I have a VF Commodore HSV Redline V8 which continues to get a flat battery! A. No lights or accessories left on. B. Have tried a new battery - still have same issue, I believe the VE Commodores had a similar issue. It turned out to be a computer/alternator problem from memory.......... C. Only [ 40+000ks on the clock], RAA called out if stands for 2-3 days as battery won't even allow ANY electrical units to operate. Comes good for a day after 50 -100km run. Any one else had this happen to them & get it resolved?
