I am not an electrician and do not profess to be! I completely redid incl painting the topside and mast. In the process, I replaced the running lights and wrecked the circuit. Lke a dummy, I never ID'ed the wire or wires connecting the stearn, port and starboard lights. I believe, and this is where your help would come in. Thehot wire connecting the lights back to the master switch and a positive and negative runs to the battery. A SINGLE wire runs to the lights and the negative comes off the master to the battery. I don't mind being electrically challenged but insist on not burning up my boat. An no, I don't feel I need to find a master electrician! Your Knowledge and experience is greatly appreciated.
