I have recently bought a 1986 Yamaha Fz600s and been having fun riding. I have put on about 3.5k miles when the other day I was merging onto the interstate at I went to put the left turn signal on and the engine dropped in RPM as the signal flashed. At first i thought it could just be a short and i would look at the switch the next day. I parked the bike and as a thought tried to start it again. When i tried to start it a gain all i got was a click like there was not enough charge in the battery to turn the bike over, but all the lights and headdlights and turn signals worked just fine. The next day I tried to start it again and it would turn over only a couple of turns then just click. When i would mess around with the run off switch it would turn and it got it to start. Took it around the block in first gear then shifted to second couldnt get it to over maybe 6k RPMs. sounded like crap then i shut it off. Started to get into it more today checked some harnesses and wiresi did have a loose connection in the run/off switch red wire, It was corroded. My question is could this be a problem caused only by the starter solenoid or the solenoid and another issue together?

This belongs in the garage section....

Anyways, a corroded connection will mean that you're not pulling enough charge across the battery in order to correctly engage the ignition system. Which is to say you aren't getting enough voltage off it to get a spark.

The smartest thing you can possibly do right now is to not turn the bike on again until you get that fixed up.

Because you aren't pulling enough voltage the reg/rec will try to increase the voltage sent to the battery which may potentially burn out the stator (coils of wire in the alternator). That's an EXPENSIVE fix.

So, clean up the connection, charge the battery, and try again.
