[QUOTE="helotaxi, post: 449485, member: 550915"] He usually is correct in his conclusions, but his "proof" never stands up to scrutiny when applying scientific method. He decides what the test should show to make his point and then designs the test to show what he wants. Look at the famous "cap test," for example. He puts a cap (given it was 15 farad which is pretty large) on a 2kW system that was running off a measly 80A alt, cranked it to hell and back and said that since it didn't keep the voltage at a higher level that caps were worthless. That test prooves that caps can't make current, but anyone with half a clue about electricity knows that already. The alt never had a chance in his test. Throw a 200A alt on there and try again. I think the results would be quite different. The voltage would be much more constant than without the cap. A cap won't fix an electrical system that is wholly outclassed, but it will make an already adequate electrical system better and it may help a marginal charging system keep up with the occasional transient where it would otherwise struggle. He has claimed that a chassis ground is always better than a 1/0 wire running back to the battery. On some cars this might be true. On the vast majority of newer unibodies there is no way in hell. Manville Smith of JL has called him out on this and he refuses to take the "Pepsi Challenge" so to speak. He and David Navone had another "demo" that was supposed to show that adding a second battery to your system was going to hurt the charging system. This involved a person on a bicycle pedaling to turn an alternator that was charging a battery powering some light bulbs.
