does your RPMS drop when your idling?

[QUOTE="drkodin, post: 844370, member: 545032"] i would like to know why you think this, because it just doesn't make any sense, more batteries would drastically help in his situation. however there is a drawback that most people misunderstand as something that needs to be avoided at all costs. A battery is a backbone to any electrical system, it works in conjunction with any electrical system and is fully designed to run on its own accord. Running a system off a battery alone or by relying on that battery to keep up the charge while the input voltage is low is by no means a bad thing. The part that most people go the wrong way is they tell people that they will only end up killing an electrical system too soon by using multiple batteries off a stock alternator. If he is at idle, and he adds a second yellow top to his system, all his problems will go away including the possibility of problems like headlight dimming as long as he doesn't discharge more than he will EVENTUALLY charge. The alt will pick up the moment the car starts moving again and since music is dynamic it should also have more than enough current to start charging the batteries back up slowly. ok, with that said i don't think that a second battery is necessarily the best solution to the problem. The best solution actually derives from my point on multiple batteries (proving that single or multiple the issue remeins the same) that he isn't allowing time for the battery to charge back. For a single yellow top on a 110a alt i would give at least 5min driving time load free (no music, heater, AC, winshield wipers, power windows, etc) to charge back up. 2 yellow tops i would want 10min driving time. This insures the charge is there not only to start the car but also to save your alternator. The only thing that will kill an alt faster is if you drain the battery so far that the alt is the sole source of current. [/QUOTE]
