Check out the diagrams (below). Please let us know what happens.

Is it possible its the alternator? And also, upon changing battery, all gauges are inactive as well as digital odometer, plus power windows and radio wont work unless key is in the acc position.when car is running many of the accessories are unavailable.

The alternator will not cause these accessories to stop working how are the fuses?

All the fuses were seemingly fine, upon recharging up the battery, all those earlier mentioned accessories suddenly worked again, multimeter reads around 12.7 on battery without engine running and jumps to 14.2 ish with it running so alternator seems to be doing its job, is ignition switch a possibility? I thought i remember hearing something about a recall on the intrigue on the ignition switch

Yes, the ignition switch can cause this issue. here is how to replace it. Check out the diagrams (below). Please let us know what happens.
