I've had 1 pertronix unit fail and that was my fault. I hooked the wires up backwards .

I called the tech line and told them what happened and they warrantied it for me even though it was my fault.

This was back in the 90s.. ive installed many units and have never worried about it.

I did keep a set of points and a ballast resistor in the glove box just incase.

As for todays points and condensers.. the cheap is cheap for a reason.

I went through many brands and many prices to finally get a set that would last and run decent.
Nothing is more pleasant than doing a 10 minute job 5 or 6 times because the parts sold today are made over seas
