Ok guys, I’ve been sorting the wiring out and am stuck with these six, 

think they are to do with the test switch, is there anyway I can connect up to a normal 2 pole flick switch and also which go to which

is the single red one direct to battery positive??

Any help much appreciated

Stared at this too long.

I think the red wire in the connector was fed from a 25 amp fuse.

The test switch has to be a double pole double throw momentary switch.

The black with blue strip might be the one going to the low oil circuit from the test switch along with the 4 taped together.

 

Something we have learned is the complete light panel can be disconnected and it will have no effect on the rest of the tractor.

 

On the last picture what it the switch behind the loose wires for? Headlamps?

Yeah the switch is the head light switch 

so should be ok to leave the wires taped up and not connect the test switch 

thanks

So you think the red wire should be connected to battery positive with inline fuse? 

Thanks

:text-yeahthat:     The wiring on the 310-8 is the same with the exception of not having those test lights, less useless parts to fail!

Looking at the diagram that red wire only feeds the indicator lights that no longer work so no need to hook it up either.
