Post Dodgy Charging
I've noticed a bit of flickering and dimming when I've had the lights on recently, so had the multimeter out today to have a quick check what's going on.

Car off: 12.4v after standing, so battery seems fine.
Idling/revving with nothing on: 14.4/14.5v
Lights on at idle: 13.2/13.3v
Lights on revving: seems to top out around 14.9/15v, no signs of battery boiling currently.

I'm going to check out the connections to the regulator tomorrow but haven't got a spare to try out, is it also worth checking the alternator brushes are alright?

Thanks.

Been out and checked the light connections today, as you predicted pretty ropey. The switch looks OK.

I've cleaned them up best I can which has helped a little bit and reduced some of the flickering, but while I'm on, has anyone got a diagram/instructions for converting them to relays? It's something I've had in the back of my mind for a while which I know should be fairly easy, but just want to make sure I get it right.

clean your connections mass cable to the gearbox and also the connexion between the altenator and the manifold.

take the lighting switch apart and polish the brass drum inside it corrodes and causes resistance make sure the dim/dip system has been disabled-u can tell if the switch is the prob as it gets hot after a time with the lights on
if it needs cleaning
