    VFR800 03 many electrical issues

    Thanks for the advice on the Stator R/R, I'll see what I can do about it. I got the fan problem figured out. If I could at least ride with a tachometer that would be great. Here's the bike.

    VFR800 03 many electrical issues

    Hi, I just bought a VFR800 2003 about a month ago and everything was going just fine until many electrical issues showed up. The first one that I noticed was the Clock and trip odometer would reset back to 0 almost everytime I would start the bike (but not always). Also, when parked in the sun for a while, the multipanel display would be completely blank until I start moving, then with the wind cooling it down, it would just come back after like 1min of driving and everything would be fine. I went for a long ride on a sunny 40 Celcius (over 100 Fahrenheit) day, driving on country roads, the oil temp would be just fine, but when I stopped at a red light, the bike started overheating and the oil temp was going up like crazy. I found the ''overheating'' very odd since the fan was on and the airflow wasn't bad so I just decided to keep riding monitoring the oil temp to see how it would react. The temperature was jumping by an increment of like 15 degrees (Celsius) passing from overheating at 128 for example, to normal at 100. I did some troubleshooting on this matter latter and found out that the thermostat was functioning just fine, opening around 80 degrees and cooling the bike off maintaining the temperature around the high 80s and low 90s. I did a complete flush of the cooling system and made sure there was no air in the system. When checking the radiator fan with a multi-meter, I created a spark and then I was getting 0 volt my eyes off of the gauge). The oil temperature was reacting just fine going up and down 1 or 2 degrees at a time, and then out of nowhere, it started ''overheating'' again going up by 15degrees and coming back to normal every now and then. Lastly, my tachometer started jumping on the highway on that same ride dropping and catching up for a while and then going to 0 for sometimes. The problem was intermittent and it would work every now and then and don't some other times. Now it's mostly either working for a couple of seconds when the bike is cold or not working at all after a minute or two. I absolutely hate troubleshooting intermitting electrical issues and I was wondering if all of these symptoms would be related to one common issue? Thanks in advance, the bike is running just fine, it's just so frustrating driving with faulty gauges.
