2008 Trx500fm 0 Posted July 1, 2022 I was wondering if anyone can tell me how many watts my 2008 Trx500fm produces and uses. I would like to install a led light bar, heated hand grips and maybe a winch I would like to know how big of a light bar I can install currently the bike is completely stock.

Goober 1,555 Posted July 1, 2022 (edited) The service manual will list a charging rate for certain rpm. Keep in mind it doesn’t list draw at idle. Your accessory circuit is probably rated at 10A. use P= I x E to determine maximum loading on that circuit: Power (watts) = Inductance (Amps) x Electromotive Force (Volts) for a 10A circuit on a 12 Volt system, expect the fuze to blow before you draw 120 watts. actually fuze probably won’t blow with temporary excursions to 120W. A fast blow wouldn’t tolerate them though Edited July 1, 2022 by Goober Share this post Link to post Share on other sites

I have heated grips, winch, and this lightbar on my 06 with no issues at all. https://www.amazon.com/gp/product/B00T4HPIGG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Share this post Link to post Share on other sites
