    Hi,
    I have trouble with my Bonneville 2003 . I have no spark and my local Triumph dealer can not find the problem so they told thatb it was 95% the CDI and then I changed that and still no spark. I have measured the coils and they seem ok. Ihave new ignition cables and new NGK Caps as original....

    Hi,
    Now i measured the coil again, and I seem to have 8,5 k Ohm on the secondary side....Is this to low?
    I have 5-6 ohms on the primary side.

    The ignition coil values are not always reliable. The HT value is about 18-20k ohms between outputs (minus HT leads) and the LT about 8-9k. The fact yours is low might indicate an internal break. The best replacement is the PVL originally used on BMW twins -
    PVL PART 356 1 OO
    https://www.triumphparts.co.uk/product/ignition-coil-pvl-1200-models-and-bonneville-800-865/ If you can’t find one in Sweden.

    The pick up coil should be about 570 ohms. It is easiest measured at the 2 pin connection just to the right of the battery and slightly below (under side cover)

    Another worthwhile check, ignition on, is that you have battery voltage to the ignition coil +ve terminal.

    HT - High Tension
    LT - Low Tension i.e. battery voltage

    Very surprised that the dealer wasn't able to find that........hope they didn't charge you anything for saying they didn't know what the problem is!
