Question -
Chris, I just purchased an 82 Yamaha XJ650 Maxim  that had not been ridden for 2 years. This bike is equipped with a safety side stand switch that will not allow it to start until the side stand is up. My buddy disconnected it because the switch was broke. The headlight does not work now, and he had not checked to see if the light had been working prior to disconnecting the switch for the side stand.
He recently moved so is not available to recheck the bike, and so I need to know if these two items are tied together, or do I most likely have a headlight problem. Fuse is ok, and the bike runs great.  All other lights are fine.
Answer -
Hi Norm.

First thing to do is to get the repair manual.  It will show you what wires to check for shorts.

The headlight is normally on a seperate circuit from other lights so check for it and be aware that the headlight is a completely different circuit from the sidestand cutoff relay.  They are not connected to each other.

Check the headlight bulb and fuse with a multimeter to be certain that they, and not something else, are not the culprits.

Let me know what you find.
Good luck and ride safe.

Falcon,  I found my problem.  Again, to me this is a new bike...It appears the headlight does not come on by just turning on the key. The starter switch must be pushed to attempt to start the engine,  and then the headlight comes on. This design was built in so if the key was left on, it would save the battery.  I proably should have spent a bit more time to track this down, but it did seem to bring a question into my mind on the competence of the Yamaha Dealer Mechanic who was trying to inspect my motorcycle!
  Thank you for your help, and Safe riding to you.

Answer
Hi Norm.

That can be confusing since some model/year bikes from each manufacturer does that and some do not.  I had the impression that the light wasn't coming on at all, even with the bike running, so I am glad that it was nothing to be concerned over.

Have fun with the new bike.
Ride safe.
