Guys I have switch 73 check right ramp not working. I replaced the optos and did not fix the problem. I thought that was the problem. See J206/207 connector. Not sure the wires are in the connector in the right order? J206 causes PF exit to error out as well on top of right ramp error 73.

Looking for an answer....... Where do i start with check right ramp 73..... I messed with one of the optos before replacing and it worked fine for a while and now that I am trying to sell it the optos don't read the ball going into mini PF. Kills the whole game and the only error code on this.
Quoted from Coyote:Well, in switch test, does the opto show open or closed?
If closed, when you wave your hand between the sensor, does it switch at all?
If it's open, then the opto (or receiver) is not getting it's power/signal from the Opto Driver board. Could be a broken wire, bad crimp on the pligs on the opto board, or a bad LM339 on the opto board. (Or, the opto could just be dead.)
If it's closed, and it opens when you wave your hand through it, then.. well, it's working.
Not sure if open or closed, if the square is already there or not. When waiving my fingers thru it does nothing. Square comes and disappears on Power PF exit. Quickly looked at Opto board under PF and I suspect something there. J2 was labeled and resistor on the board looked like it had been soldered on. Will take it off tomorrow for a more thorough inspection.
