Clicking Noise from Engine Block ?
Got back from a week away to find my TJ battery flat as a pancake, wouldn't even start with jump leads without a 10-minute charge. It has now started but there is an unusual clicking sound coming from the engine - a soft but definite click every quarter second or so. Any idea what this might be ?
I recently had a bass amp fitted, and it has no physical on/off switch. Can this drain the battery ?
