Stator Output?

Does anyone know the stock stator output on a 79 GS750E? Just want to make sure I can run heated gear and charge phone and extra lights and GPS if need be. Thanks!
 
In the vicinity of 250 watts, assuming stuff in good working order. Of course you have done charging tests to verify this.
Do you know if you have 12 or 18 pole stator?
 
So do we know if thats 250 of usable power or is that total power?
 
That would be TOTAL power.

Running the cell phone and GPS will be no problem at all.

Running heated gear depends on how much of it you have and whether you have a digital thermostat.

Extra lights are "iffy", but your chances are improved if they are LED units.

Thanks for the input. Ill have to do some math and digging to see what actual usable power is. Id guess around 100 watts
 
Member 'posplayr' has done some research and testing to find the capacity, but each bike will be a little bit different. I think he found that the ones he tested were capable of about 22 amps (at 14 volts, that would be 308 watts). If you have an amp meter, you can get a feel for how much the bike is using, but you have to be careful where you take your measurements. You can use jumper wires to add a load (spare headlight) to see if your charging system can still maintain about 14 volts. With additional load you may find that you have to keep the engine over 4000 RPM (or so) to maintain voltage, so you might have to adjust your extra load based on engine/road speed. A bit of a hassle, but if you really want to do it, it can happen.

HoHoHo...
When I was using my other GS with the twin lights, it was all fine and dandy and I was enjoying the extra output on the motorway down into London. After about an hour or less of stop-start-go London traffic the battery was dying... Off the motorway, the output of the alternator wasn't enough to supply the extra 55W. Luckily, it was easy to pull the connector to one of the lights and carry on, still with a perfectly adequate light.
