Yes, I'm around there. Not had much time today, but did hook voltmeter up. 15v from alternator, no difference across battery between engine running and not, around 12.6V indicating a poor connection across starter. Main battery earth and all auxiliaries cleaned with no difference. Am favouring Steve's input and will clean/ check all leads between battery and alternator on Sunday, they are very oily! The bit I am struggling with is 15v from alternator going to ignition bulb, why does it light up? Is it because alternator is supplying a higher voltage to bulb than it receives from battery. So there is a nett 2.5 v across the bulb. I had always assumed light glowed when battery voltage was higher than alternator output. Guess it's all logical unless a diode is present preventing a reverse current. Some of this is rhetorical haven't really got my thoughts together yet. Still will get there. PS Am sorry that me posting this has caused other 2+2's to come out in sympathy 😀😀
