Nick, Back in the day I would service school clock systems. They were impulse systems, once a minute the relay could close for 3 seconds (that is 1440 times a day). They were 24 VDC with high amp draw. When a contact opens you will get a small arch across the contacts, doing harm to them. Now the rest of the story... Let's think about your old original distributor. In there you had points (contacts) and a CONDENCER. The job of the condenser was to absorb some of the arch that would want to jump across the points (contacts) keeping them from burning up. In the schools I would install a condenser and resistor(bleeds off the power in the capacitor)to save the contacts. What you need to do is buy a bigger better really. But now you know why...

I replaced one and a year later its bad again. Nick 7252
