Tachometer needle bounces and lights don't work

From our experience, overheated wires are usually related to a problem with a ground.

Thanks i'm going to check my grounds engine one is good the little one on the flywheel housing will get a sanding and a coat of dielectric grease too. I hope I don't freeze tomorrow wind chill advisory in the am!!!!

Tach runs off the voltage from the motor, which of course is why grounds are so critical. If the voltage regulator is toast, your tach will go crazy, and you will blow out bulbs. The smaller bulbs will blow first.  Might be wothwhile to take a look at the regulator.

Yes the tach is bouncing a lot and both the tach and speedo bulbs were blown but the head and tail lites were good.

I'm going to pick up a voltage regulator and replace that. Thanks!

Thanks got my lites working the "two yellow wire connector in the "to the stator plug "wasn't connected due to it being melted I just by passed it to the single wire "coil" with a male spade connector lites work great now but my tach is goofy I'll look into that brake lite sticks too I'll fix that too. Maybe I need a new regulator to fix the tach? It did work for a while on my ride yesterday. My buddies 79 el tigre 6000 blew a radiator hose! Second time I've had to rescue a dead kitty off the trail lol.
