The unit is now running. He told me the common coming off the transformer had to be connected to the ground on the board. This unit was originally a standing pilot furnace that had been retrofitted. Customer told the technician it hadn't worked right since it was retrofitted by another guy quite sometime ago. After several attempts to get the previous guy back out to repair it, he got tired of waiting so he called my buddy. The unit is running ok now. Thanks for all the help guys!
