B16031C P0A1A ALTERNATOR

[508c5]

Hello,

I got these codes. No service or battery light appears on dash and charging seems to go on REGULARLY.

I must note that while dismantling the catalytic converter sparks flew from the alternator (i forgot to disconnect the battery).

Also, the connector in the picture seems strange (no one messed with it) - only one string is attached but the other doesn't seem torn but intentionally disconnected (no exposed string).

How should I treat this ? CONFUSED.

vin number VF3**************[VIN obfuscated, can be read by forum staff]

thanks

I think that the connector in the picture looks correct, just the way they make them for some reason.
Check that you have +12V on the big alternator terminal.
There is also a fuse in the box behind the glove box which supplies power to the charging control, (don't know the fuse number on a C5), it would be worth checking.
