I changed to a HEI distributor and my old tach,made for point ignition died when i first reved up to 5000 rpm. I think too much voltage on the pickup wire. Now i´ve bought an original Monte Tach from 1973. How can i hook it up without destroying it again?[img:f13fcba882]http://www.2carpros.com/forum/automotive_pictures/333646_1345_1.jpg[/img:f13fcba882]

Did you have old Tach hooked up to the tach terminal on the HEI?

Taht is correct the tach reads each time coil is grounded no power goes from dist to tach that is supplied from cars elect system. Maybe old tach bit the dust
