please help with my xt500 12 volt conversion

I just got a 1978 xt500. All of the electrical except magneto, points, and coil have been removed.

I want to convert it to 12 volts, without altering the stator. Then I will re wire the bike to have street legal lighting (headlight, tail light, brake light, turn signals).

I need a 12 volt regulator/rectifier combo with a one wire input (direct form stator) and a one wire output (12v regulated DC).

Will this work??

Thanks!

get that and a 20A circuit breaker. i ran a 12v halogen headlight & LED taillight with this setup. no rectifier or battery eliminator, but you wont need it. the LED will work on AC. only downside is dim light at idle.
no modifications to the stator.

Thanks plugeye! Very helpful.

The item you posted is just a regulator though, correct? I just regulates the AC current to 12v?

I was hoping to find a similar device that is both a regulator+rectifier.

I really wan to run turn signals, and regular automotive flashers only work with DC current. I do NOT want to run a battery though, just a small capacitor.

Does anyone know of a similar regulator+ rectifier?? I am not certain that the one i posted is also a rectifier...

I think I answered my own question. "Normal' AC to DC rectifiers do not work on floating ground alternators, like the xt500 has, with only 1 'hot' wire coming off of it.

I have also found some flashers that claim to work on AC power... so I'm just going to buy the regulator you suggested and run the whole bike on AC current.

The one you posted is definitely not a rectifier/regulator. Those will have 4 wires (for single phase AC input) or 5 wires for 3-phase AC input.
