[6pack] alternator 72 TR6

[Bob]

Hello,

Just started up my 72 idle since May. Started fine but the ignition 
light flickered after a few minutes and then the ammeter was alternating 
from about 3+ amps to 3- amps along with the flicker. Turned on the head 
lights and no flicker. Drove down to get gas and flicker continued 
unless I put on the brakes.

Just put it in the garage and after starting, the normal +10 or so on 
the ammeter then normal.

Is it time for a new alternator or is rebuildable? Delco I believe.

Thanks,

Bob+
