[T3] Head lamps on left or right a idle , turn signals lash fast.

[Jim Adney]

Not sure what your problem is, or what you're asking. I suggest you re-read 
and correct your typos before sending. 

Are you complaining that your turn signals go too fast at idle? Yes, that can 
be a problem at times, due to low voltage. Usually, a good battery will hold 
the voltage up for a few minutes while idling, but only after the charging 
system has had enough time at speed to bring the battery up to full charge.

Right after starting the car, the battery will always be somewhat depleted, so 
it will need some recharging. This won't happen at idle; the generator needs 
to be brought up to a medium speed for a minute or so to recharge the 
battery.

You can test this by watching the voltage at the fuse box to see how high it 
needs to be for the turn signals to work correctly. Do this by bringing the 
RPMs up slowly while watching the voltage and the turn signals. Once you 
know the threshold voltage, let the generator recharge the battery by driving, 
and then watch the voltage decline when you come back to idle. 

What is that voltage threshold for your car, and how quickly does the system 
fall back to that voltage after you drop back to idle?
