Distributor cap spark erosion relative life - brass vs aluminum
Distributor cap spark erosion relative life - brass vs aluminum
(OP)
Happy new year !
So I saved 5 bux and bought an A*t*z*n* aftermarket distributor cap for a 5 cylinder Volvo.
The one I took off was Bosch with brass contacts with plenty of erosion and fine dark metal spray extending a ways in either direction from the brass terminal. I'm thinking it might have even been original 1996. The brass rotor tip was a bit charred as well.
This aftermarket cap has aluminum terminals. (Reports are, some have brass terminals)
Realistically, what is the difference in life between brass and aluminum in this service ?
thanks,
Dan T

I don't expect to be peering into that distributor cap's nether regions for a few years, but here is a manufacturer who apparently is willing to state the contact material -

No correlation found between terminal material and erosion/life.

I am tempted to remove the new cap just to implement that greasy suggestion/recollection. Towards the end that car was demonstrating a tendency toward hydrophobia, but that I believe was aggravated by an oily dirty mess in the general vicinity, held captive by a well intentioned cover nearly integral with the cap.

DO NOT use just any old grease inside a distributor cap. Use only SILICONE grease.
The reason is simple.
Under stress, hydrocarbon grease decomposes to carbon, which is conductive, and will cause problems in a distributor.
Under stress, silicone grease decomposes to fine white sand, which does not bother the electrical components of a distributor.
