[Mgs] flasher unit help

[Paul Hunt]

MGB, I presume.  They are behind the dash attached to the firewall, the 
lower edge in front of the driver on my 73 RHD.  It should push into a 
spring-clip and have green and light-green/brown wires.  It's that which 
plinks when you turn so needs to be in the cabin to be heard.

If you had upset something by removing the front turn signals - which is 
possible as they earth through their mounting screws - then you would have 
had to have done the same thing to both if neither side works, and both rear 
lights would still glow but not flash.  If nothing at all is happening it is 
coincidental.  When you find the flasher unit bridge the two contacts with 
the ignition on and the turn switch moved to first one side and the other. 
If both front and rear light but don't flash, the flasher unit is faulty. 
If still nothing happens, check for 12v on the bridged contacts at the 
flasher unit with the cob.  If you see it the problem lies towards the turn 
switch.  If you don't see 12v then the problem is more than likely in the 
hazard switch, the 12v gets to the turn flasher unit via this switch in the 
off position, and these switches are so little used the grease hardens and 
can act act an insulator.  Flipping the switch back and fore can sometimes 
fix it, but in the end I had to dismantle the switch (in a poly bag to catch 
all the bits), dif out the old grease and put in fresh.
