Check the wiring harness above the passenger side front axle.
In the G1's 2000-2005 the hold down clip tends to break causing the harness to drop & rub on the axle...this will cause wires to burn through & break.

Most of the time this happens on the 2001 & 2002 PT Cruisers.

The Crankshaft Position Sensor was easy to replace on the 01-03 models as it was right above the oil filter. In 2004 they moved it to behind/under the starter motor. As a result the wire harness was changed.

The kind of digital meter needed to detect a drain like this is not the multi-meter most folks have at home. It's a more complex device that has a third lead with a "current clamp".

In the past you could just unhook the battery cable and measure amperage between the battery post and battery cable. But on modern vehicles, the electrical system may not function as it normally does unless a fully charged battery is installed and fully connected. And of course, modern cars also have a normal amount of power drain anyway.

To measure the amount of parasitic drain, you need one of these fancy meters or you can just got to a parts store like Advance Auto and let them test the parasitic drain with their tester.

A simple Digital volt ohm meter would have worked just nicely

I considered who the member was and what level of experience may be there with the suggestion.

If the PT Cruiser has a major short draining the battery the link below will help you find the short by pulling one fuse out at a time but first we need to find out if the generator is charging.

If you are not positive the battery is good the link below might help determine if the battery is good or not.
