Hi there! I have a head scratcher here. I went and got an oil change on my '05 SRT-6. Started heading home, then got a beep and oil level "HI" on the center gauge. Called the shop, they immediately took it in to see what was going on, said everything checked out but now I have a battery charge error light on. This is particularly interesting because the light was NOT on before they double checked the oil levels. Drove back home about 30 minutes and thankfully the car didn't die on me but I still have the light. Irritatingly, the oil level HI notice came back on and subsequently went away. ARGH.

So my question is that since these are seemingly unrelated issues (poor timing of coincidence?) is there anything I should double check connection wise before tearing into this and pulling the alternator and getting a new one installed? I have no problem doing it myself, it's just more of an inconvenience, if you know what I mean.

WHAT I'VE DONE:
I double checked the cables and tested the voltage at the battery terminals. Battery when I got home was low. About 12.05V and after "topping it off" and letting it sit for a couple days, it registered 12.68V and she started right up. Running the car it did dip to 12.29-12.3V at idle and then applying the throttle brought it to 12.5X Volts. So there is SOME charging that is seeming to happen definitely but not much.

WHAT I'VE NOT DONE:
I have not checked the voltage at the alternator. Seems like bit of pain to get to the wires on the back to check voltage. Any tips?

Thanks so much for your help in advance! I've had my SRT for 7 years and it's been reliable except for the RCM which was replaced with a rebuilt unit in June 2020. On an unrelated note, I also checked the oil levels and things seem to check out. Any chance the low voltage from alternator is making other things go crazy?
