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
