Hey guys back again, so my 06 DTS seems to have a power draw in it somewhere. When I first got the car if I didn’t start it up every 4-5 days the battery would completely die. I have had to get my battery recharged 4 or 5 times now because of this problem. I drove the car for almost a month and a half straight no issues beside my AC drain tubes plugging up but the other day I drove it brought it home parked it in the garage like normal and when I came out to take it to work the next morning it was completely dead. When I opened the door to get in, the driver side and passenger door were making electrical clicking noises and when I went to turn the car over it had no power what so ever. I tried charging the battery myself but my charger told me it had an internal cell shortage and wouldn’t charge it so I took it to my local battery place and they said it charged up and is holding a charge perfectly fine. I checked my alternator a while back and it was still cranking 14 amps. I’ve also pulled all my fuses none were broken and used a test light to make sure the ports were good. I’m kind of at a loss right now on what could be causing this. Does anybody know of any specific things that may be giving me this issue?

BEWARE OF SCAMMERS. Anyone trying to get your money should be checked out BEFORE you send anything anywhere.

you tube parasitic battery drain using a meter, be Sure to close all doors, no key fob nearby and trip the hood latch so the car thinks its closed, it takes a good 30 minutes for the car to go asleep...... go visit uncle Jeff's site and order a 1.5 to 2.0 amp battery tender trickle charger
Like said anytime you're not driving the car for days at a time get a trickle charger. The battery will last a lot longer and you won't come out to a dead battery.
How old is the battery? If it is 4 or 5 years old, assuming it is OEM spec, it is probably sulfated. It might check good but it will have no reserve and low crank amps. Don’t waste time analyzing an old battery. Replace it with a quality OEM spec unit.
I'm no expert and far from a mechanic but did the light flash when you hooked it up that way?
I never seen it done his way but I was told to start pulling fuses one at a time until you find the one that makes it stop flashing. Remember, most modern cars do have a slight trickle or how would it respond to the remote?

Sorry I wasn’t able to respond on here I somehow was banned for spamming? Lol not sure why. Tripwire I am wondering if mine is having the same issue with the diode someone else had recently mentioned that to me and that’s one part I have not replaced yet. Soapm I honestly don’t know I’d have to look at the fuse diagram again and this suck has wiring everywhere first Cadillac I’ve had so it’s definitely taking me time to figure things out with it. Piper Tex have had the battery for just little over a year and have had it tested at my local battery shop where they said it’s got a lot of juice in it and is good to go as for specific battery I have it’s a Deka CCA @0 degrees says 840
