My battery drains completely after around 15 minutes, I bought a new one and it does the same, no warning lights or low battery warning. I did have an ingress of water through a broken finishing plate on the offside rear light cluster. I have cleaned and dried the area replaced blown bulbs to no avail, in the morning I shall unbolt the earth and check that. Any other suggestions as I recently had another electrical fault and my local Jaguar dealer traced and repaired it for £850, I am determined not to go down this route again. Any ideas what else I can do?
I have spent almost £7,000 on things going wrong since I bought it 2 years ago
