Thread: Disco 1 3.9 v8 ignition troubles

Hi try pm beeutey he is the wiz on eveything electrical on D1's and the like. His coil conversion is worth every cent worked wonders on mine

Lucas disease. You most likely need a replacement ignition amplifier, this is a very common problem. All the goss on the Bosch amp/module & coil conversion is here (start at the beginning of the thread):

Lucas ignition amplifier replacement by Bosch 024

Remember to check first that 12V (approx) is available at the coil with the ignition switch on, sometimes the immobiliser dies instead.

Cheers mate, I did have someone say that to me, and try directed me to the side of the dizzy or somewhere near the coil for its location however I am unable to seem to find it, the coil it had was a Bosch gt 40 transformer type, if that makes any difference, and I replaced it with a gt 40 oil type they gave me from repco, they product numbered it...

Neither of the GT40 coils is suitable for this kind of electronic ignition. Replace it with a proper electronic coil, either OEM second hand or Bosch BIC290.

Your ignition amp is either on the side of the dissy or on the radiator support panel, behind the coil. A '94 IMO should have it on the dissy. It's quite small and has a vertical upwards plug on it. You may think it's just a terminal block but it's the electronics, in total.

Hey bee, I rang repco to get a price on a bic290 they told me their listings on that coil are for different mitsubishis, would a bic290 still work on a disco
