Chris - the turn flasher is not independantly fused (although the hazard
flasher is),
it shares the green circuit i.e. the second fuse up in the mainfuse block.
This is the
same circuit as the fuel gauge, so a full ground on the output of the flasher
could be
dragging the green circuit down and affecting the fuel gauge. In theory this
should
blow the fuse, so the first thing to confirm is that the correct fuse is in
place, and
not a length of six-inch nail or similar. The other possibility is that there
is a
poor connection somewhere in the green or white circuits that is limiting the
current
to less than that required to blow the fuse, but is still enough to burn out
the turn
flasher. This would cause the nominal 12v on the green circuit to fall
significantly, check with a volt-meter on the green and white circuits. To
save
burning out flashers jumper *briefly* from the green on the turn flasher to a
heavy-ish
load like the headlights and check the voltage. You seem to have at least two
faults
here (excessive load on the turn flasher and bad fuse or connections in the
green/and
or white circuits) and may have others to find and fix before you get your turn
signals
working.
Good luck,
PaulH.
