Motorcycle Repair: 1978 Honda CB550 Four Turn signals not working, turn signal flasher, lithium grease

Question
My turn signals will not come one and I have checked the wiring from the front and rear signal by connecting the battery directly to the wires for the lights and the turn signal lights will come on with direct power. When I turn the key on and use the switch, only a turn signal buzzer comes on, but no lights. I've also replaced the turn signal flasher and still no luck. I also checked all connections in the front headlight bucket and cleaned all connection points in the headlight bucket with sand paper and coated the connections with lithium grease.  Any help would be appreciated.

Answer
Mark ,
 Make sure that you have power into the t/s switch and power back out...trace your power wire back down the harness to the signal..I dont know what the wire colors are , but you should be able to determine that from looking at the t/s wires...You have a wire disconnected somewhere or a broken wire...prob each side of any connector or union with your test lite make sure that continuity goes thru the connectors..

HOpe this helps
