hi, the car is a v8 3500 with sdi heads and gearbox, has lucas electonic distributor, i seem to have problems with trying to keep engine running .The timiming is checked at 6 tdc staticaly. It looks as if the ballast resistor under the coil was bypassed with a live red wire to a white and black wire then on to the distributor. the coil and distributor has been checked and sparking well. would appreciate any help or a wiring diagram .i .would like to take it to the enfield pagent if possible at the end of the month.
