how much effect will an underdrive pulley have on battery charging?
Reason I ask is there is one on the car....never reads over 12.7-13.2 on the DIC and the car sounds weak when you crank it sometimes. Charging system checks out OK. Battery is just 2 years old...36 mo battery. I know you never get 36 mos but this has been doing this for awhile now. No excessive stereo etc in the car.
Oh yeah if you hook it to a trickle charger it charges for a bit then the charger says TROUBLE.....so am I looking at a battery issue?
I suggest you take it to an auto parts store. They will pull a check on the battery and alternator for nothing for you. That way there is no guessing or fooling around wasting time on what ifs. I have an under drive pulley and have never had an undercharging problem.
Had mine installed for about 2 weeks now and the voltage is still the same as it was prior. I wrote down where all the guages were prior to the install to verify nothing was messed up.

Battery is going south. Get at 72 month battery next time.
