Dear All
Half of the fused circuits (fuel gauge, temp, indicators, wipers etc) keep going off. I can change the fuse on that side and restore the functions. But the
old fuse doesn't look like its blown and, if I test the fuse, it carries a current. So, I can swap fuses and the circuit doesn't work again. All of this is
in the garage. As this has happened before (after the calamity detailed below) the whole thing will restore itself after a min or two when I am driving and
stay OK for 100's of miles (but not tonight - it's too late).
This first began to occur after the column light switch collapsed. When I replaced it I started to have the above trouble on the other side of the fusebox
from the lighting circuit.
I have an alternator conversion and, I think, a non-standard voltage regulator. This is the thing sat next to the fusebox behind the battery. It isn't the
regulator shown in my manual - it appears to be just a small, sealed aluminium box but with the correct coloured wires going into it.
By the way, all of this is happening on a 1969 mkII Vitesse.
I think that the, somehow, the regulator doesn't deliver any current until, say, the battery or something is fully charged or summat.....
What is going on?

You will more than likely find it's a duff connection to the fuse box or at worst the box itself is duff. I don't have a fuse box on my car so can't
tell you the wire colours but as the whole of one side goes down I would start with the live feed to that side of the fuse box. Unplug the wires and
clean the connector on both the wire and the fuse box with a wirse brush or emery paper. As you unplug each wire you could well identify the problem
straight away as there's a good chance they will either be loose, breaking off, or badly discoloured with corrosion. I also recommend a thin smear of
Vaseline when you plug them back in as this helps prevent them re-corroding. Also check each connection is a tight fit.

Thanks for your thoughts. As today is pretty grotty, I guess I have no excuse not to go through it all wire by wire. Will make a start once I get
the car back from Ludlow Castle (the Festival of Transport here today with, perhaps, 100 old motors). Why are you not here, I see you're a local
lad?

Simon, I didn't even know it was on. Mind you it would have been dificult as it was my daughters hen night last night so we've got people
staying over.
