The temperature gauge on my V65 stopped working. It had not worked for about a month. Then it came on one day and stopped the next.
It displayed properly at powerup. It just would not show a temperature. All boxes were blank. I tried shorting it to ground. According to the Honda book the gauge should show full hot. It did not show any boxes.
I checked the sender and it was working.
So I took the front apart and was getting ready to replace it and thought what the heck. I grabbed a can of contact cleaner and sprayed away. I pulled all three plugs on the guage. I pulled the lead off the sender and sprayed it. I noticed that the lead was a little loose so I squeezed it and put it back. It is tighter now.
The temperature gauge works again. So I must have had some gunked or loose contacts.
