bright\dim, bright\dim

When I use my blinkers the dash light go bright\dim out of sync but in time with the blinker indicator on the dash, What gives?

Does it do this at crising speed or just at a stop?

 

It is fairly common to see this when stopped and the engine at idle.

When idling, the Stator is at a very low output level and so when the turn signals illuminate the extra draw on the electrical system is causing a slight voltage drop in the charging system. That is why the rest of the lights go dim. This is nothing to worry about.

 

Now if this is happening whil the engin is at cruising speed, then it may be the beginings of an electrical problem on the bike. This could be anything from a dirty / corroded connection to a stator or Regulator/Rectifier (RR) that is on the way out.

You don't have the year of your bike in your header So I will answer on how my 89 1st Gen was doing that until I disconnected the electric to the front forks that engaged while braking, and sucked a lot of electric current.

I have an 83.5 XVZ12DKC2; that M/N is found in the 84 catalog. I have no electric brakes, I have some LEDs on the fork, that's it. The pulsing is at any RPM so I will be looking for that needle in a haystack (bad connection) and hopefully I won't have to pull the rotor off the 85 parts bike I have. I saw a post about how to check the rotor's output a while back...

I found the cause for the bright/dim issue! I had some funky wiring connections behind the head light, how I did that is beyond me! I got it sorted out now THANKS!
