James,
A workshop manual does not exist. I've never seen a wiring diagram either, although I thought someone produced one for the 603 at some stage, which would be very similar.
If the Beaufighter wiring is anything like the 411 wiring then it leaves a bit to be desired, mainly in the form of relays! Ideally almost everything should be on a relay so that there is no significant current flowing through any switches.
Some of the other problems you describe could be earthing issues, which can create some very strange effects on car electrical circuits. Poor earthing can also cause damage because it usually results in current flowing through things it's not meant to flow through!
First of all I would check the point where the battery earth/negative connects to the body. Make sure it is a solid, clean connection. I would also consider running a chunky earth strap to the starter motor or at least the engine (this cured starting problems on my 411).
This might cure some of the issues. If not then you need to then look at each one in detail, paying close attention to the connections, at the accessory itself and the relay if it has one.
NB: I would advise against turning on the rear screen heater again until you have ascertained that it is connected correctly. I believe it is connected via a relay on the 411 so it is likely to be similar on the Beaufighter. It should also have it's own fuse, circa 35Amp.
Let us know how you get on.
Cheers,
Kevin
