I'M GOING BY MEMORY HERE. I WILL RECHECK CONNECTORS AND VOLTAGES IN THE MORNING TO BE SURE THAT I'M DESCRIBING THE PROBLEM CORRECTLY.
I HAVE A 2004 SUZUKI SAVAGE LS650,
I WENT TO START THE BIKE AFTER IT WAS SITTING FOR A COUPLE DAYS.
THE BIKE DID NOT CRANK AT ALL.
INSTEAD I HEARD A NOISE AND NOW NO ELECTRIC.
FUSES ARE GOOD.
BEGAN REMOVING CONNECTORS TO ISOLATE PROBLEM.
COULD GET LIGHTS UP AFTER REMOVING MULTIPLE CONNECTORS.
BEGAN PLUGGING IN CONNECTORS.
LIGHTS STAYED ON WHEN SOME CONNECTORS WERE CONNECTED AND WHEN SOME WERE NOT.
COULD NOT ISOLATE PROBLEM TO ONE CONNECTOR.
AS I WAS CHECKING VOLTAGES, I DISCONNECTED ONE NEGATIVE CONNECTOR AND FOUND THAT THIS NEGATIVE WIRE WOULD SOMETIME HAVE A FLOATING VOLTAGE ON IT.
IT WOULD ACT LIKE THERE WAS CAPACITOR CHARGING AND DISCHARGING OR SOMETHING THAT WAS CAUSING THE VOLTAGE TO SLOWLY MOVE FROM 0 UP TO 13V. WHEN IT REACHED 13V I PLUGGED IT BACK IN AND THE LIGHTS WOULD WORK.
THEN WHEN TRYING TO RECONNECT OTHER CONNECTORS,
LIGHTS STAYED ON WHEN SOME CONNECTORS WERE CONNECTED AND SOME WERE NOT.
COULD NOT ISOLATE PROBLEM TO ONE CONNECTOR.
BUT EACH TIME THAT ALL THE LIGHTS WOULD GO OUT, I WOULD JUST UNPLUG THAT NEGATIVE TERM TO FIND THE SAME INCREASING VOLTAGE FROM 0 TO 13VOLTS WAS PRESENT.
I WAITED UNTIL THE VOLTAGE WENT BACK UP TO 13V THEN RECONNECT THAT GROUND AND SURE ENOUGH LIGHTS WOULD TURN BACK ON???
ALSO OHMED OUT THE IGNITION SWITCH, IT TESTED GOOD.
DISCONNECTED DIODE UNDER SEAT AND PROBLEM STILL EXISTED.
SORRY FOR THE LENGTH OF DESCRIPTION.
ANY HELP WOULD BE GREATLY APPRECIATED!
Many eletrical units on motorcycles need testing equipment that only dealers habve ,my advice is to take the bike to a electrician ,he will test each component and eliminate the parts that are working coprrectly .otherwise you could be searching for days to solve this problem .it maybe a simlpe thing like a basd earth .
