'72 Turn signal woes...

[Pleiner87]

Hello, I have picked up another '72 240Z around a month ago and have been slowly working out problems in the car, like the anoyng problem with my turn signals. My dad had a simalar problem in his 260Z a couple years back, but now I'm looking for a good solution.

When I first started to tinker with it I had noticed that the Green power wire had been bypassed along with the factory flasher unit, in place was a cheeepy flasher unit with a power spliced into a random power wire. I tested the old green power wire and it had no power, wanting to drive my z I put the cheepy flasher back in. A week later I had no turn signals so I took apart the switch and cleaned the contacts and put a good dylectric greese on it aswell, still no turn signals I jiggled the dangling flasher unit and presto I've got signals again... for an hour... to take my mind off of it I removed all of my dealer installed york air conditioning system and ended up finding the perfect plug to try on the flasher unit, once again I had turn signals.

Fast forward to last night I went for a drive and no turns again! I shook the flasher unit again and had signals after that. Today in my parts 240 I grabbed the factory flasher and tried its luck I got a perfect left hand turn but the right was just solid on, I had tried many combos since then and have had no luck for anything. I had noticed that my a/c fuse was a 30amp (I had thought it was a 20amp), and that ran into the flasher, was that too much for something in the turn signal system? Does the flasher unit need to be grounded for it to work?

-sorry for the long description, I thought this back story could help out more.

Thanks Todd

Buy a new electronic flasher unit (3 terminal) ground the (-) or (E) Then connect the white wire to the (L) and the green to the (+)

Make sure all your connections are tight.

The electronic flasher will use less current and flash consistanly without all of the amperage that is normally required bu the old "Thermal" style flasher.

Try that and see if it works. They run about $15 and one of the best upgrades I can suggest for the price.

Great tip Dave, I'm going to pass this info along. The other day I was helping a friend diagnose his dimmer switch problem in his 240Z and inadvertantly activated the turn signal without realizing it. Love me Tender by Elvis started playing. First time I had ever seen one of those. He likes it, I find it annoying. Now I can point out why he should get rid of it.:classic:

I nearly pee'd my pants when I read that!

No doubt, that's pretty damn funny. Even better would be Sammy Hagars "I can't drive 55" At least that would make more sense.

Had the exact problem with the 72 240z. Well almost. Then the left rear turn would not work at all....new wire harness and new flasher. It would work properly dependent on temperature. Turned out it was a dirty non working turn signal switch. Took it apart and cleaned it all with electrical cleaner and re-lubed it. Turns out the front and rear turn signal lights have separate contacts in the switch. It would work properly dependent on temperature.
