Does anyone know the alternator wattage output on a 2001 750 Nighthawk?

I've not seen an exact number that I can remember, but the guys on the Yahoo mailing list say the alternator doesn't put out much more than the bike needs to run. IIRC there's enough extra to run a heated vest or gloves or maybe a set of foglights.

330 Watts

You have about 10 amps available, but you will not charge well below 3000 RPM if you use them all.

I replaced all my lights except headlight with LED's and had enough left to run 2 x 30Watt Auxiliary lights without any issues. I originally had 2 55W aux lamps, all the rest of the lights stock, and it had a little trouble keeping up below 3k rpm. At an idle, the volts dropped to about 12.

With the LEDs and the 30w aux, I stay at 12.7V at idle and charge well off idle.

I have a charge Guard on the bike which reads Amps and Volts, so I learned quickly what worked.

I need to amend this. It is actually 220 watts. It's in my OM.

Still, you have about 10 amps to play with or 120 watts.

Did you have to put any kind of load ballast or anything on your bike to use the LED signals?? I know on some bikes they can flash real fast.

I have been thinking of opening up one of those sorta oval LED Brake lights they use on trucks and remounting the circuit board in my stock taillight housing. What did you use??

I have the Kisan signal Miser. It replaces the stock flasher and has a number of nice features. It's pricey, but gives you automatic turn signal cancellation, four way flashers, rear running lights.

It's about $100.

Putting resistors in doesn't reduce the current draw. It makes the stock signal flasher work with LEDS, but no reduced current benefit.

I checked out that Kisan Signal Minder and man that is one sweet piece of kit, but outta my buget. I think I'll forgo the four way flashers and I can cancel the signal myself.

The stock flasher has ground / 12v input / and load pins. This LED flasher I found has exactly the same pinout for $12.95, all I have to do is make a wiring adapter.
