Am i pulling too much curent?
Hi, i have a VW Urban Fox '06, i do not rightly know what the alternator is capable of, i have two amps in the car, a 150watt rms and 300watt rms, no caps.
When the engine is off, the battery is at 12.5v, at idle it is 14.3ish v and when it is idling with the music as loud as i will ever play it(otherwise it is uncomfortable) the potential across battery+ and the chassis usually stays within 14.1-14.4v with the lowest it ever momentarily dropping to around 13.9v, am i pulling too much current from the system?
I have also ordered some parts to assemble my car pc, consisting of a netbook that usually has a 90w charger(no battery installed, i think it will pull less current that way?)
I am also going to buy a 7" lilliput.
I know it is a small car but can anyone tell me what the signs are that i am drawing too much current or if i need a new alternator?
