I have a problem with charging and I'm not sure if it's a rectifier problem. So I posted here asking for help.
I tested alternator, they all measure <0.1 Ohm between the pins, and no short to ground. So not a problem with alternator.
I run the engine without rectifier connected to alternator. The alternator read 15.3V AC between pins.
The problem starts when I connect the alternator to rectifier. The voltage from alternator drops to 3.3VAC. the voltage output from rectifier is also 3.3 VDC.
What confused me is when I pulled out the rectifier. Forward bias all show 0.467V as it should be, and reverse is Open Loop (also good). All the test I followed were from here:
