Distribitor Cap problems

I have noticed that the new Dist Cap and rotor are burning at the contact points inside and is not getting enought power, I just installed this cap and rotor about 2 weeks ago, I sanded the contacts and it runs better. What could be doing this?

thanks

Possibly bad wires, plug gaps too wide...

GOod guess but New Wires. plugs .035 gap and downsized them from .040 to see if that helped.

Wells cap and rotor? Utter crap.

I am not sure if it a Wells or not, I got it from advance auto parts and I do know about Wells being crap I ran into some bad E modules once and they were wells

could be moisture in the cap.. take it off, spray it with ether, let it dry, than put it back on..

Might work..
