79 right front turn signal problem

[dart340]

First off hello. I have been lurking for awhile and have solved a lot of my problems with the help of this forum. I've been sorting out the electrics on my 79 and can't seem to resolve one issue with my lights. When I turn on the right turn indicator it causes the left side markers, and left tail light to flash as well as the right turn indicators. Furthermore, if I turn on the parking or headlights the right turn signal switch does nothing. Left turn switch and lights work normally. Also with the lights on the rear right turn indicator light is on at all times. I've gone thru every ground, and then back thru every ground. Pulled the fuse box out, cleaned all the contacts and hooked everything back up with no results. Just last night I discovered if I pull the bulb out of the right front turn signal all the problems go away. I tried a different bulb and the problem came back. So any ideas? Could it be that socket is bad? Any suggestions would be welcome.

Anyone know offhand what bulb type is supposed to be in the front turn signals of a 79 spider? Are they supposed to be dual filament bulbs?

Yes it is a dual filament bulb. I use 1157's. I don't know if this is what Fiat recommends, but it works good.
