  1. Hi. Fitted to a triumph t100a , got a spark in static position but no spark turning the engine over, what is the minimum voltage for the system to work, also what coil voltage is required, the coil is 5ohms (12v)


    1. Coil resistance needs to be between 1.5 Ohms and 3.5 Ohms to ensure the item will work. The minimum voltage for the system to work is 6 volts and this should not drop below at any point of cranking.


  2. Hi, I can see the black wire to the coil neg terminal and the red to earth, where does the white wire go to, car is Austin 1100 mk1 pos earth, bought all the kit, fully assembled dissi, coil and leads, fitted dissi, and coil in place, black wire to coil /neg red to earth but do not know where to pick up ignition line, hope you can assist, thank you frank. ps you actually fitted my last car when you were in Park Street, good days then.

    1. Hi Frank
      Something doesn’t sound right if you have the wire colours you are saying for a positive earth application. Can you contact us on so we can help you. I am unable to find your order initially and it would be great to hear from you.

  5. I bought and fitted your positive earth Distributor system for my Sunbeam Rapier, absolutely fantastic improvement to engine , thanks. Im now wanting a TACHO OUT signal to drive my smiths Tacho which I have converted to RVC. It asks for a -ve signal, can you suggest a possible output point please ?

    1. Thank you for your comment.
      It is best to speak with our technical team directly about this by calling the office if you could please on 0157 889 453.
      Regarding the signal your negative side of the coil is actually the side with the Black wire on so please look at this for your signal however not all Smith’s will work with the electronic ignition conversions but we can help you with this when you call.

      Thank you
