Has anyone seen a resistor installed in the D2 location on a Party Zone MPU. I have just noticed it and have not seen this before.

I have not.
That is a strange factory stuffing error.
It should be a 1N4148 of course.

If at the end of that yellow wire is a rechargeable battery, then it is done for that reason

That is what I thought although wanted to check in case there was a reason for it. Will install a 1N4148 to return it to spec.

I did think that maybe a reason, in this case the yellow wire goes to an external AA battery holder. It had non rechargeable batteries installed. Maybe it had rechargeable batteries at some stage although not sure. I will just return the board back to spec.
