What meter? Dash meter often lie. Use a real meter and check alt output etc.
Check volt often lies too.
Volts can be fine but alt at engine idle make low amps. Problem is amps drawn by car from alt is to high for most meters to read. most read 10 amps max. amp shut can blow it's fuse. unfuse shut can fry.
Carefully Read "Watt Story." (I'll add charts to cave later.)
measure alt and crank pulleys. crank/alt = y, y x engine RPM = alt RPM
Look at 2000 RPM vs output amps. Is close to pulley ratio (Most are 2
.5:1 - 2
.6:1) at 900 engine RPM
weak wire anywhere just adds to low power...
Power chart of 12SI alternator
CS alt reach peak power sooner than 12SI but a never found cs130 chart. cs130d is close...
