Fan

[B.Bolding]

Som years ago the fan quit working so I hooked it to a switch to turn on and off manualy. I am going to replace the timeing belts and thought I would try to fix the fan being I will have the radiator out anyway, is the relay and or related parts still available to fix these fans? Thanks in advance Brian

Brian,

The fan runs when ground is applied through the thermal switch at the radiator. You can pull the lead off of the switch and short the two wires together with a jumper to see if the fan comes on. If it does then you know your switch is good. If not they are still available through Honda, eBay or OEM parts places.

There is no relay for the fan, there are some that feel there should be.

Fused current goes to the fan, then from the fan to the fan thermo switch, then from the fan thermo switch to ground.

When your rad is out you can remove the fan switch actually you dont need to remove the rad as you can get to the thermo switch without.

Pull the plug from the fan switch, jumper the contacts on the plug, switch the ignition on (in your case make sure your add on switch is in the ON position)

The fan should work. If not then it is in the wiring, if it does it is probably the fan thermo switch.

If you want to go OEM you can get the original, there is a post about using an after market switch, now this is for an 1100 but I think it would be the same for the 1200 <!-- m --><a class="postlink" href="http://www.goldwingfacts.com/forums/forum9/38226.html">http://www.goldwingfacts.com/forums/forum9/38226.html</a><!-- m -->

Remove your fan thermo switch, suspend it in coolant and using an ohm meter connected to the two pins,
The switch should have continuity (closed) at 98-102°C (208-216F).

Thanks guys for the input. :-bd

Some one posted the thermo switch worked on the ground side instead of the power side. Power supply-fan-thermo switch-ground.

Poorboy

Yes your right...... brain fart Green goes to ground

I edited the original post, so as not to create confusion, I dont know why I said that, I have looked at that and worked in that area for years...

Good job your keeping an eye on me Poorboy

Depends on if you subscribe to the conventional theory or the electron theory.

Either way works.

Electronics teachers and authors of textbooks are often chided for passing on an "error" to their students. Teachers promote idea that electric current is a flow of positive particles in one direction, when supposedly it's a flow of negative electrons going the other way.

In fact, the teachers are right and the chiders are wrong. The chiders labor under the misconception that "electricity" is invariably made of negatively-charged particles called electrons. This error also leads people to wrongly imagine that electric currents are always a flow of negative particles. Actually, in some situations electric currents can really be a flow of positive particles. In other situations the flows are negative particles. And sometimes they're both positive and negative flowing at once, but in opposite directions. The true direction of the flowing particles depends on the type of conductor.

WOW... DID I ever waste a lot of money at college... The area that is wrong is in our labeling of power sources... The terminal that we call the positive terminal actually is the one with the most negative charge (electrons)... The terminal was named "positive" because it was the source of the current flow... Back in the very old days many folks didn't know much about electrical flow... They just knew the energy (electrons) started at this point (positive terminal) and ended at this other point (negative terminal)... They did not care about the fact that an electron carries a negative charge or not... They just viewed it as particles flowing from here to there view point (positive to negative)...

That is a good article written by William Beaty: <!-- m --><a class="postlink" href="http://www.eskimo.com/~billb/amateur/elecdir.html">http://www.eskimo.com/~billb/amateur/elecdir.html</a><!-- m -->

He goes on to say:

"Batteries are another example of non-electron or "ionic" conductors. When you connect a lightbulb to a battery, you form a complete circuit, and the path of the flowing charge is through the inside of the battery, as well as through the light bulb filament. Battery electrolyte is very conductive. Down inside the battery, within the wet chemicals between the plates, the amperes of flashlight current appears as a flow of both positive and negative atoms. There is a powerful flow of electric charge going through the battery, yet no individual electrons flow through the battery at all. So, while the current is between the two plates of the battery, what's its real direction? Not right to left, not left to right, but in both directions at once. About half of the charge-flow is composed of positive atoms, and the remaining portion is composed of negative atoms flowing backwards. Outside the battery in the metal wires the real particle flow is only from negative to positive. But inside the battery's wet electrolyte, the charge-flow goes in two opposite directions at the same time. (And if we built our circuit from hoses full of salt water, then all the current would be bi-directional.) "

Actually, the author was making the point that we should just measure current in amperes and forget about the current flow because it is much too complicated when trying to teach the subject in a basic electronics class.

Think of the positive pole like a vacuum cleaner sucking the current from the ground. :lol:

Hmmm..in a negative ground system, wouldn't the negative be the ground? Hmmmmm...
I wonder why they call it a negative ground system?
Probably based it on electron flow :roll:

Sorry guys ,I did not mean to start battle of the minds :!: :!: :!: :!: :lol: :lol: =)) Thanks for the help.
