In the last week or so, random problems that I believe to be electrical have popped up, including the failing of the odometer and speedometer. Yesterday, After driving around 30 miles or so, I parked for an hour and a half and it would not start again, instead I could hear what I believe is the flywheel clicking, but the engine would not crank. I tested the battery voltage last week and it seemed fine. If anyone has a wiring diagram for this vehicle, I would really appreciate you sharing it with me, as I am currently at a loss and need my car for work.

Good afternoon,

First, I would load test the battery and make sure it has 12.6 volts. Without that, the starter will not work.

Roy, thanks for getting back to me so quickly. While my multimeter it attached to the battery terminals, I am right around 12V, not exactly 12.6, but when I turn the ignition, I am getting no draw from the starter. May try to drop a new battery in just to test it, but I do believe it is simply time for a new vehicle, it's been a long time coming. I appreciate your help, and this website is awesome.
