Hei 4 pin module

There are three basic types of HEI control modules , the four- pin , five- pin , and seven- pin modules. The four- pin module was used on conventional carbureted engines and uses conventional mechanical timing controls (vacuum and centrifugal advance mechanisms). The ignition module is extremely accurate in its delivery of energy resulting in more accurate ignition timing.

For even more performance upgrade to the heat digital . I lost spark in the old Chevelle last week.

I am pretty sure the module went bad.

I had this one laying around and decided to bench test it and why not put it on .

HEI distributor test - Duration: 3:43. The modules can be broken down into several classes characterized by the number of pins they have and the labeling of the pins: - pin . FREE DELIVERY possible on eligible purchases. This high performance HEI module provides your plugs with more spark over the stock module. The solid state electronics provide high coil out put and superior reliability.

The Dwell control circuit ensures, long consistent coil charging. The current control circuit protects against coil over heating. PerTronix performance ignition modules are direct replacements for popular GM and Ford electronic distributors.

Peak current level is reached just prior to spark for maximum energy without the heat build-up, increasing coil performance and module . Works with non-computer controlled ( - Pin ) HEI housings. The Dyna- Module has more electronic dwell in it to provide more coil saturation time. The lost art of servicing GM HEI. Adjust the rev limiter without removing the cap! HEI Ignition Tips for Your Engine - Duration: 7:32.

Make sure to use the DR1type modules , or one from the same family as described in the HEI module notes. Click on the link below for notes on the GM modules and notes on . Our performance ignition modules are direct replacements for popular GM and Ford computer controlled distributors. These modules provide enhanced high RPM performance and when used with their corresponding Flame-Thrower coil, increase spark plug voltage by more than . We can already hear the Mopar guys.
