Installation

Before installation check visually and turn the drive dog or gear to ensure the distributor has not been damaged in transit.


Please see our FAQ page for additional help
Positive Earth Wiring

a)    New Points Distributor.

Before removing the old distributor from the engine turn the engine to TDC No1 position and confirm the position of the rotor arm ( should align with No1 lead ). Fit the new distributor and connect leads etc confirm the rotor arm aligns with the No1 lead, leave the distributor clamp loose enough to turn the distributor once the engine has started and complete setting the timing dynamically and tighten the clamp.

b)    New Powerspark Distributor purchased with Powerspark electronic module installed.

Before removing the old distributor from the engine turn the engine to TDC No1 position and confirm the position of the rotor arm ( should align with No1 lead ). Fit the new distributor and connect leads etc confirm the rotor arm aligns with the No1 lead, leave the distributor clamp loose enough to turn the distributor once the engine has started and complete setting the timing dynamically and tighten the clamp.

If you can't get the ignition to work once installed, try these suggestions:

Check the wiring:
1. Check the coil resistance to ensure that your coil has a resistance of more than 1.5 ohms for our standard electronic distributor (less than 1.5 ohms for our sports/performance module) and remove any ballast resistor present in your vehicle for this measurement.
One of our standard points type coils is recommended for more than 1.5 ohms
One of our electronic coils is recommended for less than 1.5 ohms

If you are unsure about the coil that is fitted to your vehicle the coil should have a minimum primary resistance to that recommended here depending on the you have installed module.
The Powerspark red module red wire connects to positive ( + or 15 on Bosch coil).
The black wire connects to negative ( –ve or 1 on Bosch coil).
To measure primary resistance: Label and remove all wires to coil. Using a digital multi-meter in the 200 Ω mode, measure between coil’s + and - terminals. Allow a few seconds for the reading to settle. For best performance, the coil should have a minimum of 7,000 Ohms secondary resistance (measured from the coil  +ve or –ve terminal to center high tension terminal, in the 20K Ω mode of the Ohmmeter)

2. Connect the Black wire to the coil negative ( -ve or 1) terminal. In the case of positive earth vehicles converted to negative earth ( eg Lucas 25D ) establish the feed wire ( live with ignition ON ) and the opposite terminal is the earth or –ve.
4. Connect the Red wire to the coil positive ( +ve or 15) terminal. In the case of positive earth vehicles converted to negative earth ( eg Lucas 25D ) establish the feed wire ( live with ignition ON ) ie +ve.
5. For testing purposes, no other wires should be attached to the coil terminals, except for the center high-tension lead to the distributor cap.

 

Timing:
You can set the timing dynamically with a strobe light with points ( engine running ) and with electronic system you can do the same.
You can set the static timing approx as before and you will need a strobe light ie +  and –ve to strobe and sensor lead to No1 plug lead to set the timing dynamic and then adjust to max @ 3500 rpm say 24 degree (depends on the vehicle and engine).
The Powerspark electronic ignition module is mounted as near as possible to the same position as the points were, but in some cases the distributor will possibly have to be turned +/- 10 degrees from where it was with points. Setting the timing is recommended once you have fitted one of our electronic kits.
Setting by dynamic is the best and most accurate way to adjust the timing.
