Yes there was a fix at this point. Techdude2000 from GL1800 forums (who is know as the GL1800 DR) said that the wiring and C25 connector could be the blame. He said it’s common that the C25 connector over time causes problems. Because the wing was constantly stalling and had 1 over heating issues because the fans didn’t kick on, made him believe it was an electrical problem. After examining, cleaning, disconnecting/reconnecting the C25 connector, checking for loose wires and the entire harness, I must have triggered something. I let it idle for 1 hr and took 2 20 mile trips with it and had zero problems and the fans kicked on when they needed too. I recently took a trip that was over 7 hours, over 350 miles with my fiancé, in 85 degree weather, with stop and go traffic, and the wing had no problems. So at this point it is fixed. It surely would have shown it’s ugly face after all that. Techdude said if it comes back that the problem is obvious, it’s the sensor loop down the engine or the C25 connector will need to be “re-done”. So to answer your question she is up and running, whether I fixed it permanently or by “accident”. :)
Hey DB & Techdude I'm just wondering if this is the issue i'm having with my 2004 1800 Goldwing when I take the bike for ride and get it warmed up the temperature gauge rises almost to the H when I stop or idling and then when I take off to ride the gauge would come back down to normal and stay normal till I stop again and this all started happening after I had gotten stuck in stop and go traffic for over a hour that's when this 1st started happening and now it does it every time I ride the bike. The fans do come on but it still stays in the high range when idling till I take off from the stop any suggestions appreciated

This sounds like a coolant issue. When the fans come on, the temp should go down, since it’s not there’s a flow issue, possibly a stuck thermostat. Are the fans blowing out the front from both sides?

Hey Techdude thanks for responding sorry I didn't get back right away, fans do turn on I guess I could check the thermostat are those known for going bad as this all happened last year I just took bike out today and fans came on and bike didn't get up to total hot so I'm going to have to ride it a bit more and pay attention what its doing

Thermostats don’t go bad very often, but with your symptoms, if the coolant level is correct and the recovery tank has the correct level in it, then that only leaves a blockage or the thermostat. When was the coolant changed last and has it ever had the system and cap pressure tested?

The coolant was changed 2 years ago levels are all correct but never had the system or cap pressure tested. I guess I could change out coolant again to see if this helps

Ok, so if you let it just sit and idle the temp keeps going up? I would flush and change the coolant, it’s due anyway at 24 months and see what it does. Make sure the cross connect between the left and right sides is clear along with the drain.

Hey Tech dude sorry I haven't responded I've been really busy with work and not even time to look at the bike when I finally get a chance I'll try changing the coolant out and see if this fixes my issue. Thanks

Hey Dog - Just to eliminate a possible issue - Have you tried resetting your ECM computer ? Start your bike giving it no throttle, let it run until the fans come on then trun off the engine. When you are riding, if there is no "FI Light" to help you with some self diagnostics and the problem persists, the next option may well be to have the dealer run a diagnostic sweep of your bike. On the newer models just about everything (including fan control logic) goes into and out of the computer. There have been a few 1800 GW's with a similar reported intermitment stalling problem that turned out to be the ECM.

Hopefully it turns out to be something simple.

Good Luck - Michael
