My 92 K75S will not start. I found an accessory wire on the positive battery terminal intermittently shorted to the battery hold down bracket. The battery seemed to be dead. When checked without load it showed 12.76 volts. When the ignition key is turned to "on" position and before touching the start button, there is a very low sound coming from under the gas tank (perhaps in the relay box) and the RPM gauge goes up as though the engine was running. Lights do not come on.
I installed a different battery. Same thing occurred.
I charged both batteries and reinstalled one. I turned on the ignition key and the lights came on. I pressed the starter button and everything went off (cluster lights, headlights, clock, and no starter action). I released the start button and everything stayed off except the clock. I disconnected the negative battery terminal and I believe I heard a relay release. Then I reconnected the negative battery cable and turned on ignition key again. The cluster and headlight came on. I pressed the starter button and the starter engaged and I believe the engine would have started if I had allowed it to start. Everything looked normal.
I had this or a similar issue once last week and it appeared I had a bad battery. I tried to jump it off and it would not turn the starter. I left the bike at home and drove the car. I came home from work many hours later and tried again. The engine cranked as it is supposed to crank. Any ideas? It seems like it might be a relay issue. Has anyone experienced this behavior?
