wheelhorsejoe 4 #1 Posted February 1, 2021 (edited) can a wheel horse 416-8 electrical system power a 150w defroster? The engine is a 16hp K-series engine. Thanks Joe Edited February 1, 2021 by wheelhorsejoe 1 Share this post Link to post Share on other sites
Handy Don 12,163 #2 Posted February 1, 2021 (edited) Onans have a 20 amp alternator (20amps @12v = 240w). Remember some is going to battery charging and to keep the plugs sparking and maybe lights?! Edited February 1, 2021 by Handy Don Share this post Link to post Share on other sites
Maxwell-8 4,275 #3 Posted February 1, 2021 (edited) pff, that whould be the max i would wanne ask from it, headlights 60-70w, ignition system some, want to charge the battery,etc and that 20 amps is in high rpm. I reccomand installing a car or atv alternator When you install an extra alternator: welcome heated seat Edited February 1, 2021 by Maxwell-8 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,033 #4 Posted February 1, 2021 Kohler mostly likely has the 15 amp charging system so max = 180W. (Volts x amps) That is not leaving enough for lights, ignition and battery charging. Garry Share this post Link to post Share on other sites
roadapples 6,983 #5 Posted February 1, 2021 Turn on defroster only when needed for a few minutes. Then turn off. 3 1 Share this post Link to post Share on other sites

horseyheaven 112 #7 Posted February 2, 2021 I use two battery operated fans in the cab of my 520HC. They work well for keeping my breath from fogging the windows up. The ones I bought are able to clamp anywhere you want and can be swiveled\angled to hit in different areas. I went this route because I did not think I would have enough charging system for a defroster. I just searched battery operated fans on the internet. 1 Share this post Link to post Share on other sites
