The Powerspark 18D2 Lucas 2 Cylinder distributor ignition kit gives increased durability and performance over the traditional points system. Usually fitted to classic twin cylinder motor bikes such as the Triumph 3TA & 350, Norton 88, 99 & Matchless & Royal Enfield motorbikes please refer to distributor casting number to ensure correct fitment.
We recommend using silicon HT leads with electronic ignition ONLY
Using copper HT leads without resistors can cause premature failures to any electronic ignition and this can void your warranty.
Pre Installation Checks
- Please ensure you have a negative earth car if you have the negative earth kit and vice versa.
- If your car has a Ballast ignition you are running a Ballast ignition coil such as a Lucas DLB110
- Ensure there is a good earth to the distributor, ignition kit and ignition coil.
- The Powerspark kit will operate on 6 volt or 12 volt Applications.
- Make sure any Live wires are to the correct side of the coil e.g. auto choke
- Please ensure you have an 18D2 Distributor as show below
Installing the Ignition Kit
- Remove the points and condenser from the distributor on the internal base plate.
- Install new base plate and ensure screws are tight.
- Place trigger ring over the central shaft ensuring a tight fitment do not force the trigger on, if the ring does not slide on easily rub the inside of the trigger ring with a light sanding disc (this is rare)
- Run the wires around the back of the kit making sure they won’t snag when the distributor rotates.
- Negative Earth Wiring:
Powerspark red wire goes to Positive (+ VE, SW, or 15) on ignition coil.
Powerspark Black wire goes to Negative (- VE, CB, or 1) on ignition coil.
1 Switchable live to the Positive (+ VE, SW, or 15) side of the coil only.To purchase negative earth please click add to cart below
- Positive Earth Wiring:
Remove Switchable live feed from the coil and connect directly to the powerspark white wire.

Can you give me some guidance for static timing of the powerspark? I am fitting it to an 18D2 distributor but I don’t have the original points plate.

Hi Nick
The best thing to do is to move the rotor arm around to number one lead and ensure it is on the compression stroke, then that will be your static position and from there you can dynamically time the vehicle.
Simon
Dynamic timing using a strobe is not possible on many of these applications due to the absence of timing marks. The point of switching needs to be achieved rather like the contact breakers opening this could then be used in conjunction with the position of the piston on the compression stroke.
Some earlier systems fitted an LED to aid this process removing a degree of guess work.
Dynamic timing is possible without timing marks, static timing is also possible without timing marks and yes the position of the piston and achieving the compression stroke is the way to do just that. The LED was not very accurate on the kits and you are referring too and hence they are no longer fitted with them.
Can you tell me How do you do static timing on the 18D2 distributor with electronic points please
Static position can be found with the rotor arm pointing to number one and the engine on the compression stroke when that is the case. This will be the correct TDC position ‘Top Dead Center’ from there you can use a timing light to find the correct setting from the workshop manual on the timing wheel/pulley.
I would advise dynamically timing once the engine is fired up however as this will give you the best results on electronic ignition.
