On a 25D4 the coil wire from the harness is white with a black stripe
and is external to the distributor and connects to a spade terminal on
the outside of the distributor. Internally there is a brown
cloth-covered tinsel strand wire from the spade that sits under an
insulator and nut on the points. It needs to be electrically isolated
from both nut and stud.
Whilst on the 45D4 it is black, is the coil wire and does pass through
the distributor body, it is factory-attached to the and is the live side
not the earth. It has a tab that slides under a folded over section of
the points spring, there is no nut, just an insulator that sits between
the spring and a support. A short length of wire is external ending inÂ
male spade connector connecting to the white/black harness wire.
Originally the 25D4 had an earth wire spot-welded and riveted to the
points plate, 45D4 used a through-hole terminal under the condenser
screw so that screw needs to be long enough to hold both securely. But
make sure neither points nor condenser screw are too long or they can
foul the weights and cause running problems. Like the 25D4 internal coil
connection the earth wire was originally a very flexible brown cloth
insulated tinsel-stranded wire going to one of the screws securing the
fixed part of the points plate to the distributor body. Not generally
available, if they (both coil and earth wires) fail standard wire
probably won't last very long as the points plate is continually
twisting back and fore as the throttle is opened and closed - if you
have vacuum advance.
Unless you are replacing the screw that came out make sure it will fit
before putting the condenser in position.
