As mentioned in the subject, I have a 1996 rodeo and here is the problem I'm having:
I purchased an amplifier, stereo and speakers to redo the stock sound system. Everything pretty much works fine except when I do a sudden acceleration of the vehicle. When I do this, the voltage meter drops to around 12V and the amplifier drops the volume of the music(music also becomes distorted temporarily). I have had all the wiring inspected several times over with no problems found. I installed a capacitor with no luck. I replaced the battery with no change in the problem. I had the alternator tested and it passed with flying colors. The only thing I've come across that seems to be related is the behavior of the alternator during sudden acceleration. There is apparently a feature in the rodeo where the computer? drops the voltage output of the alternator during acceleration to reduce load on the system. From what I could find out about this feature, the voltage is not supposed to drop below ~12.8V. My guess is that maybe after all the wear (120,000 miles), the drop is no longer at 12.8V but might be lower. I have no idea how to fix that if that is the problem. Any suggestions would be appreciated.
