[QUOTE="jrwalte, post: 5192711, member: 584454"] Having the low voltage at idle is due to the HO alt not spinning fast enough to start the electrical field and it's giving absolutely no output. You may have a smaller pulley, but not small enough. The low bat voltage is probably due to idling too often with a load from the stereo and not enough time inbetween to give the battery a good charge. What RMS are you running? 1 battery may not be enough, either. Having an HO alt does not prevent one from requiring a second battery. It does just about nothing, actually. [/QUOTE]
