voltage problem
my '86 944's voltage tends to get lower as it warms up. most of the time, i'll start up and it will stay perfectly horizontal (on the gauge) at 13 volts. then it eventually decreases. it will move to 12.5 next, then it will stay at 12.
is this normal? i dont think it is, but i could be wrong, obviously. i can definitely feel a loss of power between the times when i'll floor it at 13v and then at 12v, or even 12.5.
is this a problem with the voltage regulator? is the regulator external or easy to change on this age 944? could the battery just be old? its a recent purchase, so i'm still chasing small problems around the car, especially wiring ones. i'm thinking this could be part of the reason some of the electrics dont work.
