Hi Richard it was the wiring info I was after, I've got Durite diode type relays. I have checked the operation of the piggybacked solenoid and all is ok when i energize it by linking the main motor +'ve to the solenoid terminal +'ve. Problem is when i operate from the key, the starter relay just clatters in and out. As mentioned above I think I might have "mislaid" an ECU 12v feed or wiring harness connection.......tomorrow is another day🤐
