Dealership killed my battery

[DARTHSHO]

as the title says the dealership killed my battery I blew the head gasket back in October and dropped the car off to be fixed extended warranty company denied it first because I had “racing tires” even though those were the ones I had from the dealership. Then they said they denied it because it was catless. So I picked up the car today and needed a jump off the lot drove to get something g to eat left car running out of habit got in the car and hit the on off and car shut off and would not come on tried to jump it and then all kind of error messages came on

who is the ex warranty through?

 

[DARTHSHO]

US warranty

This is the second 3rd party warranty I've seen issues with in a year. Unless yours was posted twice. Always recommend a Ford ex warranty from a discount seller. Also recommend watching modifications when going for warranty work. How much did they charge you for the HG work? How many miles on it?

70k miles and I took it to my friends performance shop

When i picked up my sho from Ford for steering rack the battery was dead and needed it jumped. When i had my engine installed the battery was dead before my shop guy pulled it in and after it was done and sitting. My car sits in the garage alot as i dont daily it. I never have anything plugged in as i have a phobia of leaving things plugged in. And the battery dies all the time in my garage over a month or so. Even on a new battery.
I think its just the way the cars are when they sit. Something drains them down little by little.

I have a short I don't have time to chase and installed this quick neg disconnect in the meantime to keep the battery from going all the way dead. Just turn the **** until the hood light goes out and turn the other way to use normally. cable stays physically attached to the battery terminal
