1972 911T Turn signal issues

[Balloonmeister]

1972 911T with 3.2L motor now installed. When I turn on the left turn signal, the left green arrow in the tach flashes brightly several times and then switches to the right arrow in the tach and flashes dimly. Sometimes it may switch back to the left arrow, sometimes not. The turn signal lights on the outside of the car all work properly all of the time. Where do I start?

Good question...the outcome will be interesting. I just put power on my son's '65 and the turn signal arrow blinks in the correct direction, although there is a dim "echo" on the other arrow.

Check the housing earths, correct wattage bulbs and then the flasher relay. Simple really. It's important all the bulbs are in place including the side marker ones to ensure the correct load on the flasher.

I had a similar problem in my 1970 911T. I replaced the flash and turn signal relay but the problem continued. Cleaned the left side turn signal bulbs contacts and still nothing. I then replaced the bulbs and the problem was solved. Moral of the story: the fact that the bubs go on does not mean that they are 100% OK.

I recommend Hella bulbs, not Narva or similar generic types.
