Went to fire up my 3720 today and the tach did its normal full sweep but only part way returned. The tip of the needle appears to be contacting the face of the tach at the top. Looks like the face top has warped outward.
Has anyone ever had this happen?
Can the cluster be opened?
If I have to replace it is it just a swap out? Or will it need programing?

I can only help with the last question. After replacement It definitely needs to be setup by the dealer for it to communicate with the other computer modules.

Thanks, that's kind of what I was afraid of.

I think an hour of shop time would do it. They would probably even make a house call.

Can I bring my 3520 over to Kenny's shop and have you clean it up too, Dave???

I'll even bring ribs and charcoal. I'm sure I could twist Kenny's arm to let me use his Egg!

I think I would just curl up on that nice heated tile floor with the dog, and not get any work done
