my battery died and the wires on my voltage regulator are fried

[BYRD_IV]

I HAVE A 2000 GSXR 750 and i bought a new generator a new voltage regulator and a new battery. I changed everything and my bike ran fine for about a week then it died again. the wires on my voltage regulator were fried now and this is the 2nd time this happened. I found out the battery they sold me was for a 99 gsxr 750 and not a 2000 gsxr 750. could the battery be the problem and what is the right battery that i need. I really need help this is my everyday driver thanks.

Might been the voltage regulator or generator or got some wire touching somewhere causing the burn out, batt should be fine should be no differents between a 2000 or 1999 batt as long it is 12 volt but check the amps output of batt. you might need to go over the specs of our bike.

Not enough information to tell... As long as you connected everything properly, tested it properly a slight diff in battery should not matter. Most bike electrical systems are pretty fragile and need to be treated with respect.

What testing did you do?

[awayatc]

an incorrect battery will maybe not last as long as the recommended one, but burned out regulator wires point in a different direction.
When the bike was running did you check voltage output?
Other possibility is wires to and from battery/regulator etc that are not able to handle current.
This "bottleneck" creates heat...i.e the diameter of the wires is to small..(corrosion, breakage, rubbed through....) can you check resistance (ohm) .?
The less resistance the better... sounds you have to start all over again.
If you can't find problem yourself have an auto electrician look it over.
Bikes are quite simple and easy to trace (if you have it partly "stripped"
Good luck

i tested the battery, generator and the voltage regulator was new. i mean what else can i check. do i need a wireharness are could it be something as simple as a fuse. any thoughts even if your not sure it doesn't hurt to speak your mind.

was the stator new OEM suzuki or rewound?

oem suzuki

Like it or not - you need to purchase a multimeter and learn how your electrical system works if you have any chance of fixing it. Have a quick search on the net, there are a ton of trouble shooting guides - theres probably even one in your Suzuki workshop manual.

I can think of several things that could be wrong with it but without it sitting in front of me I could not even begin to have a clue where to start with your bike other than to say, if the wires are fried you either had too much current flowing and they got too hot OR you had a dodgy connection which generated too much heat which shorted something and then too much current flowed.

As I mentioned earlier, motorcycle electrical systems are reasonably fragile and easily damaged. They are also often poorly earthed and time and corrosion is their enemy, just replacing stuff is not going to guarantee a result.

Why?.....?

[Paul in NZ]

Why?.....?

Cos it was easier that figuring out what went wrong and he was in a hurry?? I dunno either..

[Motu]

He must be a politician - fix the result,not the cause.'Coz it's cheaper eh?

i found out that the wires from the generator to my voltage regulator were no good. the wire close to the plugs was still like new but the middle of the wire was shot to hell. so thanks paul and everybody that helped me. i'm glad theirs people out there that don't mind lending a hand.

Seriously - get someone with a multi meter to do a quick check of your system. At around 5000rpm I'd expect 70V AC between any of the phases from the alternator (3 white wires) and 14.5 to 15 V DC across the battery.

Make sure you keep an eye on the connections and keep em tight, clean and dry. Also, consider running aux earth cables from the frame to the engine and frame to rec/reg mounts and headligt sub assembly.

Good luck...
