I would prefer a larger alternator so that I have higher voltage at idle, my afterglow stays on for 3 mins and the voltage barely gets over 12 even with the rpms up. Thats a lot of strain on the battery. It gets worse if I need the defroster blower and rear window defrost. I am going to scour the yards near here Saturday morning for a Saab 115A...that'd be perfect. And I could put in some new wiring/terminal block. Mine is old and in bad/corroded shape. (I do have a new one though...had to come from Germany!

)

In the winter you do a lot of idling through traffic when its snowing....with all defrost on....headlights...fogs....stereo.....wipers....the power draw is very large.

I'll see what I can find this weekend...
