Rectifier/Regulator

[swinging_simian]

Morning all!

I finally got my SV back on the road after. Long story short... moto-racing.co.uk supplied me with the wrong link(too narrow) for my new chain, which ended up breaking the new chain tool I'd bought to do the job :/ moto-racing maybe cheap, but their customer service is non-existant and they cost me more money GRRR!

Anyway, 4 days after it's back on the road it fails to start. One click, then no dash display at all. I had to recover the battery from virtually dead before the MOT, so I whipped it out to check and my charger reads 'green'. I plugged it back in and checked the connections on the relay and it starts up. I suspect this may have something to do with putting it on charge for a few minutes.

I did they head light test, by revving the engine, and they didn't get brighter. So I'm pretty sure it's the rec. But I have a multimeter on the way to do some more tests.

....to the point. This is the 2nd time the rec and battery have gone. This post (http://forums.sv650.org/showthread.php?t=151988&highlight=battery+problems) mentions getting a replacement with a sense wire.

Does the original svk4 part not have a sense wire?

I'm pretty sure the CBR600RR part has a sense wire..will this fit the svk4?

Any input much appreciated.

Okay, time to bump this with some more info.

I got the multimeter on it just now, measuring between the two battery terminals:

Ignition Off: 12.62V
Ignition On: 12.02V
Engine running: 13.6V
@ 5k RPM: 14.5V
@ 7K RPM: 14.5V

So this is not a problem with the rectifier, right?

Is that with lights on?
If so that looks healthy to me. 14.5 is right where you need it. This would suggest it is just a dud battery.

Yeah, with lights on, and I've just re-tested the lights while blipping the throttle and they do brighten, but only just. I think a combination of day light and 'bright' bulbs made it hard to see.

So the battery is knackered, even tho' I managed to revive it with my optimate.
What an ****. Better than paying the shop to look over it for me tho.

As always thanks very much for the feedback. You guys have saved me a lot of money.

You never know it might "come back to life" with a bit of use, but that's usually just a temporary respite.
