I tested both switches in a pan of boiling water with an ohm meter attached, and followed directions from the manual, both failed the test. I only took the bike for a short test drive because it was running so bad, but I do know that the temp. gauge didn't work at all, as far as the fan goes I don't remember if it came on , but I did test the fan and it works ok. Unless I did the test incorrectly I'am not taking any chances and replaced both switches.What is the 7V reguator?
Thanks for the info.
The 7v regulator supplies power to just the gas gauge and the temp gauge. It's in the back of the gauge cluster. If they die, you can get used or even make your own from radioshack parts. If your gauges are erratic, sometimes it's just a bad connection there. Does your gas gauge work? Do you have a schematic?
Here is one: http://www.aspectcomputing.com/downloads/Honda 1100/
7v goes to both gauges, and the ground for each is a sensor/switch. If the temp gauge doesn't work at all, I would try to ground the temp switch and see if the gauge goes full scale. If it doesn't, you would have to look for a broken wire and/or replace the gauge.
I just got spare a fan switch still in the housing for my 1200.
I haven't tested it yet,but, I did remove the switch from the housing to clean it & test it later; The only sealer is the o-ring..no sign of sealer on the threads. I'm thinking the switch needs to ground to the body/housing to work properly. Applying sealer to the threads may inhibit this function...that's MY story and I'm sticking to it!....LOL
