Question about 1987 Jaguar XJ6
After replacing the battery twice and having the car completely checked out by a local Jag dealer, I still have problems with irregular starting. It runs for a short time then won't start at all. Something electrical is draining the battery. Help!!!
Have you checked the alternator? The alternator may not be charging the battery. With engine running, check the voltage at the battery (it should be ~14V). If it's less than that, your battery won't charge properly. You can take your alternator to auto store to have it load tested also to be sure. Sometime alternator issues don't show up until it gets hot. Defective alternators have also been known to drain the battery after the car has stopped.
