One of the first things to happen is a rewire of all the non-standard wiring - with an emphasis on fuses (there appears to be a smattering of in-line fuses spread about the place - I replaced that malarkey with a 6-position fuse holder on the HT) and wires capable of carrying the current. Then a removal of all unnecessary wire. Then the 'relay fix' to the headlights.
After that I will look at the alternator size - I suspect the one in it is a low output one - it looks like the one I removed from the SWB 2a except it has a regulator bolted on the rear of it. The HT got a 65A implant. This may get the same.
The symptoms you mention suggest a poor engine/chassis earth strap. But with a Series Landrover of this age, expect to find all earth connections a bit dubious. As an example, on my 2a I found that the headlights were earthed to the radiator support - which only had a very dubious electrical connection to the chassis. The problem is, Landrovers are bolted together, and while this may give a good earth connection when new, after a few decades ........ And an earth connection to the chassis using a copper tag, bolted with a steel bolt to a steel chassis, is also going to rust.
