task alfa 250/300 ci engine board question

[n25an]

Does anyone know which wire harness plugs into yc25 on the task alfa 250/300ci... I have asked the help desk and they told me they dont have the parts list so goto the parts warehouse... I called the parts warehouse and was told they are not familiar with that model and will research it... I called up the local kyocera area tech and he couldn't help... the parts manual and the service manual don't give you any clear ideas... help...

YC25 is connected to the eject motor, paper full sensor, fuser motor, fuser clutch and fuser fan motor. It's very hard to tell which harness that you need to order that goes to that connector. Even looking at the machine it's hard to tell trying to match it up to the parts manual. Why do you need that part?

I have a task alfa that keeps telling me that the exit tray is full... I switched out the sensor, the error went from being their fully to intermittently... switched out the exit unit... error went from being there intermittently to 15 minutes and then it was back... switched out the harness... and the error just went away... called customer today and error might be back... so that might mean engine board is next... anyway... I need the harness becuase I swapped these parts out of a kyocera machine at the shop... and I want to get it running again... the only part I am having difficulty with identifying is the harness...

thanks for all your help....

Here's a thought just replace the wiring that you think is faulty from the connector to the board. Shouldn't be that hard with a little bit of motivation. I would run jumper wires and test it. If that works then make it a little more permanent. I have seen guys fix issues like this with old speaker wire. I know its crude, but if it gets your customer up them you both win!

If you can pinout the harness and identify the specific wire, it's really easy to replace individual wires. You don't even have to remove the old one, just clip the ends.

One of the more memorable ones were a main body harness on a Sharp Cougar. I had an open lead to the transport sensor (5vdc lost). I couldn't find the break, but could very easily add one additional 16 gauge lead and splice in the ends. It sure beats stripping out a main body harness.

Now if you cannot identify the bad connection or it's intermittent, that's another story...
