Check your battery terminals and make sure they are good and free of corrosion. If they're OK, check the positive cable connection at the starter........could be loose or possibly shorting somewhere on it's way to the starter.

Check your wires for a pinch or missing grounds.
p.s. using some capital letters and periods would make your post much easier to read.

flicker

Hi,
I just rebuilt my alternator, and it had the identical problem!
Replaced the Rectifier(diode assembly), diode trio(sort of a bridge) and brushes. Now, it puts out the original 120 amps, no headlamp flicker. It cost about $40, plus time. What do you think?
