Would appreciate any help finding out why speedo and tach both quit last year. Have tried tracing wiring diaghrams and such helpfull info but still no luck, Car is 93 R-1 track only toy that I play with at DE's here in the SE.

 

Odometer out as well? Are you getting a tach or speedo reading on your PFC commander (if you have one)?

 

What have you done?
What tests and checks have you performed?
What pages in the wiring diagram have you referenced?

We need more details.

 

Sent mine to hamp speedometer to get fixed. works perfect now
