The plug that goes to the fan has a blue with a black stripe and a black. The black wire is the same wire as the black on the thermo switch. The blue/black comes from a black wire directly from the ignition switch. There should be a connector on the left side near the steering head with a green, a black, a blue/red and a green blue. If it's an aspencade it will also have a light green/red.

I'm not exactly sure what your asking so if I get it all wrong, I'm sorry.

The only way you can really check the thermo switch is by taking it out of the system, you have to drain the coolant down until it's below the thermostat housing and then remove the switch & test in oil or water to see if there is resistance between the contacts when the oil or water heats up. If there is resistance then the switch is OK.

It sounds to me like somebody has wired in a toggle switch to force the fan to run. Too me that would indicate the thermo switch is bad or switches on at too high a temp. When the bike runs the fan should come on about the middle of the temp gauage if it doesn't I would replace the thermo switch. Lots of folks ( me included have put a 1994 Geo Metro switch ) in place of the Honda thermo switch. They work fine.

There's a couple of ways you can look for the connector.
1.The other end of the connector you are looking for is most likely still there but unplugged. Take the left false tank panel off & the lowers on the left side ( if you picture is the bike we are talking about. Look in the area directly to the left & down from the air breather snout. On my bike its a clear coloured connector.
2. Take the air breather out & look around the area just in back of & left of the coils as you are looking from the seat. Upper area between left false tank housing, coils & carbs is about where this plug should be.

Am I on the right track.

In a normal situation ( fan hooked up normally with no toggle switch.) Unplug the thermo switch plug & cross the contacts on the plug itself with the ignition on. The fan should start.

In your situation, your fan as I understand it,is not connected into the stock wiring so doing the above won't tell you much of anything. Find the connector & plug it back into the stock harness. Then you can try the above. You might have to move the toggle switch from off to on as I would think the toggle switch would have to be off in order for you to use the test method as above.

Aim I getting closer.
