Relay switch

I have a 28!model A with a stock 350. I keep burning out relays. The fan is a new puller located between the radiator and the engine. The fan kicks on a 190 degrees and the engine normally runs at around 200. I see some burn issues at the plug located under the dash at the fuse box. I have a separate switch for the fan which I keep turned off. Any ideas.

Re: Relay switch

The fan kicks on at 190 and the engine runs at 200? First fix that the fan should not be running when the car is cruising.

Also what car do you have and what year?

1928 And It’s Just Broken In

Pertaining to your 1928 model A Ford, too much resistance at the socket contacts.

The reason(s) is/are the contacts are dirty, the socket is of cheap construction and the contacts were made from too thin metal.

If the latter, upgrade to at least a 70 amp relay and socket.


Happy Racing !
