regulator question

the cavalier · 12-05-2011, 12:52 PM

HI!

I have recently tested my regulator rectifier after a few weeks of tending my battery every night to get it running. You see, the battery itself was not holding it's voltage over night. Well i spent $200 on a yuasa battery and am wanting to protect my investment.

turns out my regulator is not running perfect...

At 1,500 rpms it's producing an average of 14. volts. great!
at 5,000 rpms it's producing an average of only 13.8 volts... hmmm.
this means that the battery is getting some charge when i'm riding at speed.
My commute is an even mix of about 5 miles on the hwy and 5 miles of traffic lights.

my questions are...
is 13.8 volts enough to keep my bike charged at hyw speeds?
is this a sign of future failure?
Am I at risk of killing my new battery?
can i put this repair off till the spring?

anyone have a spare regulator rectifier?

Thanks for the advice!

There are no electrical accessories on this bike.

I did check for loss of current and also the generator coils. no problems.

Did you turn on the low beam?

I'm on my 3rd rec/reg........ Just replace it with the latest model. 13.8 is not enough.

New/good reg. runs 14.4/5 at idle no lights

14.4/5 at rpm lights/no lights

Two invaluable gages are a volt meter and oil temp (correct eng. temp)

A lot of people panic that their bikes are overheating because their cooling system does what it is designed to do. With an oil temp gauge you know what is really happening.

I mounted mine on the glove box

The battery killing issue is not an insufficient charge issue. The batteries get a shorted cell and then will take but not keep a charge. This can be diagnosed on a battery tester. There are disagreements as to the exact cause but spikes from the rectifier, how the starter draws, using a charger at more than 1.2 amps and jumping the bike are all possible causes. The 950 is famous for shorting batteries and seemingly worse with gel batteries. You may have an additional problem of low voltage in which case change the rectifier.

Go and price a Rec/Reg, there reasonably priced/cheep compared to all the fucking around. Everyone should should have one handy.

thanks for the replies!

i am now in search for a regulator...

I got one of eBay installed it and it worked perfectly for about 10 seconds. Total waist of money. The thing caught fire sort of. This stuff had a big rap through the Yamaha forums.

So I am on my third KTM and forth rec/reg. I've had my bike since new 6 years. Change my waterpump every 15,000km ... now 20,000km. Fitted a vacuum fuel pump..... and recently fixed my starter sprang spring. That was quite funny as I rang the shop and was quoted $1,080 for the part which includes the freewheel. The broken part looks like a spring from behind an oil seal..... reached into my bag of old unused seals and gaskets and found one that fit...... I works perfect. Cost = $0,000

Easy bike to live with. No other problems

K2m- which oil temp gauge is that and where/how is it hooked up? Sounds like a real good idea. Thanks

K2m · 12-08-2011, 09:56 PM

The gauge is a VDO water-temp from a boating shop ...... a discount warehouse place. I got the sender from the same shop. There is a little lug on the back of the oil tank. I drilled and taped it

It's been there nearly 6 years

I will have to dig for the complete reference, but I believe that a Yamaha R1 regulator will work far better because of the MOSFETs used internally. Requires the harness plug to be spliced but that is pretty easy. The R1 regs run much cooler and as a result typically will last a very long time. Voltage regulation also tends to be more in line with ~14.2Vdc.

Nice one Ken

This is nothing like the Chinese rubbish that I tried

The KTM ones do not last long enough. This looks to be a good solution to an on going problem.

Or maybe the kit

Might just grab one

How do you connect to the OEM loom? Did you find the manufacturer of the OEM brown plug the yellow wires connect to?
