A simple question to ya. I have a dirtbike that is putting out 11-13v AC.
There's no battery on it, just a stator and regulator.
I'm thinking of powering a small 12v 0.27a PC fan. I remember putting a DC fan on my bike's power and it spun the fan but I just wanted to see if it would even work. Anyway I have burned out 3 different PC fans but using a rectifier rated at 200volts 15amp. Plenty sufficient and anyway I measured the voltage before the rectifier and it was just a 11.37v AC but after the regulator it idles at 28v and if I rev the bike it gets all the way to 48v 15amps.
Explains why my fans keep dieing. I think I'm just going to buy a bigger fan rated at maybe .81amps and just run it off AC current. Will this hurt the reliable of the fan and is there a reason why the rectifier is jumping the voltage up so high? Also the rectifier wasn't hot at all.
