This is all facing the back of ign switch.. Switch PN Is 4KA and do not know year of it..
Her e is how back of switch looks 1-5 are hooked up via plastic item from wiring harness, 6 is open to plug on and told that is “traditionally a ground” a universal ground or for lights I do not know.
1
2 3
3 5
6
The yellow safety wire goes in NR 1 and continuity checks shows it a ground.. which I guess goes open when on seat, out of gear etc..
Nr 2 is unk, nr 3 is a black wire, nr 4 red wire, and 5 is unk, 6 I think is a ground (green) for headlight as 6 and 1 have continuity on switch.
Wire harness is a red/green for lights (not used now) a yellow that is to safety switch and one goes to coil to ground it which I suppose is safety deal. I am left with two black wires... neither of which show to ground on continuity check. A white wire (combo with a black that I think goes to charge or such, have not opened up cower under to trace them yet.. A red wire that runs to starter sol..
So I have 2 black unknown (but maybe couple up at one terminal?)
1 white that goes to ground and goes with black.. suspect it is for charging
1 red that goes to starter sol. Also has bat red and a black ground (two prongs there) and yellow at sol..
1 yellow wire that either hooks to 1 or 6 on switch.
NO OTHER WIRES, no orange or such. Eng is brigs twin.. 46 inch older murray.
So IDEAS on wiring up switch? PN on switch appears to be 4KA on front and has Pat Nr of 3497644
