What is the end of the wire that goes from the relay to the little bracket above the crank supposed to look like? Mine looks like a bunch of shredded copper wire. Oh, my tach doesn't work.

Thanks

Excuses are crutches for the weak

Compare the pic to what you have, this is what it should look like. You may need a new sensor: Select Brand

There is one at the Virginia Beach Pick N Pull right now.

Chances are the bracket that holds the sensor is out of adjustment & the pin in the harmonic balancer has hit the sensor breaking it. There's lots of fine copper wire inside it. When you put in a new sensor, be sure to turn the engine by hand to see if there is clearance between the sensor & pin. Also, make sure the pin is still in the balancer. It may have been dislodged when it hit the sensor. I did this recently while adjusting the a/c belt tension. My pry bar accidently hit the tach sensor bracket bending it down. When I cranked the engine sparks flew off the bracket from the pin hitting it. Needless to say the sensor was trashed, with lots of fine copper wire hanging out. A trip to the pick & pull had it fixed after bending the bracket back where it belonged.
