In both of these photos there appear to be what may be fusible links. I hooked up the battery and there was a pop followed by a good deal of smoke. I could only feel that the Orange wire going to the ignition relay was very hot. I did not see any damaged wires.Where was the smoke show?
Engine bay or cab?
There are two Orange fusible links, or just one?
Was ignition switch on or off?
It might be the relay for the choke. These engines had full 12 volt electric chokes on them, and they were controlled by the computer. Of course the computer can't handle the current of the choke, so they used a relay.What is the function of the (relay?) under the solenoid?
The key was off. I'm going to take a look inside the truck where the computer was.Where was the smoke show?

Can you take a pic of the solenoid and post it here?
So I can remove that. Now I don't have to worry about where those wires go. My Choke is Vacuum controlled now. One less problem!It might be the relay for the choke. These engines had full 12 volt electric chokes on them, and they were controlled by the computer. Of course the computer can't handle the current of the choke, so they used a relay.
My relay had burnt out long before I got the BII, and someone had re-wired the choke to the s terminal of the alternator. Even though that is only 7v, it seemed to work ok. I have since gone to a manual choke system.
That's the way it came Brand New. I have never changed the relay. It's interesting to see that though. Maybe it would be a good idea to replace the relay and follow that.I’m not sure how much it matters, but the battery and starter connections on the relay are reversed.
