Review on πŸ”₯ Mallory Ignition 605 Unilite Ignition Module (Thermalclad): Enhanced Performance and Superior Heat Dissipation for Optimal Ignition by Carlos Macy

Revainrating 1 out of 5

Mallory joins the bad list

My first Mallory module drove about 100 miles before it gave up the ghost. This time I'll try a new one with a built-in mains filter. I find it amazing that Mallory would sell an expensive product that is not subject to voltage spikes when the product IS PART OF A SYSTEM (DEALER) WHOSE PURPOSE IS TO GENERATE VOLTAGE SPIKES. Someone else suggested replacing it with a Pertronix device - trust me. - Avoid the plague as their rotors form invisible cracks that shorten the high voltage ignition pulses through the rotor to the distributor shaft. If anyone else has a suggestion for replacing the Rover V8 ignition system, please suggest it. The options I know of are (1) original Lucas gear (low quality and very expensive), (2) Pertronix crap, or (3) Mallory - used to be a great American company now I can't remember what . I think at least Mallory was kind enough to post a video explaining how to diagnose a fault if (rather when) your Mallory module fails. The video was helpful and can be found on Youtube. All you need is a voltmeter.
