Alternator Causing Parasitic Drain

Have you performed a parasitic drain test with every possible fuse removed yet still get a high amperage draw? Check the alternator! It has a direct feed and depends on a series of diodes to keep voltage from draining from the battery when the car is off.

There are a total of 11 diodes inside of this particular alternator. This is a great case study of a bad diode rectifier. Here is a link to a diagram for this particular alternator. It's a 1994 Mazda MX-6 2.5L KL with a stock 90 amp alternator. http://www.pmx626.info/US/Mazda%20626%20&%20MX-6/Work%20Shop%20Manuals/Scans/1994%20WSM/G-07.jpg
