HOW TO CHANGE FROM A BALLAST COIL TO A STRAIGHT 12V COIL ON A POINTS DISTRIBUTOR

HOW TO CHANGE FROM A BALLAST COIL SYSTEM TO A STRAIGHT 12V COIL ON A POINTS DISTRIBUTOR

Stage 1 ;

IGNITION SETUP WITH BALLAST COIL AND STANDARD 45D POINTS DISTRIBUTOR BEFORE MODIFICATION .

{ See photo at end of this article for how initial wiring looked }

{ 1A } Remove the wire coming from the distributor at the NEGATIVE { - } side of the coil and keep it handy to re- attach to new coil if required.

{1B }

Remove the wires going to the POSITIVE { + } side of the coil and tape/blank them up so that the live ends cannot touch anything .

Now tie them up out of the way

Stage 2 ;

Remove coil and replace with a High performance straight 12v coil .

The following link will give a list of part numbers ;

Stage 3 ;

Make a new feed wire with a SINGLE FEMALE on one end , which will attach to the POSITIVE { + } side of the coil , and a PIGGYBACK CONNECTOR * on the other side of the wire which will attach to the white wire at the bottom of the fusebox end nearest the engine . { see photo at the end of this article for position } }

{* A PIGGYBACK CONNECTOR is just a name for a connector to which you can attach another wire . This means that you can supply/receive power to 2 wires from the one terminal }

{ See photo at end of this article as to how it looks like }

Piggyback connectors are available from many companies including ;

.............

Alternatively you can use Stationary Blades on the fusebox as per ;

SBC 2 into 1 terminals

Stage 4 ;

At the bottom of the fusebox REMOVE the WHITE WIRE at the bottom of the fusebox end nearest the engine

Attach the piggyback end of your new wire to the terminal where the white wire was .

Stage 5 ;

Now attach the original WHITE WIRE to the piggyback connector you have just connected to the fusebox .

Stage 6 ;

Attach the SINGLE FEMALE end of your new wire to the POSITIVE { + } side of the coil

Stage 7 ;

Attach the BLACK wire coming from the distributor to the NEGATIVE { - } side of the coil

Stage 8 ;

SEE PHOTO AT END OF THIS ARTICLE SHOWING HOW THE FINISHED WIRING SHOULD LOOK . { I had to try to amend the drawing I did for an electronic distributor convertion }

MAKE SURE THAT THERE IS NO POWER TO THE COIL WHEN THE IGNITION IS SWITCHED OFF

Stage 9 ;

Make a copy of your new wire and carry it as a spare .

.....................

You have now bypassed the ballast system and you now know that the power is coming direct from the battery via the ignition switch .

NOTE ;

If you wish to return to the original ballast setup it is very simple .

Since everything is visible and easily got at , it is just a case of ;

{ 1 } Removing the new wire ;

{ 2 } Reconnecting the original white power wire to the fusebox ;

{ 3 } Disconnecting the new wire from the distributor at the negative { -} side of the coil ;

{ 4 } Replacing the standard 12v coil with a ballast coil ;

{ 5 } Removing the tape from the original power wires from the harness

{ 6 } Reconnecting from the original power wires from the harness to the Positive { + } side of the ballast coil ;

{ 7 } Reconnecting the original wire from the distributor at the negative { -} side of the coil .
