Ok, I'm trying to install a HID headlight on my snowmobile. The stock headlight is powered by a 12v ac line. My plan was to install a bridge rectifier and a capacitor to power the HID and I have a timer relay hooked to a battery to ignite it. I can not use the battery as a powersource because the charging circuit only puts out ~2amps.
So I thought that I could intall a bridge rec and get 12vdc. But here is what happens. After hooking up the bridge I measrue ~12AC on the input and 12vDC on the ouptut. If I swith the meeter to ac and measure the outputs I get 20+VAC.. I ran across this problem because I installed a large cap across the output and then measured the voltage and got 24vdc. I have tried three different bridge rectifiers but get the same results. What am I missing here? I'm usng a 35A 200 PIV Bridge. Its from allelectronics.com pn FWB-352.
I'm totaly stumped on the summing of the voltage. And ideas?
