Ignition issue? I am not sure... PLS HELP

[nelly27281]

So on Friday, after coming from office when I shut off my H3 (06):
- Parking gear indicator light stayed on.
- When I removed the key, light stayed on.
- When opened the door, chime started as I left my keys in.
- Next day morning, battery died.

I googled a lot but everything is re-directing me to ignition switch replacement.

So question to all gurus, what is the reason behind this?

As always thank a lot in advance.

UPDATE:
Here is the pic for the same.

replace the battery, you get all sorts of funny codes when the battery goes dead.

replace the battery

I have swapped my battery last year only.
Silly question but I don't how it may because of battery.

How are your battery terminals? Are you still sporting the original ones? Most upgrade terminals to sort out electrical gremlins first.

Well those are original n still good (I guesss).
Can it be ignition switch?

Those symptoms are very common when there's a bad terminal connection or the battery is weak. Check the easy stuff first; tight, clean connection and full charge. The OEM battery connectors that GM used are junk with minimal contact area. If the connection is poor, the battery won't fully charge.

I know it doesn't make sense but, trust us. Many, many weird things happen to the H3 when the ground is bad or the voltage is low. Its the cheapest (free) and easiest thing to check. Lots of us on this forum have replaced the factory cables due to these goofy electrical gremlins.

I owe you guys big time.
Battery terminals are the culprit. I am planning to change both the terminals along with the wires.
Any suggestions on that..?

Military style terminal clamps are my preferred style. Easy to add accessories later.

Quick questions:

So you guys have used old/original wires and connected them to new terminals or are you using new wires?

Will it be too much work if I'll change the wires too (as I don't know how to do that) ?

Cast zinc terminals usually solve the problem but if you want to take it up a notch, replace the smallish cables too. A lot of people also go up a battery size and ditch the battery box. Sometimes the main connector under the fuse block is problematic too. GM really cheaped out on these components causing one of the most common issues with H3s.

I just cut the old terminals off and replaced them with new zinc terminals. I used the original cables because they showed no sign of being bad.
