mosfet regulator

Postby goldminerusa » Mon Jul 23, 2012 10:53 am



I was reading a post at the NGW site yesterday about replacing the regulator on 1000, 1100, 1200`s with the regulator from either a 04-07 cbr1000rr or cbr600rr. Its a Shindengen model FH008EB and it doesn`t shunt excess voltage by converting to heat. The author says on his 1200, it raised the battery charge voltage from 12.4 to 14.3 @ idle. So, my question is if it raises voltage does it also raise wattage? If i swap one on my 1100 can i add more toys? or a couple of high wattage toys like a 60/100 H4 bulb or 55 watt driving/fog lights or ?

You are still limited to the maximum amount of power that can be generated by the stator.
The MOSFET technology will run cooler than the original.Faster switching and a bit more stable.

In your opinion is it worth upgrading? I understand they can found on ebey for 45.00$.

A clean running system is suitable.other than the new one being able to keep the volts up a little more at a idle,I don't see any benefit.the avaiable current will be the same.
I'd be inclined to use one to replace a bad one, but I'd rather put the $50 bucks into a set of LED driving lights.

Any time. You can only squeeze just so much extra out of the bike.it was never designed for anything else to be added on.Even the LTD version designed a little bigger system to handle the extra demand for power.
The best is to cut power needs with LED's and then you can put in more from the savings.

Captain: Scotty, I need more power. Scotty: But Captain, It canna` be done. You KNOW i`m heading for the conversion, but i`m a factory design purist at heart. What`s a po` boy to do?

If you are just concerned about idling at 14 volts just convert your lights to LEDs and your bike will idle at 14v or near that anyway.

It`s not a concern, i was just hoping for more watts to run more toys! However, i have read some post`s saying that LED bulbs cost on average $17 each, combine that electrical savings with the $45 mosfet regulator and i`d have plenty of juice for toys. Or so i`d hoped. Virgilmobile has cleared this up for me. I`ll consider the LED`s though. To you DingDong, I hunted up a set of air deflectors from a 1000 S, got them mounted and they have improved cooling on my `82 1100 S, Thanks for that.
