Original post from yesterday on another forum:

So here's the info ii have

Battery 3-4yrs old
Charge 24 hrs I can ride it for about 3-4 hrs then she'll die at stop lights if I don't keep the reving it.

I'm thinkin its the battery because its old but my bud says it may be the stator. Then after doing a litte google search(which brought me to you guys) I heard a lot of this could be a regulator? Previou owner said he had a voltage regulator put in last yr but idk if that's what I've been readin about. The regulator I'm refering to is called RR for short by some people.

I bought a fsm(must have for any vehicle I buy) so I'll be checking some things out but I figured id ask you guys what your thoughts are. If I throw the charger on it in 24hrs I can ride and not have to worry about it for a few days as I don't ride everyday and I only ride for maybe an hr or so a day

New post from this morning:
Ok really neeed help now. Look what I found





Now I did all the tests according to the fsm and everything checked out fine. Only problem was the 2 yello wires(burnt 1s). When I probed those 2 wires just a little back on the harnessthe reading were right.

What could cause this? What should I do about this(besides cutting the connector off and redoing the wires)?

 

I have the exact same problem! Mine fried on saturday after a 60 mile ride. I would suggest going a buying a 2000 or newer GSXR 600/750 regulator, according to a lot of guys on here they are the ones that work best, just make sure the new R/R has a single plug and 5 wires the wiring goes as follows:
Honda Suzuki
3 yellow( charging) 3 black
1 Red ( positive) 1 black/red
1 green( negative) 1 black/white

Just cut the plugs off and solder the wires together according to the above list, Just be sure to heat-shrink everything and you should be good to go.

 

Yea I just got done reading all about that upgrade. Thanks. Never really fouind a straight answet about what wires connected to what wires though. Like how do know what yellow wire connects to what black wire??

 

I actually just got done doing all of my research and got my info from this post.

The yellow wires coming from the stator, and the black ones from the suzuki regulator are the charging wires, they are where the stator's power comes from to go to the regulator then the rest of the bike. All of the yellow/black wires are exactly the same and can be connected in any order, just as long as yellow goes to solid black. Hope this helps.

if the Yellow wires are the charging wire i would be looking into why they fried. the amperage was too high this can be caused by a bad battery though it will charge it may not work properly. make sure you do not have an excessive draw on the battery, hook a 20a amp meter between the battery and the red wire to see tha draw on your bike. I just had a friend who had an issue with something similar the difference was he was blowing fuses instead of melting wires. It turned out the LEDs installed had melted and the wire had touched the frame slider grounding out hs light when testing the 3 amp circuit it would draw 30+ amps. Hope this helps. battery is cheap and stators, regulators are not.

 

Definetly will have to look into the battery a little more. Just figured I saw some threads that had that same wire fry problem and figured its that part. The guy said he had that replaced last year with a new oem one but he also said my sprockets were 2 down in rear and 1 up in front and that turned out to be false.

How do you check the regulator itself? I tried probing the connectors while it was unplugged but didn't get any reading. Maybe I'm doing something wrong?

 

When your regulator goes, it allows one of two things to happen; one, an undercharge situation where it doesn't allow enough juice to everything resulting in your battery dying all the time when you ride. And 2, an overcharge situation, resulting in burnt fuses, and or burnt wires. In this situation, since the stator is not fused and the plug creates resistance, the connection burnt. You could be right about the excess draw, but the R/R is definitely toast.

 

If the wires are burnt up there's no need to check rr. That what happens when it goes out.

 

I had a voltage regulator go out on me, was draining and killing the battery, sending random voltage spikes all over. Ended up having to get a new battery after just buying a new one and also a new fuel pump cuz the voltage spikes fried it.

 

Voltage spikes and sags are not good for electronics or batteries, its best to just buy a new battery and new regulator.
