Yo! Anyone know the output voltage of the transformer in one of these common 175W "yard light" fixtures? My normal troubleshooting method would be to put a new bulb in and see if it comes on. I don't want to invest the money for a new bulb, if there is something wrong with the X-fmr or the photo cell. Thanks for all your knowledgeable answers and wild guesses.
