If the left-hand flashes OK then it's not the flasher unit, there is one =
flasher unit for the hazards and one for the turn signals.

When one side glows but doesn't flash the problem is in the circuit that =
side.  The original flasher units needed a certain amount of current to =
flash properly, and if that current reduces they flash slower or stop. =
If one bulb fails the other will glow continuously, but that should be =
obvious by checking both ends.

If both are glowing then either one or both bulbs is too low a wattage =
or there are bad connections in the circuit.  These need patience to =
resolve by measuring volt-drops through the circuit, this may help =
http://www.mgb-stuff.org.uk/electricstext2.htm#fault2

However if this only started when the turn switch was replaced you =
should check the connections there first, making sure the two connectors =
are fully pushed together and none of the pins have been pushed out of =
the back.

  A friend is having problems with the turn signals on a 1980 B.  =
He=E2=80=99s replaced the left-hand switch unit (turn signals & horn).  =
Left-hand signals flash, and 4-ways flash, but the right-hand signals =
only light steadily.  He=E2=80=99s located the one flasher unit, but can =
hear another one clicking somewhere and can=E2=80=99t locate it --  =
where should he look?
