Wiring in a larger alternator

[Orange Crate]

There are a couple of really easy checks you can do, called out in the factory service manual (available free on this forum) One is using the grounding tab provided in the back of the 10-SI to eliminate the voltage regulator after you have your test meter hooked up correctly. The diode check is called out in the manual with nice pretty little pictures too. It shows you exactly where to put the leads of the meter.
