Hello My brothers MGB tailights were out so a friend of his fixed them....now his turn signals are out? I'm a TR3 guy so not too familiar with the B. Any common "Lucas Prince of Darkness" issues with MGB tailights. Bad gound??? Karl
 
Yep bad ground.....look around the license plate for a ground & there may be others.
 
Also I would check to make sure the "friend" didn't accidentally unplug any of the connectors to the turn signals.
This can be easily accomplished by tugging around on the wiring back there. Seems like if the signals worked before and they don't now something may be disconnected.
 
Wiring diagrams are available at https://www.advanceautowire.com click on stock schematics.

Do the wipers work? If no, then the problem with the turn signals might be the fuse.
Do the hazards work? If yes, then the problem won't be at the bulb sockets.

Common problem is corroded internal contacts in the hazard switch.
