Bendix Tachometer manual
 

Hi Everyone,
I have an issue with the Bendix Scintilla dual tachometer part#C668010. The front engine pointer is fine but the rear engine pointer is dead. I've read previous messages about possible causes and tried everything so now the issue is the tachometer part. The avionics shop tech can possibly repair mine if he has access to the service manual. If anyone has a copy and possibly send it to me I would be very grateful.
Cheers!
Tim
