I just replace the three big electrical parts to my F3(R/R, Stator, & Battery). Prior to me doing that I am thinking that my battery sent a power surge through my system and blew my headlight and tach. I checked the fuses and replaced the blown ones, I also replaced the bulb in my headlight which is working fine now but my tach still isn't working at all. All my other gauges work it is just my tach. Any suggestions?

 

On my CBR600F1 Hurricane when it was hurling the VR/R besides the bike running like crap before the unit died the tach jumped around like crazy so you just might be right about getting a surge and frying your electronics...

I have a F3 speedo with 400 miles on it if you need a speedo?
