MG Car Repair: wiring issue, fuse box, ok check

Question
I have a 1976 MGB .all the marker lights worked .did a few repairs on brakes and stuff put car back on the ground drove it once now the markers went out but I have headlights and brake lights.I'm puzzled..thanks Frederico...

Answer
Hi Frederico,

The side markers are connected to the parking lights so if the parking lights are out also, go to the fuse box and check the end fuse that has the red wires on one end and green w/red tracer on the other end. If the fuse is ok check for power on the green w/red and if it has no power with the lights on test the light switch out-put power on the green w/red wire.
