12 volt constant at ignition gone

Hi

My car did not start when I turned the key to the start position,not even a crank over, so I checked the 12 volt constant and it had no power,so I found another hot source and tapped into the harness wire and it starts, but I need to know why my 12 volt source quit in my harness, All fuses are OK as far as I have tested.

I need to know if using that other hot source will cause any further problems, should I put a fuse between the hot source and where I tapped my harness?

I have a Chrysler 300C 07 model, the color of the 12 volt constant is light blue/red, would be nice to know where that wire goes to or what fuse controls it if there is one

Fuse box or circuit breaker at battery? Both in trunk. Don't worry your car will be called a Lancia next year so take it to a dealer and they will say Fix It Again Tony.

No, it's not safe to jump power like that. You need to find out what failed, and why. Most likely you have a blown fuse somewhere and by simply jumping power most likely you will just blow it again and possibly damage more because you are using a different circuit to provide power.Kevin Pierson

Thanks but I have checked all the fuses acording to the fuse location manual, can anyone give a hint where to look?

OK,now I'm effing invisible! Re-read my post again dummy it tells you where to look AND test each fuse with a DMM, looks can be deceiving. If you can't find it; for safety sake, run a thick lead at least 3mm from the rear battery and fuse it at the battery with a 50 amp fuse.

Oh and another thing, if you have to take that last route, don't just join to the original lead, cut the original then join them.

Thanks but don't call me a dummy! I know about the fuse box, I checked each one with a Volt meter front and rear, but I do appreciate the reply:). Do not take this wrong but I think what you are saying is cut the original lightblue/red from the harness and use the wire I tap in directly to the lightblue/red wire that is left still attached to the key connection that plugs into the key cylinder

Have any modifications been made to the car? Anything change on the car right before it lost power?Kevin Pierson

Yes but my original point was don't check with a voltmeter, use continuity.

Hi

Yes an attempt was made to add a touch start, I touched the start button and thats when things went wrong
