Turn Signal Issues

I need ideas/help/suggestions/miracle. So I am trying to get my front signal lights to work on my 77/79 hybrid(77 grill on a 79 truck). To give you the run down I have: replaced a bad turn signal switch and have traced power to the turn signal sockets.(Done this to both sides)

I have 12 volts going into the sockets while grounding straight to neg. battery terminal. What I don't have is any voltage coming out on what should be the ground wire(black wire) from the socket. New bulbs so I am thinking the sockets could be bad, but wondering if there is anything I am overlooking? Don't want to replace a part that is still good you know.

Good advice very much appreciated!

Re

why don't you use a test light to probe through the wire insulation to the copper wire on the ground side of the socket '

ground one end of probe


anywhere on the wire where the light comes on you have a good connection to battery

keep probing along the wire until
the light does not come on any more

the wire break can then be found between the probe where the light was on and probe where light was not on:

hope this makes sence

if no power at outlet of socket then socket is bad

unless the pissing contest between Dorman and the parts stores has intensified, dual filament bulb replacement sockets for turn signals are around $7. Easier to replace the whole socket. I've had a couple that looked good but the connection between the socket ground and the ground wire from the socket was bad.
