AMI J120  the 1960 one

Pulse converter

Can someone help I have a problem with the wires they have all, but one come adrift from the 6 pin connector that connects to the back of the pulse converter



Have a pdf circuit only. But the wiring diagram for this part is unreadable.

Anyone know were the wires go?
They appear to be original colors

Or can anyone supply a readable copy of this section?



Thanks
New boy

Hi Victor,
My J manual is a photocopy and also not very readable but you should be able to figure where that wire goes by a process of elimination. There are six pins and nine wires - pins 1, 2 & 5 have one wire and pins 3, 4 & 6 have two wires connected.

Thanks for the reply but without knowing which color wire goes to which pin. Have started to track were the pins goe inside the converter. Now using the circuit just have to test for AC and DC volts and find which is the signal and select inputs, I think.
