Default 1993 Dodge Caravan Check Engine Codes

On my way to work this evening, my Check Engine light comes on, it's a 93 Caravan with a 3.0L V6 engine and 190,000 miles on it.
So I get to work, flip the key on and off 3 times, and get codes 12 & 41, figuring I could look them up online when I got home. Well, would you believe that it's pretty near to impossible to find a list of check engine codes on google?!

Could anyone give any help as to what this is?

Default RE: 1993 Dodge Caravan Check Engine Codes

This is from the Haynes Repair Manual for Caravans, Voyagers, and T&C 1984-1995:

Code 12- Circuit: Number of key-ons since last fault or since faults were erased.
Code 12- Description of fault condition: Direct battery input to controller disconnected within last 50 to 100 ignition key-ons.

Code 41- Circuit: Alternator field not switching properly.
Code 41- Description of fault condition: An open or shorted condition detected in the alternator field control circuit.

Good luck.
