SV 650 electrical problems

[Pittenger5]

Still trying to fix Leeza's bike, and since mine is broken now, we need a bike to commute on.
Anyway, there seems to be a power leak somewhere that drains the battery somewhere, so I left the positive connector connected (brand new battery btw, fully charged) and when I run a multimeter between the negative terminal and the negative lead I get a reading of 1.230 mA. When I started pulling fuses, the only one that made a difference was the one labeled "Meter". When I pull that one the reading drops to .745. I'm assuing this is probably the cause of the battery drain, but is that much of a drop enough to explain it? Or should I be looking elsewhere as well. The service manual says anything over a 1.0 can be considered a battery drain. So I assume thats it.
And assuming thats it, what should I be looking for to fix the problem without just running without the fuse. From an internet search it seems to be anything from the entire speedo, to simply the trip meter.

id start checking the wiring going to the dash. could just be a chaffed wire thats grounding out. put the fuse back in and set up the meter again, and start moving wires around that connect to the dash. if it is a grounded wire then moving the wires around could , hypothetically' unground it and make the meter reading change

what year and model SV?

Hmmm...have you tried unplugging the harness from the back of the meter to see if that same amperage drop occurs? That will help ensure the drop is coming from the meter itself and not somewhere between (there's not much in between, but still, always good to be systematic with stuff like this).

It's going to be tough to determine which circuit of the meter the draw is coming from without a clamp on ammeter. If you have a clamp on meter, you can grab the wiring diagram and isolate where the draw is coming from.

Not sure it matters though, since the meter is a printed circuit board. I think you'll have to replace it to fix anything...unless you want to just disconnect the leaking circuit.

BTW: I don't know what the static amperage draw of the bike should be. I'll check on my bike and post up, but the harness has been modified.

[Pittenger5]

Its an 01 Oxx, not sure which model, think its just the regular SV whatever.

[loudog]

Oh, sorry, I thought it was a 2G.

I just check my '06 though, and the draw was 0.69 mA with nothing on. So, it sounds like .745 mA is kosher.

ill assume it naked then (not an S with a fairing). id check the wiring. most of it is probably in the headlight bucket. maybe just a wire thats rubbed through.

[Pittenger5]

Yup, checked the wiring into the headlight, got it narrowed down, theres a connector when disconnected it drops again, just gotta figure out what connector it is.
6 pin
Got a pink wire
red with white stripe
black with green
Black with yellow
Black with blue
and orange with red

[Pittenger5]

Or is it possible to test all 6 connectors individually easily with a voltage meter

[loudog]

If you figure out how the wires plug into the harness, you can disconnect them one by one until the drain is gone.

The manual tells you how to do it for the 2G SV. If it's the same for the 1G, you just need a tiny screwdriver to press down a tab, which releases the wire.Then you can snap it back in when needed. I don't know if your SV has the same system though.

Can you borrow a working wire harness for testing purposes?

I remember NateDog was stuck with a wiring issue for a while. Ended up grabbing a used wire harness in eBay for like $80.

This sounds like corrosion in the ignition barrel to me. Does that connector go to the ignition switch?

Email address to send you over a copy of the wiring diagram?

Fitz

Thanks, but got the wiring diagram, just cant figure out where it goes to, or which to check

[Pittenger5]

Ok so I found out what the cables are.
1. Speed Sensor (+)
2. Speed Sensor (Signal)
3. Ignition Coil (signal)
4. Battery (+)
5. Oil Pressure Gauge
6. Water Temperature Switch

Couldnt pop the wires out one by one to test it though. Any other suggestions before I have to pony up to have a mechanic look at it?
And no spare wire harnesses to try with it

[loudog]

Damn. Are they not poppable, or are they giving you trouble with the release?

Another thought, you could narrow it down a bit by taking out fuses. It'll depend on how many of the potential problems are on the same circuit, but there's a chance you could figure it out there. Pull a fuse, check current draw...pull another, check current draw, etc.

Not poppable that I could see, and didnt wanna push or pull too hard.
Tried the fuse dealie, the one that made a difference is labeled "Meter", but I cant narrow down exactly what that one does.

[BostonSVkid]

Why not cut the wires to figure it out. When you figure it out, cut all the wires and just solder them back together. I did this on my old SV for other reasons and its not bad.

Yeah, the poppability on my SV isn't outwardly apparent, you really have to look in there with a flashlight and poke around with a tiny screwdriver....then pull with some good force.

Could you post a photo of your harness connection? Or have you checked the manual re: poppability?

I think popping, if possible, is your best bet aside from the inevitably expensive trip to the shop.

[TheIglu]

Unplug the harness in that location. Run one leg of your multimeter to ground and the other to each pin on each side of the plug. Once you find which one/side of the harness if it leaking current via, you are on your way.

[Pittenger5]

Which multimeter setting do I need to use for that?

[TheIglu]

Ohms (resistance)

[Pittenger5]

So when I do that, a couple of the wires jump momentarily to like 700 then back down, one jumped to like 1900, the others did nothing. Which ones should I be looking for, or did I do it wrong again?

[TheIglu]

The ones that didn't do anything aren't letting current pass.
