Potentially not the usual R/R battery dead thread!

Hi all,

Right, I have a very peculiar problem with my SV and hopefully you guys might know what on earth is going on. The bike is a 99' SV650s UK spec.

First up the bike started to be a bit laggy on starting, I've got heated grips on the bike so assumed that maybe the grips were running the battery down on short rides so I rode with out them on for a while to see if it helped, it didn't.

Next up on Saturday morning I started the bike and rode down the hill from my house, when I arrived at the first roundabout the bike cut out, doh! After pushing it to the side of the road it seemed that it was completely and utterly dead, when the key is turned in the ignition the lights on the dash didn't light and my old school data tool immobiliser LED wasn't flashing. After a long mission getting a mate to come and help me out we did all we could do at the time and went and bought a new battery from a garage, we got back to the bike, put the new battery in and it fired instantly, problem solved! Not.

Later that day after riding around with the lights on and starting it a couple of times I decided to risk the ride home, then, at 10pm I pulled in to Watford Gap services for a little breather and it died again, same symptoms as before.

Anyway, the AA came and took me home and I put the battery on charge overnight to see if I could figure it out. This morning I went out to the garage to check things out and the battery is reading 12.98v on the multimeter but the bike is still dead to the world. All the fuses are still intact and there is no obvious reason for this lack of life. The strangest thing is that the symptoms were identical two days ago and it was fixed (briefly) with a new battery and although the battery says it's charged, nothing is working.

Painful.

If anyone can shed some light on this I would be very grateful as I am a little confuddle to say the least.

Just to clarify have you checked the main fuse on the solenoid?

Even if that's OK, I'd continue my fault finding search in that area, the four pin plug at the rear side of the solenoid carries the battery supply to the ignition switch.
If everything is dead then the fault lies somewhere on the line from battery-solenoid/main fuse holder-ignition switch-fuse board, and the associated wiring thereof.

Yep checked the fuses. I'll keep trying to figure it out and at some point will have to admit defeat and drop it off at a garage. Bummer, I'm properly skint at the mo.

Get the battery tested, as it maybe fubared. Mine used to cut out when the battery was on it last

Well, the plot thickens.

I've just been out to the bike to have another bash (almost literally). I started out by trying all the same stuff again and got nothing. I then removed the battery and connected my car jump leads to the bike terminals and still got nothing. I pulled out the mains fuse to take a look at it and it seemed fine so I shoved it back in. Then I reconnected the car battery and for some reason everything seemed hunky dory. I then put the battery back in the bike and it fired straight away. WTF has never been a more appropriate collection of letters. So this means that the battery wasn't flat at all but the last one definitely was as it wouldn't even light an LED indicator.

With a multimeter the battery reads 12v ish and when the engine is running it reads around 13v plus or minus a little. Do you think this still sounds like a r/r issue or is it something much deeper? I'm not exactly filled with confidence about riding it that's for sure! I'll try some wire wiggling and see if I can deliberately make it die and hopefully I'll be slightly further on.

Mission.

12v isn't enough to turn the bike over. A good battery should measure 13 to 13.2v. A 1 volt drop is enough to not start the bike. I'd guess your battery is dead.

I would certainly concentrate on checking/cleaning the wiring loom on R/H side around the battery, I had problems with weak lights and the battery not getting a decent charge a few years ago, no stopping dead luckily. One reg/rec later (cos' everybody said typical Suzuki. . .) which made little difference, at my wits end one careful cleaning of all those connections gave me back the missing volts! I wish I had been on the forum then. .

are the battery connects secured correctly?

It doesn't sound like RR. They make the battery go weak.

No life at all suggests poor connection somewhere. Check bits sid squid recommends, also earths, also in loom within 6" of fusebox there is a crimp connector on permanent live connecting regulator and ignition switch to the main fuse (hence battery) these are just wrapped in tape and can rot.


Annoyingly, you'll have to make it fault and then chase the fault out from the battery. Get the tank off and plastics off, switch it on and then start pulling and prodding the loom until it dies.
