Hello folks,
Naturally I am interested in the chat on wiring in the MGB but not on a
"Oh that will help me" basis.  When I built my MGB GT V8 I decided that
a cutting-cost wiring loom was not for me.   There is a bod who was the
Triumph's electric systems designer who of course was restrained by
costs.  He was not happy with the end system but the bean counters
were.  So he designed a general purpose /point to point/ system that
would work for any car.  It had a central 'control board' with fuses
and relays. So that went into my MGB GT V8 and yes it was more expensive
than the bog standard loom with lots of fuses and relays - but oh what a
neat system!!!  While it makes the car non-standard it does result in
an incredible electrics. All my many fuses and relays fit up in the
passenger foot well in the 'control board'. Â Â I cannot find contact
details of the system easily but if anyone is interested I will dig them
up somehow.
Cheers
Barrie

If you have two wires to the flasher and do not find an orphan wire up
in there somewhere, that is what you have to work with.
Have you established that you have 12V to one of the wires on the
flasher? Paul said that the two-pin flasher is in series with the flashing
signals, so 12V on one of them when the signal switch is right or left turning
is required.
While you are doing this work, ignition will be on, so be sure to
disconnect one wire to the coil.
Have you been able to establish that there is voltage to the signal
sockets?
