1. K02 in the power panel goes click when you turn on the IGN switch(one hand on the relay, other hand on the ign sw), but no idiot panel lights in the dash?
2. Does anything else work when you turn on the ign sw? Relay K02 energizing should power wipers, horn, heater blower, transmission controller(display on, showing N N)... None of that works?
One of the first things I mentioned was that electrical power/voltage is not considered good until it tests good under load. measure voltage at the X1 24V and X3 GND test points on the left side of the power panel(round metal discs with a threaded hole). Got 24V? if so continue measuring it and turn on the ign switch. Still got 24V? A really bad electrical connection will still pass full voltage throughout the circuit UNTIL you try and pull some current thru it by connecting it to an electrical load. the resistance of the connection drops all the voltage...
If you still have 24V at X1 with the sw on, Relay k02 pin 30-87 connects that 24V X1, with a series of circuit breakers/fuses to power all the things I just mentioned. Its the whole bottom half of the electrical diagram i posted near the beginning of this discussion. Look for voltage to and thru CB77 and 79. Pull them both out and install comparable sized standard automotive blade fuses. Those have little bare metal test points on top that allow you to measure voltage on both sides of the fuse. Those two CB's power the idiot light panel and the trans controller. If you are not getting power to these CB's, either K02 is not passing it when energized, or there is something with the wiring on the under-side of the power panel. You can bypass relay K02 using a jumper between pin 30 and 87 in the K02 relay socket. Standard male 1/4" spade terminal lugs and some wire can make a test jumper to test this.
we don’t have any LMTVs though…
