Electrical problems can be the most elusive problem in any vehicle.  Often a 
bad ground on any item can cause weird happenings.  A turn signal can cause 
all lights to flash or headlights to go out.  When an circuit is searching 
for a ground it can be through any filament or coil in the vehicle.  The 
best solution is to make sure that the frame, body, engine, etc is properly 
bonded to the ground terminal on the battery.  Cleaning ALL ground 
connections is not always enough. Corrosion can invade any connection.  An 
easy diagnosis is to run a ground wire to any suspect light  or gauge and 
see if this solves the problem.  My experience with restorations and repairs 
also has discovered another problem that is difficult to solve.  A given 
wire can show twelve volts but the circuit does not perform.  A single 
strand in the wire can carry 12 Vts but no amperage.  If your test for 
voltage shows 12 vts bur will not work try a load test on the wire.  You may 
be surprised that corrosion or a break in some of the strands of wire may 
not be allowing the circuit to work.
