After a one-year engine overhaul (only the block, crankshaft, head and camshafts remain), my 1978 automatic XJ6 4.2 Series 2 is almost ready to start its new life. A very professional workshop carried out the machining and reassembly and now, having had the engine delivered to my usual mechanic fitter, a last minute unexpected problem has popped up.
I was told to replace the mechanical distributor by an electronic type:
LUCAS CONSTANT ENERGY DISTRIBUTOR CONVERSION KIT - NEGATIVE EARTH
This is based upon the later Jaguar system. This is a brand new Lucas magnetic distributor with an externally mounted amplifier which is mounted on an alloy heat sink plate to eliminate problems due to heat. This distributor is already set up for the Jaguar that it will be fitted to so there is no need to change any settings. This kit is also supplied with a set of sealed for life carbon leads and a Lucas high output coil.
Well… the mechanic has made a mesh and the connections must be totally wrong - for what was supposed to be a plug-in solution - and now neither the fuel pump is working properly, nor the rev counter and some lights.
The question is that the new connections (looks like many old ones before used the negative of the coil) are not clear and, basically, the fitter is lost.
I have requested the support of the provider and I’m sure he will do his best (they always assisted very well before).
Probably the S2 electric connections should be modified when this distributor is fitted.
I would appreciate the assistance of anyone who knows about this and any picture or diagram that can show us what we are doing wrong.
Thank you very much for help.
