So I have gone out tonight with the multimeter. At the bolt at the back of Alternator I get 12.2 v. (Probe on bolt and other probe on engine block) At the battery (on the two terminals) I get the same. So I think that sounds like alternator is okay

interestingly it won’t start today showing signs of flat battery. But I guess because it’s been stood for a few weeks.

just as an extra I’ve read a few posts about people noticing a current draw by alternator when everything is off. How do I check for a current draw? Thanks

So found a way to check drain and done so and there is less than 0.3 amps when using 10amp scale and 11 when using micro amps plus alternator is cold to touch. So I am assuming there is not current drain.

the battery is unknown age and although a 072 is only 563 CCA so I guess a new battery would be in order.
 
When I had a similar problem i disconnected my battery negative lead, and put my test meter probe s between the negative lead and negative battery terminal. (So the test meter is inline and set on amps).
Make sure there is no load on the circuit (obviously). I think my earth leakage was 0.03 amps. You ideally want below 0.05amps. So you do have an earth leakage fault.
A 0.3amp leakage will drain your battery in a couple of weeks.
You can systematically start pulling fuses to see if you can isolate the fault.
Hope this helps

Thanks will do that.

So I’m clearly a dunce. Just gone out again with the mm ser to amps on the 10A scale I get a reading of 0.011. So I think I’m fine.
 
Just checking back in to say thanks for the help.

I purchased a bigger battery and once fitted and having checked the four fuses in the engine bay, and the bolts when running it all looks good.
So now to check the relays in the boomslang.
 
Ps although interestingly in all the checking recently and when first starting yesterday I didn’t think I had dim dip enabled. But clearly the relay decided to start working during yesterday’s drive.
