If you check out the MSD stuff you will find a few failures especially the MSD ignition boxes.

From what I have been told by people that run Mallory Unilights you have to be extra careful when welding or jumping off a Unilight equiped engine. Always disconnect the ignition before welding on the car or charging the car. Never jump start a car with a Mallory Ignition. Charge the battery with the cables disconnected. The LEd in a Unilight is very sensitive to power spikes.

Many Unilights are damaged by hooking up wrong or by not using a ballast resistor. If you run a Hyfire box you do not need the ballast resistor.

I have seen many MSD failures and I would not recommend jump starting any modern electronic ignition cars.

I have ran my Mallory Unilight for over two years and many of the miles are under road race conditions. Drove the car from Pensacola to Ocala, Florida in 5 hours and back the next day. Never a hickup.

Take care of it and it will give good service. Maybe MSD has less failures because there is less of them on the road? Mallory has been around a long time and they make OEM ignitions for Boat manufactures.

Don't get me wrong MSD makes good stuff but they are not the only option out there.
