Hey mates

A few years back I did the ZX dizzy conversion on my Z. This past weekend, when checking everything I noticed that the little tab on the front of the distributor - near the vac advance - is not connected to anything. Is this supposed to be a ground? Does it actually do anything to performance/drivability? Picture is not of mine, but I'm speaking of the tab located on the housing.

Thanks

That would be for a dedicated ground wire for the distributor body. The 280Z's have a wire that attaches to one of the distributor mounting screws for the same purpose. It just guarantees good grounding in the case of gaskets and sealing materials isolating the distributor body from ground at the mounting surface. The ZX FSM shows the screw being used for ground for test procedures. If you still have the black ground wire to the mounting screw for your 280Z setup then you don't need it. I check my grounds with an ohm-meter myself, to be sure I have minimum resistance, even if they're connected correctly.

That said wire is sadly gone, fell off when I was doing the front cover a while ago. Should I just add a ground to the distributor?

Thanks
