Series regulator/rectifier

[fastbysuzuki]

Hi, I have been looking for a series regulator that is rated at a minimum of 40 amp if anyone knows the model could you let me know.
i know Jim a while back did a list ( I think) but I cannot find it.

The Shindengen SH-847 is the new kid on the block. 50A capable.

Heyehe... Shindengen have finally upgraded their website from Window 98.

It's been fitted to V-Stroms for a few years now.

Jim was a compufire guy.

Since the SH775 hit the market it's been the go-to unit here on GSR. Not sure how much amperage it can handle but it's more than enough for a GS bike. The SH847 is rated for even higher current but they are more expensive.

What are you running that you need 40 amps? Bike? Charging system? ???

The Shindengen SH-847 is the new kid on the block. 50A capable.

And it's a fair bit bigger than the SH775, too.

Haven't checked the prices, but I have seen a few on eBay.

The 775 is rated at 35 amps, the 847 is rated at 50 amps. As I recall, the max output on a GS is about 35 amps, so the 775 is near-perfect.

Fastbysuzuki, once again, what is your application? If you are hoping to put on a 40+ amp regulator because you have added more lights and/or accessories, it won't work. The R/R does not make power, it only controls what the stator generates. As mentioned, the GS stators are only capable of about 25 amps.

Hi all, thanks for the reply's I am thinking about buying a Honda vfr800 having read quite a bit they seem to have rectifier problems I thought I would research for a series rectifier I belive the vfr is rated around 40 amp

Hi everyone, I put a SH847 on my bike, it is probably overkill for a GS but might be good for the VFR. The 847 has a huge footprint and might be difficult to mount on a bike with a air box. I put mine under the seat where the air box would normally go. On the plus side I get a constant charge of 14.3 volts with the headlights on and 14.5 volts with them off , even at idle, don't know if the Sh775 does the same thing. I bought mine at roadster cycle , the owner seems to know his stuff. They call the SH847 the stator saver because you can run it with almost no load ( race bikes) . I bought it because I was running LEDs but like I said probably overkill.

The Compu-Fire in my signature line is 40A. It is generally more expensive but also smaller than a lot of Series R/R's. It has been in the bike 9 very close to 10 trouble free years.
