Hi could some one with the knowledge help me to correctly wire the on off switch please. Battery Connector 1 has a the positive red wire connected to a terminal post this leaves the black negative lead of battery connector 1 to connect to the switch..
Battery Connector 2 has the black wire connected to the terminal post leaving the positive red wire to connect to the switch. Next bit is I am left with 3 additional wires to connect to the on off switch coloured orange , blue and red. there is a yellow wire which looks like the manufacturer has not used it for anything. Thanks...any help appreciated..

I have tested all the chips and all are fine but this old fisher refuses to work for unknown reasons , got me baffled this one. hate to have to scrap it but it's looking like the end of the road for it....
mostly op amp chips and a few transistor array chips all tested perfect , no rocket science here. looks like it just wants to stay dead ! wondering maybe a bad coil or bad wiring some where I missed..
