Red alternator light came on, my plan, missing anything?
My red alternator light (already converted from generator when I got the car) came on bright red suddenly today while driving. I did notice that it seemed to dim slightly when pulling away from stops but I didn't have much time to observe being close to home I just put her in the garage.
I plan to do these things first:
* Check that V-belt is tight.
* Test battery.
* Check Alternator connectors and battery leads.
* Test alternator.
So now I have a few questions;
Is there anything I left out you guys would check?
Can I check the alternator in place or does it need to be removed?
I doubt it's a connector issue since the intensity of the light seems to change which makes me think Alt is going out, battery is bad, or maybe the belt. Would the fact that it came on super bright immediately point to anything specific over another cause?
If it's the alternator, which is correct model or type for the M127 if I go with Bosch? I read somewhere else that the car may have come with a 35 amp but 55 amp is common replacement, is that correct? (I may buy new or factory rebuilt unit.)
