another tail light question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

a few weeks ago i posted about my taillights not working. the suggestion was the headlight switch or the fuse. i replaced both and now only have 1 brake light working.

at the wire connection on the rear crossmember i got 12 volts for 1 of the 4 wires, makes sense. i then moved up to the conection on the firewall to test those for power. 3 of them had 12 volts, the light green had 0 volts.

my only guess is the connector is no working, cutting the power to 2 of the wires. none of the wires are cut.

any ideas what could be the proble for the 2 wires not working and the lack of power to the light green.

you had power on 3 terminals...was that with the parking lights on, and the brake lights on too? If so, then you are OK up to that point.
