Once I got bike running this evening, tested battery again. 12.91 across terminals. Rev the bike up, and it goes to almost over 17 volts . I know somebody mentioned last week that that voltage would blow bulbs etc. but it hasn’t done so yet.
I went into diagnostics mode then and when I break about 3000 rpm, it jumps straight to 18volts. The battery light is flashing and the speedometer lights start to flicker.
Is this the voltage regulator?. Is it Hard to replace?. For sportsman 400.. 2005
Does this point to any other issue?
Thanks
