Default MSD Fan loom Fuse rating?

Hi All,

Just a quick one. What's the rating of the fuse's for the relays on the MSD fan rewire looms? The original one's are rated at 15amp, however speaking to MSD i'm told they should be 25amp? I've never changed the fuse until it decided to melt on me after 2 years use. (Relay has corroded). After a few seconds use the relay was getting super hot. Changed it over from my fuel pump relay and it's staying cool.

Also where's the best place to get good quality relays from?

No matey, they are both free and spin by hand so there's not much resistance.

The relay itself seems to have corroded internally. If I swap them over for another relay, with the fans on the new relay stays cool.

Just curious to know the fuse rating
