Tach dying randomly.
 

so this is a new problem. sometimes if i quickly peg redline in nuetral the tach dies. then once i restart the car, the tach works again. suggestions as to what i should look for to fix this? its kinda annoying.

Every FC I have ever worked on has had this. Not rev up but just die. Restart the car and work again.

So far my guess is the cluster b/c I have swapped T coils.

a lot of times my tach doesnt work at all, but only on really cold days...hehe

actually it has only done it while it was cold....

when my tach died erratically like that, I replaced the 7.5amp meter fuse and never again have I had a problem...

I always assumed it was the harness connector or PCB solder connections.
Every time I go to test it, it's working, and I can't get it to fail.

The fuse.. Cool.
