Hello all,
New here because I just bought a 98 Pymouth Grand voyager (please excuse me if this is the wrong place to post). When I got it, it did not have a battery. Threw in a new one and gave it a go, it was pretty much comletely dead when I got it home. Wouldnt even start once I turned her off. The batt has been on charge for a few and I drove it much further and the thing didnt die. Got back home and it started right up after I turned it off.
Now I dont have a way to test the battery, but it does seem like its still charged. But assuming its not, is it possile that the codes could be thrown on a weak charge? Im wondering this as other Dodge vehicles Ive had and still have will throw random codes on a weak batt. That and the van seems to shift quite well. Looking for some direction. Any help would be greatly appreciated. TIA

Early update: Took a multimeter and I had 12.88v with engine off. Ran it in the driveway at idle had slightly lower voltage. Reved it up and would increase voltage ~.15 or so, but only when reved. Sat in the AC a bit and tested again while running, AC and lights on voltage was 11.88 and dropping.

Also, I noticed I couldnt get the Max AC button to work nor recycle air. I did do the AC reset thing because all the lights were blinking. No flashing lights (other than the rear wiper buttons), but now no lights at all ....
