how many amps should this pull? everything else I can calculate but have found nothing on the field coil.

Standard Ohms Law formulae tells us that V (volts) = I (amps) x R (Resistance). Since we know the voltage is 12v and resistance is 3.5ohms, our transposed formula would be V divided by R, (12 divided by 3.5) leaving us with an answer of 3.4286 amps.
Here enduth the lesson for today..

That will get you in the ballpark....
Voltage is varied to this by the regulator, as that's what controls the alternator output. Plus you have the effect of impedence, not just resistance. So if you're looking for a specific number you won't get one, there's too many variables...Fast, Cheap, Reliable... Pick any two

Didnt know if he was 'electrically minded' enough to get that deep into it for him. Figured he was just trying to get a picture of overall system load, and the ball park would be close enough.
