Electrical help needed, front blinker
'65 sb roadster, back blinkers work both sides, driver side blinker and turn indicator light good, but passenger side front blinker and right side turn indicator light dead. Parking lights work fine in front.
Did a search and tried ground wire from front socket to radiator support, no blinker or turn indicator light.
What did I leave out? Any ideas?
Thanks.

Using a test light back probe the dark blue wire on both sides of the signal switch connector while operating the right turn signal. If the test light lights here then remove the right bulb and carefully probe the contacts inside the socket. If it does not light then it could be a broken wire or a bad connection at the firewall connector. If it does light it could be a bad socket. There is a spring under each contact that could be bad.
I always connect the ground end of the test light, using a jumper lead, directly to the ground terminal of the battery. Also before I start my testing make sure the light works by probing a fuse in the fuse panel.

All the lights up front are grounded at the same place on the radiator support. IF you have a bad ground, it will be at the connector where it splits. The voltage for the front blinker comes through the right hand bulkhead connector up to the connector on the driver's side front fender in front of the tire. The wire for the driver's side blinker is light blue. Then the wire for the right side blinker (dark blue) goes across to the socket for that side.
HOWEVER, the voltage for the dash indicator comes off the turn signal switch straight to the bulb. So if the indicator is not lighting when you turn to the right, the most likely problem is either the contact in the turn signal switch, or at the harmonica connector coming off the turn signal switch. Check to make sure it's fully seated. The rear blinker doesn't go through that bulkhead connector nor does it feed the dash indicator, so your problem is most likely at or inside the turn signal switch. The dark blue coming through that harmonica connector feeds both the front filament and the dash lamp. Start there.
