2.2 Battery Dead, again.
I have a 2.2 sport (no HFT module installed that I know of) that has been discharging its battery over night.
This has been happening this for the past few weeks and I am at the end of my tether. Would you guys be able to offer advice with this. Here is everything done so far:
1. In uni working late one night the car was dead, I got a friend to Jump it and I made it home at 1am.
2. The next morning at 8am it worked fine.
3. Two days later of no use the car was dead again. I got a new 74/680 096 battery to replace as the few mechanic friends suspected this was the problem, especially as the previous battery was 8 years old.
4. For a few days the car worked fine but then needed jumped again. After which my uncle and I performed an open-bonnet parasitic draw test. 0.00A was being used up to 5 minutes after locking the car (maybe I need the bonnett closed to properly perfom this test?). Next suspect, either a duff battery or alternator.
5. 3 days later the car was dead again so my uncle and I jumped it and were preparing to being it to the garage. Shortly after jumping, the A/C relief valve popped and gassed the driver side of the engine bay, also the alternator was providing some strange noises and a wonderful cooked smell.
5. Brought the car to the local good mechanic, he identified the alternator was at fault and got a replacement installed and fully topped the battery.
6. The next day it was dead again, luckily I got a friend to charge the batt but still haven't tried to start it/restore the batt.
And thats where we are now.
I have read that an OMRON relay in the fuse box can cause the A/C to drain the battery and over-pressurise the system. I have removed the relay and it does have an audible rattle BUT on performing a continuity test there is no power flowing between the A/C pins.
Do you guys think this is what may be causing the problem??
Also, is it OK to drive without this relay in the car??
Thanks for your help
