Looking at the Oliver 1550 shop manual schematic, there is white wire from starter solenoid going to wiring harness, anyone know where the white wire terminates. Looking at the diagram there is white wire terminating at the positive side of the ignition coil and also joins with an orange and purple wire inside the wiring harness. My rebuilt starter has a three post solenoid (where the white wire would connect on solenoid) as the diagram depicts. I am told by the starter mechanic no need for the fourth post on the solenoid as it is only used for grounding and the new solenoid grounds to the starter housing. Without a white wire from the solenoid to the coil I plan to run a white wire from the ignition switch "I" post to the ignition coil. I am using the diagram from another post (rvirgil_KS Oliver 60 Need Wiring Help !!!) to complete the starter solenoid wiring. Anyone see problems in this method on the Oliver 1550 Gasoline.
