Relay XVI -
Hey John - You had stated early on that you had CHECKED the L-Jet Computer Power Relay XVI ? I thought we were well past this component but - for T/S purposes and to eliminate a potential relay problem make up a THREE WAY SPADE JUMPER WIRE. Remove Relay XVI from it's base and jumper socket pins 30 - 87 and 87 together (There is one (1) pin 30 and two (2) 87 pins in the internal relay circuitry). ..... This will provide a good solid +12 volts to the computer and tell you definitely if Relay XVI is or is not the issue.......
Also after rereading the rundown on some of your original problems - you mentioned that the two large resistors near the P/S pump reservoir were smoking. Just to eliminate a potential trouble spot, disconnect and clean the resistor terminals. Then verify that one reads (aprox) 0.4 Ohms and the other reads 0.6 Ohms. These are your voltage dropping resistors used to protect your coil during start and run. Don't mix their electrical wiring positions up.
Keep us posted - Michael
