[mrexp21]

Using which device or method, I could calculate and determine total electrical loads and amps used in a vehicle ?

EDIT: Partly misinterpreted question, so deleted my response.

Volts * amps = watts
Add up the wattage of each component.
Divide total by 12 (or 14) to get load on electrical system.

Or hook up an ammeter to your alternator.

Or hook up an ammeter to your alternator.

just as long as you know the peak is less than your ammeter's fuse is flowing or use a dc clamp meter

That's what I originally said.
But I also partly misunderstood the question, so I decided to retract my comment.

I get very suspicious when they have a post count of 1, and it sounds just like a teacher question, with NO explanation as to WHY they want the answer.

This is an excellent link. Thanks and hopefully I don't have ever need to use it.

I agree it is an excellent link.

But a better way, is to use a current clamp meter (if you have one, can borrow one, or afford one, they are NOT very cheap, but not that expensive either).
A clamp meter means you don't need to disconnect the wiring.
