Cheap Regulator/Rectifier Replacement

 

My 1999 SV had a history of killing batteries with its previous owners, and the bike sat for a while before I bought it. I replaced the dead battery with a new one, since the old one would not hold a charge(sealed batteries are known for their 'memory'). However, the bike didnt want to turn over after a few days of riding, and my headlight looked yellow and dingy. Some quick diagnostics with a multi-meter showed my charging system was generating AC power, but the regulator/recitifier combo was wasn't charging my battery at all. A new one prices around $200 from Suzuki. I found a similar looking one on eBay for a 1997 GSXR 750 that works perfectly, for around 20 bucks. Just about any one would work though, as long as it is a five-wire regulator/rectifier. Many manufacturers use a six-wire charging system, dont try to use one, the sixth wire is used to control the charging coils as a voltage regulator, and this system cannot be adapted to the SV's system!

 

The hardest part is getting the connectors to match up, which required unclipping the connectors from the stock wires and slipping them onto the wires from the new box. You can remove the plastic connectors by inserting a small flat-blade screw driver into the individual sockets and smashing an angled tab flat, so that the metal connector blade and attached wire can slide out of the plastic connetor housing. Its difficult for a first-timer to get one out, but after one is out and you see how they work, the rest are cake. Be sure when re-inserting the connectors into the plastic connector sockets that you re-bend the angled spot out so it catches and prevents the wire from pulling back out. Also, double-check the position of the wires in the plastic connectors, so that you dont have one wire not connected to anything(Suzuki used a four-pin connector for a three-pin job on the 99's, and switched to a six-pin on the newer models, but there is still an un-used slot). The order on the three charging wires doesnt matter, since they are the generator wires and all alternate current anyway. So, simply put the three common wires from the SVs harness connecting to the three common wires on the new box, in no particular order. On the stock box, they are yellow, but on the GSXR one they are all solid black. The only wires that matter are the two black wires with a white stripe and a red stripe. The red stripe is your battery 'hot' or positive, and the one with a white stripe is the ground wire. These didnt fit right into the stock plastic housing, so i had to cut the stock wires off close to the connector housing, and strip the ends of the respective new wires then solder them together. A butt-connector of the crimp type would work as well, but isnt as clean looking or weather-proof. The new unit is noticeabley larger than the stock one, but not much, and all that was required to mount it were longer bolts, the holes are the exact same. You'll find that there are a wide variety of these boxes that interchange with only minor connector swapping. Now my battery shows 13.5 volts at idle and my headlight is as bright as can be! No more dead batteries for a fraction of the factory replacement cost! Any questions on this article, please email me.

 

Happy SV riding!

For rectifier, mine was fried about a year ago..

Have been using the GSXR750 rectifier ever since. Battery still in tip top condition

 

Ok thats a valuable informations for the sv riders.

[ami422]

Hi Guys, Thanks for all the info.

 

well, i am using Suzuki Bandit's rectifier, Batt is new, according to Mechanic, its charging ok, but charging go down on high rpm(13+volts at idle). i think its same with the org rectifier.

 

lets see how it goes...

any one have any idea about how to check that rectifier is giving enough volts for bat's life?

[littlewing]

sounds like you had one spark plug coil fried. I had this before. Check if you only has one cylinder cold.

 

So bro hw much did it cost u to get it changed...

Which shop do u guys usually go too ar?

[adrianslacker]

Oh no...

 

you can't find the rectifier in the market anymore. If you can't find on the ebay, you're screwed. Prepare to dereg your ride...

:lol: :lol:

[KooTeowMan]

I go guan ho if parts are concerned.

Did we met before? Are you riding a SV?

[ahsnow]

thought of buying a sv400 not too sure izzit a gd bike can i have the link currently riding a s4 wish to try a difference bike so hope can get info from most of u guy here thanks 4 sharing with me

[Denden]

Oh no...

 

you can't find the rectifier in the market anymore. If you can't find on the ebay, you're screwed. Prepare to dereg your ride...

 

Now I know who to look for spares for the SV...

 

When is Ami422 deregistering the bikey?

Hi Hi... any one have tried the Battery from Ah Boy? which Brand should buy? and how much?(i heard ppl saying that Ah boy's battery not gog, fake one, true or not?)

Oh no...

 

you can't find the rectifier in the market anymore. If you can't find on the ebay, you're screwed. Prepare to dereg your ride...

 

Any SV spares to contribute?

 

Hey Denden! Take your queue number.

That's only applicable for McDonald Burgers.

[kazuhiko]

sv parts are pretty scarce. maybe we need to find alternate source to import spares parts..

[ahsnow]

hello so anyone can tell me is sv400 is a gd bike to get??

Do u see many SVs for sale?

If not, u might wana 'review' how come there's so little for sale..

Cos its a damn good bike!!! No one wana let go!!

Think there's only like 12 400ccs one available.

One is mine, 1 wif littlewing, 1 wif Orangdez, 1 wif adrainslacker, 1 with Mah motor, 1 in a motoshop in Tampines...

 

The others, status unknown...

 

Gd luck on ur hunt.

[ahsnow]

so is there any link tt i can have more info about this bike it seen i can't get any info of it

[kazuhiko]

[ahsnow]

thanks for the link may i ask some question i have found myself a SV400 but i found out tt it only have a single disk break in front so how is the breaking currenly i riding a s4 so just wish to find out more before i change the bike ??

[kazuhiko]

there are a number of class 2A bikes with single brake disk. I think the braking should be reasonably good. A few factors varies in an effective breaking such as brake pad, steel brake hose and brake master pump.

 

To conclude, a single brake disk should be more than adequate to stop the bike.

[ahsnow]

thanks for the info think i will try out the bike before i get it thanks for all the help anyway can i know how many liter of EO it need izzit 2 spark plug for the service??

[KooTeowMan]

One good way is to convince one of us to dereg their ride...

 

sv parts are pretty scarce. maybe we need to find alternate source to import spares parts..

[KooTeowMan]

2.3 litre,

2 spark plugs,

2 carburators.

 

If you want a bike that is cheaper to maintain than s4, this is it.

Cheaper, better, faster, nicer & rare... I made a guy crash because he can't stop looking at my bike while riding...

[littlewing]

another one is at aljuneid motorworks...bike shop at sims drive...silver color FWsomething.... shop selling at reasonable price i think..he say if nobody buy..wanna export redi...

btw may i know wat problem will this bike be having like S4 Rectifier is a problem very easy spoil

[Metalfyre]

saw denden n lawrence...haha

 

lawrence dun angry la...i blow blow get ur attention nia...no disturb u

a stronger engine brake also contributes and makes up for the lack of a twin disc brake system
