Question about 2002 Chrysler 300M
Tried to start the car one day, just clicked. Changed the starter wasn't it. Tried to jump it, voilent spark on positive post. I seperated the two cables on the positive post, both of them spark when I touch the battery cable to them. Trouble shot them with trouble light. Trouble light went out when stop lamp and park & horn fuses are pulled. As for the second cable, that I guess goes to the fuse box on the side of the dash, found the int/bat fuse blown. I replaced it but still not getting any power inside of the car. No interior lights, nothing.
Do you know how to use a DVOM - digital volt ohm meter to trouble shoot automotive electrical circuits ? Using a wiring diagram to find testing points in the B+ power flow of the vehicle electrical circuits .

. stop lamp & park/horn circuits grounded on load side. What can cause this? A direct short to ground .

remove pos batt cable 1st
I would start examining the door switches since they are a constantly cycling part, Im not exactly sure how many accessories run off the door switches but I would examine the drivers door switch, study how the switch removes from the door, gently pull switch assembly out, being careful not to yank wires loose. remove it and look for arcing marks or soot, try all the doors, then I would disassemble the dome light itself if you cant find it, if you find the short you should reinsulate with thermoheat wrap heated with a hairdryer and maybe even some extra electric tape.

Clicking??? Probably starter/alternator. does the starter turn? The clicking, is that all you get when you turn the key? Have the battery checked and make sure its holding a charge. If battery holds a charge, its time to have your alternator tested, if the alternator checks, then the clicking may be the starter/soleniod. Places like autozone will check the battery/alt for free, provided you can still drive to get there.

The interior lights are controlled by a module that gets its information from the sensors in the car door and the switch on the dash that is associated with the dash lights. There is an intermittent short in one of the doors or the module.
Sorry it has to be so vague, but there is not way to know where with out taking some things apart. An intermittent electrical short that can not be duplicated on demand is the hardest thing to diagnose. This is one that needs to go to someone who specializes in electrical diagnosis.
Hope this helps
