Remove the side cover so you can get to the battery terminals. Check voltage at the battery terminals with the key off, it should e 12.4-12.6 volts. If less than 12.4, your battery may be failing.

Start the bike and check the voltage again. With the bike running, it should be 13-14 volts. You might have less voltage than this when idling. If you increase the RPMs a little, it should come up to 13-14 volts. Mine would have have 13.4 volts even at idle with my heated vest on.

If your readings are less with the bike running, there is a problem somewhere. It could be anything from a bad stator to a loose or corroded connection.

Faulty grounds/loose and corroded connections are a fairly common problem, especially on a bike that's been stored outside or exposed to other wet conditions.

Your headlight dimming when the flashers are used could very well be a faulty ground in the lighting circuit. Finding faulty grounds and loose/corroded connections can be a very difficult thing to do.

Good luck.
Thank you. I have seen some wires that look as if electrical tape has been used for some reason or another....i am the third owner. I shall do some investigating, hopefully it wont be to painful.
