When you say connect the yellow/red do you mean disconnect them from the gear shifter and connect them to each other before they enter the switch? We tried that yesterday and got a small click, them the gauges went to flatline.Great.
Here is what those wires do.
At the throttle, the two yellow/red wire are for the start in gear. If you want to bypass this switch, disconnect both of them and connect the the ones that DON"T go to the handle to each other.
The red is power to the trim switch, when you move the switch up is gets connected to the blue wire, when you move the switch down the red gets connected to green wire. Just remember the sky is blue and grass is green.
At the key switch,
Black is ground from engine
Red is power from engine
Black/yellow gets connected to the black to stop engine when key is off
Purple gets connected to red when key is in the on position
Yellow/red gets power from red when key is turned to start (this is the yellow/red you jumped to red back at the starter solenoid to get it to crank over)
Yellow/black get connected to red when you push the key in to choke the engine.
What I don't understand is that when you connected the black and red together, this should have been a dead short and melted the fuse on the engine.
Is this enough info for you to figure this out, or would you like me to try and walk you thru testing with the voltmeter?
Something to remember about these older 2 strokes. The engine doesn't need power to run. It needs the black/yellow to be grounded to stop.
You should never move the shifter unless the engine is running or you're turning the prop by hand.The gear shifter can feel really hard to move at times and then it seems easy. Also, the button to push at base of gear box to put in neutral...I took the cover off and the button itself cannot come out but it does not seem to do anything but easily slide back and forth. I'm not sure what that is supposed to do.
The gauges flat lining probably means you have a bad connection or wire in the system. That should have made it crank.When you say connect the yellow/red do you mean disconnect them from the gear shifter and connect them to each other before they enter the switch?

I mean the two wires that DON"T go to the shifter. One of them will go to the key switch and the other will go back to the motor. The yellow/red wires coming out of the shifter usually have a quick disconnect somewhere in them.When you say connect the yellow/red do you mean disconnect them from the gear shifter and connect them to each other before they enter the switch?

Ya, red to black at the key switch sure should have let the smoke out of the fuse. Not sure why it didn't, maybe has very high resistance somewhere. Still that doesn't explain the chirping.Careful if you start connecting wires.----Smoke can be expensive.

Then someone has already bypassed the in gear switch in the control.The yellow /red that goes to ignition goes all the way to the motor.
Can't see what Jeff J said.What Yellow/red should it be connected to?
To the S terminal on key switch and one of the small posts on the starter solenoid.What Yellow/red should it be connected to?
Look at post #17Can't see what Jeff J said.
What do u mean by both sides of the plug? And main harness is what?I had a 90 about that vintage. It acted similar. The main harness connection was the problem on mine. The contacts were corroded. Disconnecting and reconnecting the harness would make it work for a while. I tried to clean it a couple of times but it needed new contacts on both sides of the plug.
