HOW TO CHANGE FROM A BALLAST COIL SYSTEM TO A STRAIGHT 12V COIL using the original 45D DISTRIBUTOR

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

Stage 1 ;

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

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

{1B }

Remove the wires going to the POSITIVE { + } side of the coil { Marked { B } on above drawing } 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 straight 12v coil .

I would recommend using the performance coil ;

.

The following link will give a list of part numbers for the standard coils but my preference is the performance coil above ;

...........

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 Fusebox .

{* 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 }

Piggyback connectors are available from many companies including ;

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

SBC 2 into 1 terminals

or SBD 3 into 1 terminals

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

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 ;

Re-attach the original wire coming from the distributor to the NEGATIVE { - } side of the coil

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

Stage 8 ;

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 .
