The RED Batt light has been coming on and going off lately. When I put the key in and turn it once ALL the Lights come on fine. When I start it they all operate normally. After A while the "Battery " Light comes on then will go off then come back on. I did the wiggle test to see if there is a break at the ALT. It does not flicker it is steady. I also took off the Battery cable while running and NO Battery light will come on. I also disconnected the 2 wire plug on top to see if the light would come on and it doesn't. The only thing I did not do was try it while the light was on to see what condition it would or would not show, Light on or off.
Wondering if its the ALT going or battery, Or a Short.The battery is a year old Alt OEM 1990 .This is a Super Coupe 1990

I did put a Volt meter on it at the battery terminals and got a 14 VOLT reading at the MALE connector of the ALT. I got 14.9 VOLTS IS this too high?
Thanks Agin

Alternator

It most definitly sounds like your alternator is overcharging your battery. The voltage regulator is prolly shot, and it is internal to the alternator. Get ready to spend like $130 to replace your alternator, as the SC uses a 95 amp alternator. If the battery was letting go, you would have to jump start your car, bacuase it wouldn't hold a charge.
