@rsymons posted:the issue seems to be with the molex 4 pin connector to the cruise commander m j3 connector red is supposed to be power/black ground,but when they are connected i get the short. the red goes to the power ,the black i placed to chasis ground. the other 2 wires are for the motor(blue /yellow) according to the diagram pin 1 ac input track common,(black) pin 2 ac input track hot(red)
Yes, it can be the cruise board. But, you may be getting deceived. If you remove that connector. You may be removing the ground path for power. If it supplied via a pcb trace on the DCDR or that black wire jumper. Which would remove the ground path for power which negates your testing. If you have all the two pin connectors off, Except, the one that only the black wire goes to the DCDR.
Then, it is in fact the DCDR - most likely. One set of the two pins smoke unit. The other set of two pins to AC reg. The most common failure in early engines. I also question. if you swapped one of the two sets of wires going to the motherboard. Although. that may not matter. I'm home and have a similar schematic. It appears that grounding for power s somehow at the DCDR. So, the real test is disconnect the other two like I stated, I'm home and have a similar schematic. Anyway, If you had the wires to the smoke and AC Reg unit to the smoke unit disconnected. Then, as above DCDR!
The engine had odyssey with TMCC? I would replaces with ERR. I think the cruise M. Much, smoother performance.
