to e sounds like around the headstock could be the culprit. Or the ignition switch shorting out.
Had a little play with the 94r today . Found the main 30amp fuse and holder all melted and stuck together ! Still not sure what's caused it but I can't find anything else wrong with it. Clamped a new fuse across the terminals and all seems fine. Starts OK. No voltage drop and runs OK ?? Need to get hold of another triumph 30amp fuse holder from somewhere.
Strewth mate, that's a codder. You could probably get a fuse holder from Halfrauds or similar and splice it in for at least a temporary fix and see if it behaves. Just bung in place with a couple of zip ties or a blob of Araldite....
Also I've just checked and I'm getting a 12.5v recharge rate when it's running . Guessing that should be nearer 13.5v , so may need a bit more investigation
Still having trouble with the charging rate and flat batteries , i'd already changed the voltage regulator/rectifier so pulled the stator out and one of the copper wound coils looks cooked. I couldnt find any loose or bared wires so petty sure this is the problem . Anyone got a link for a descent reliable brand so I can buy a new one ?
