Pinto Dizzy Wiring

[Guest jasper3]

Now then! does any know if the little black module is needed on the sierra loom?I seem to have more wires than needed it just a standard set up to me! I am making a new loom up and just wondering whats its for!any ideas before its in the bin!

Post up a pic

It may be a ballast resistor?

[IanS]

little black box with 5 to 6 wires is probably the electronics for the distributor.

[Guest jasper3]

Its a black Box flat shape mounted on a backing plate it has six wires! i know where they all go except the white one?

[IanS]

There are 2 or 3 wires to the distributer

earth (brown) not always fitted at distribter end.

Signal 1 green/yellow

Signal 2 black/red

 

coil - and tacho green

coil + Switched 12V Black

 

Earth Brown

 

note there are 2 earth connections

Ya dont happen to have a wiring diagram do you! So i can make sure i have it right thanks for your help!

Here's a copy (attached) of the Vicky Green loom drawing as a .pdf that shows the Ford Motorcraft amplifier.

 

There is also wiring info' on this post: http://community.rhocar.org/downloads/wiring/Hoodwire.htm See the "Ign & Charging 2" page that may help.

 

 

I have not used the Ford module though as I have an old dizzy with traditional points that seems to work well.

Basically you just take the switched Ignition feed to the +ve of a ballasted coil, then the -ve is switched by the points to ground.

You just need the standard capacitor (condenser) fitted across the points.

Keeps it simple and seems to work fine.

 

You could also invest in one of the electronic ignition modules that fits inside the dizzy, but beware they can cause issues if you want to take the rev counter feed from here.

It is not an issue if you have a rev counter output on the alternator.

Vicky green loom is a good help! It seems to be wired as the diagram says it is the wire that goes to the starter thats not wired to anything! It looks like there is a live spliced into the coil so it must be getting a feed from it! Thanks again

[Guest jasper3]

Oh there is a feed for rev counter on neg side of coil

[tractor]

get a bestek dizzy will transform car and no need for amplifier

I am at the exact same stage regarding wiring but have the distributor as the picture below, it only seems to have 1 wire out, how does this work with the motorcraft unit?

with a supressor capacitor on the outside it looks to be points based.

so no need for motorcraft unit

[Guest Kitcarkris]

So how would this work with wiring? Anybody with a wiring diagram would be a life saver?

[Longboarder]

Agree. Kris There should be two wires to the contact on the dizzy points. One goes to the capacitor shown on the outside of the dizzy pictured, presumably the black wire in the picture.(The body of the capacitor is earthed by being screwed to the shell of the dizzy). The other goes to the negative contact on the coil. The coil gets its power from an ignition live source to its positive terminal.

OK Pic of a points distributor (from an old V8 and with the capacitor inside the dizzy) which shows the connections. One from the capacitor and one from coil neg, combined onto the sprung end of the moving point arm. No other wires needed. Note that the moving arm is electricaly insulated from the base plate of the dizzy and the wire connections are insulated from the fixed point arm but do connect electricaly to the spring. The only route to earth from these wires is through the points when they are touching. This make and break between the points is what 'fires' the coil.

Points fixing and adjusting screws not present and the braided earth wire not connected at one end. It should be held by the points fixing screw.

That's great Nigel, much less wiring than anticipated, although once through IVA, think I will regret saying that as I swap for twin 40's...
