Default Codes from my 92 xj

MY CHECK ENGINE LIGHT CAME ON SO I WANT TO KNOW WHAT THIS CODE MEANS, I TURNED THE IGNITION OFF ON OFF ON OFF ON THEN WAITED FOR THE CHECK ENGINE LIGHT TO START FLASHING. THE CODE WENT 1 QUICK FLASH SHORT PAUSE FLASHED TWICE THEN LONG PAUSE THEN FLASHED 4 TIMES THEN SHORT PAUSE THEN FLASHED ONCE THEN LONG PAUSE THEN 5 FLASHES SHORT PAUSE THE 5 FLASHES AGAIN. I THINK TO READ THE CODE AS 12 41 55, BUT I AM UNSURE IF ANYONE CAN HELP ME OUT THAT WOULD BE AWESOME.

ALSO MY VOLT GAUGE ON THE DASH GOES FROM 14 -9 THEN BACK UP OR SOME DAYS IT WILL SIT AT ABOUT 9-10, THEN SOME DAYS IT WILL BE FINE AT 14. I HAD MY WORK TEST MY ALTERNATOR AND IT SAYS ITS CHARGING AT 13.9-14.1 SO ITS GOOD JUST DONT KNOW IF THAT IS WHATS TRIGGURING MY CHECK ENGINE OF ITS SOMETHING ELSE IS WORNG. THE XJ ALSO HAS 225K ON IT SO HELP ME OUT PLEAS


P.S. SORRY FOR THE CAPS MY WORK KEYBOARD ONLY LIKES CAPS LOL.

Code 12-Memory to controller has been cleared within 50-l00 engine starts.
Code 41-Charging system circuit-output driver stage for generator field does not respond properly to the voltage regulator control signal.
Code 55-End of message.

Full list @ Jeep Cherokee Trouble Codes for future reference.

Id say your alternator issues are indeed the reason the CEL is on. Don't know much about troubleshooting other'n if it quits I probably need to pressure wash the mud out of it, lol.

I may be wrong but the voltage regulator on Cherokees as well as many other chrysler products is the PCM..... so basically you just have a bad alternator.... probably a bad connection inside or short brushes...
