Message: <blockquote data-quote="jerry" data-source="post: 56689" data-attributes="member: 931">when I had starting issues this was the post from another member that helped me.Let me start with a text description of how this circuit works. If this won't do, let me know and I'll try to follow up with photocopies of my photocopies, but the print is tiny and I have a feeling they'll not be too legible. Plus I only have dial up connection and they'll take forever to download. With the key on and the run service switch in the run position, seat belt bucked or jumped, seat switch closed and the key in the on position, the orange/white wire on the interlock relay should be energized with juice from the seat belt/seat switch circuit. With the key in the start position, the white/lt green wire on the interlock relay should be energized with juice coming from the post on the service/run switch. If these conditions are met, juice should flow across the interlock relay to the start relay via the white/Drk Blue wire, then to the starter solenoid via the red/white wire, to the EIC pin 10 via the white wire (not via the interlock relay) and the starter should kick. Power should also flow from the light blu/Orange wire to the fuel solenoid on the injection pump. An interlock relay is a part # 86521256 and is $44.33 on the Messick's site.It was the interlock relay on my machine and found out later there were some on e bay for about half price. If you follow this it will tell you whether or not yours is working.</blockquote>
