Quick one: Installing Cardone reman Dizzy question?

[Mark N]

Is the consensus that I could potentially connect to the e12-80 module which is currently attached to the old ZX dizzy? Maybe just attach it to the wing, adjacent to the coil.

If so, then the question becomes just how to wire that correctly.

Going by the photo below, once the mounting screws are removed the E12-80 module should be attached to the pick-up by two wires.

It may be possible to attach the wires from the 280Z to the the E12-80 module using the same posts.
However, the pick-up styles are different between the 280Z and 280ZX distributors.
As for wiring the E12-80 module to the coil, there is a diagram at the end of this guide for early cars.

I don't know about a 280z but the 280zx dizzy is supposed to be used with a 1.5 ohm coil, many after market ones sold for electronic ignition purposes are 3 ohm, as i understand it the 3 ohm ones work well enough but likely won't last as long in regular use.

Just to double check If you have the module I’ve attached in the photo .
(It’s the same as the one I’m running.)
When I wired mine I Simply took a wire from the B terminal and connect it to the + poss side of the coil and connect the C terminal to the - neg side of the coil. (This module is all self contained)

I’ll need to double check, but yes, that looks like what is along side the dizzy.

Thanks for all the tips folks.

Having done some research when I swapped my mech dizzy to electronic a few years back I think you will find that the e12-80 module is not compatible with the 280z dizzy. As said before, the pickup and the electronics are different possibly because of all the emissions stuff in the US. The transistor module is different to accommodate it.

What was wrong with the 280zx dizzy in the first place to make it faulty? The faults are usually in the pickup reluctor or the module. Did you test them?

I know you have invested in another dizzy but unless the shaft is worn I would try repairing the 280zx dizzy. You should still be able to get hold of the bits. It is more reliable and easier to wire in.

Just echoing Paul’s comments above. Electrically there are only two components in a 280ZX dizzy that will fail. The module pack, which are quite hard to kill and the pick up coil which is pretty fragile. The coil is about £8 from rock auto

Mechanically wise the only other point to look for that will stop the dizzy working properly is the air gap on the rotor pick ups for the coil. These need to be equidistant all round. This is an easy fix.
