[QUOTE="knukonceptz, post: 2176850, member: 548221"] You must have some dead *** batteries then, with the car on and nothing else at 2k rpm (or any RPM) you would get ONLY what the car needs to operate (probablu less then 30A if nothing is on) The loads used on a Test bench at a good shop are gradual, they can vary the load like you can in real life in your car. The cheapy testers, like Dom states in his post, are instant full load and that can cause problems with your regulator. Fact - on your car, the alternator will only output the load it is required to put forth. If it put out a constant 200A you would cook your batteries. I am sure you could have this arranged ,some how eleiminate the regulator (funny - the NAME implies what it does, regulates) A clamp meter is all you need, as suggested, put it on the positive wire from the alt to battery and you can see in real time what you have to work with. You can also put it on your amp power wire. I think some might be dissapointed in the number of amps they are really drawing....... [/QUOTE]
