current consumption
Hi all
Can any one tell me what the total current consumption is for a 7 type car, excluding the starter motor.
The reason for the question is i have to replace my altenator so i would like to get one, which is as small and light as possable.
Thanks

you only really need the constant average, as stuff like horns etc arent on. Id work out the headlight draw, depends on your bulbs, maybe around 250w
or 20amps if you are driving on full beam, and then add on the coil and a bit for good measure. Bear in mind that an altenator doesnt really weigh
much in the scheme of things, compared to the ball ache of having to jump start a poorly battery. I myself would go for a medium battery and a normal
altenator, cos i cant be arsed changing it.
Is the standard sierra one 70 amps? i wouldnt want to go below 50 amps really since the battery does need a good charge if its not used regularly.
All IMHO ofcourse

Joel - IIRC the dip beam needs to switch OFF when main beam is working (except flash!) so this makes 120W max. (+30% = 15A)
