Hi everyone, I'm starting a new project car , wish me luck. One final issue before I have my xjr repainted .
I'm not sure how long , probably a couple days I get a dead battery. I put a meter on it , checking for drainage and found a draw of .18 amps . I'm not sure if this is high or not with all the computers on this thing . If I pull the body controll module fuse it drops to .01amps.
I've got a parts car so I could switch it out ,but I thought I'd try here first .
Any help is appreciated !
Thanks

There is a time that as you remove the key and make a switch in the key barrel before the car goes to sleep . Can't remember how many minutes . Yes the BCM is involved . Lets start with the key switch .
Findings on ignition Switch : Jaguar part # LNA6507BA
By removing connector FC54 9 inches straight forward of switch found ground pin 5 contaminated , cleaned
The pin side of the connector pops off the bracket straight down to be able to hold in free space .
Black wire socket position 5 to ground = 0
.........On the pin side of the connector :
Black wire pin position 5 to pin 1 key position 2 = 50 ohms Run position
Black wire pin position 5 to pin 2 key position 1 and 2 = 0 ohms Acc position
Black wire pin position 5 to pin 3 key position 3 = 30 ohms and bad large waver as moving key radially ( needs replacing later ) Starter
Black wire pin position 5 to pin 4 key insert = o ohms , key removal = open ohms this is the security ECU input
