Premium Member joeszup Posted August 14, 2016 Premium Member Share Posted August 14, 2016 Keep in mind I know just enough about electricity to not electrocute myself. With that said, I just installed the OEM heated grips on my FJ. According to my handy multimeter, the charging system pushes 14.3V, while the battery is a 12V. So that means there is enough charge to run the bike and ... how much more? With the heated grips, whats the power draw? Can I add a heated seat too?

Premium Member builderbob Posted August 14, 2016 Premium Member Share Posted August 14, 2016 It's not so much about volts as it is about amps. I don't know what the FJ's output is, but if you can find out what it is, subtract the draw form your lights and accessories form the output of the stator and you'll have your answer.

Premium Member wessie Posted August 14, 2016 Premium Member Share Posted August 14, 2016 the stator output is 415 watts how much current does the your proposed heated seat use? Sargent say 46 watts per seat so my guess would be it will be okay, especially if you use a heat controller so the heating element is not often drawing full power This signature is left blank as the poster writes enough pretentious bollocks as it is.

Premium Member wessie Posted August 14, 2016 Premium Member Share Posted August 14, 2016 Stator output figure is from the factory workshop manual. Sargent website provides the spec. of their seat heaters. This signature is left blank as the poster writes enough pretentious bollocks as it is.

He's referring to the service manual used by technicians to work on the bike. Some of us were able to procure it, but it's not something that comes with the bike.

I find the coil resistance, but don't see stator output. Or is that a calculated value? Link to comment Share on other sites More sharing options...
