I also rewired the main battery earths today.
New terminal on the negative of the battery, new connector on battery end & gearbox end of that earth. New connector on the earth from the gearbox to chassis. Also installed two of the 'big 3'. These are the alternator output -> battery + terminal & the battery - terminal -> the chassis via top mount.
The issue of dimming clocks when I put on blower motor is happening still.
Will add an engine to chassis earth tomorrow and see if that helps although I very much doubt it.
Starting to get lost for ideas, will try a known good battery on it & see if there is any difference although the car starts fine etc on this one.
