I guess a faulty ignition switch is a possibility. Have you confirmed it's the ignition relay rather than the accessory relay?
I think even with the relay activated, *something* needs to be *on* for the battery to drain.
Ignition relay? What model is the car?
That’s the fuseable link you are pulling outHey Jon thanks for your reply!
Yea its definitely the ignition one. If i pull the cable on top of the relay then connect the battery it doesnt click so I assume this means its that relay?
Ill check out the switch although nothing else works in the car when its on bar the clock. You have to turn the switch a click to make lights etc come on as id expect
The reason I asked is that I'm not aware of an Ignition Relay. There is an Accessory Relay as Jon asked earlier in the Thread.Hey Rob, its a 1978 UK 260Z

The Alternator voltage regulator sits under/behind that black bracket, in your picture you can see one of the screws holding it in place poking through from the back.
Honestly, no idea how they work or why it would click. Checking and cleaning the alternator connections and the regulator multi connector would be a good start i guess. The regulator is a mechanical/analogue device, no fancy electronics and there is also no relay involved, certainly never heard mine click and don't believe they are supposed to.It's that that's clicking on I believe. What would be causing that?
I would unbolt that bracket and check it is just the voltage regulator behind there, if it is, unplug it and see if something else clicks!The clicking comes from right below where that ignition fusable link is. Under the bracket it sits on.
Been told it could be the alternator voltage regulator?
Regulator, externally as for 240z and i believe most 260z, internally for 280zx and IIRC for later 280zSo after a conversation with @Fairlineguy we got to the bottom of it! Apparently Datsuns had a couple of different alternators one with something built in and one with whatever that is, not built in.
