Rated 5 out of 5 by from Water proofNeeded a replacement on my commercial mower. Last two failed due to water contamination. Looking forward to finishing this year with no more problems.

Rated 5 out of 5 by from Used for high amperage cooling fanI'm using two of these relays in my Jeep. It is powering a notoriously power thirsty Taurus fan. This fan is known to pull upwards of 35a, if not more, when flipped to high speed from a dead stop. I've ran the fan on both a low and high speeds for extended periods of time with no heat output by the 70a relays and its big power terminals. 70 amps may be a bit overkill, but better safe than sorry. Get some nice juicy wire, fusible link, a couple of these puppies, and you have a solid electric cooling fan conversion.

Rated 5 out of 5 by from .375" female connectors are available locally!At any autozone or oriellies auto parts store. This is a high capacity relay, thus the .375" terminals. The .25" connectors on other relays are not capable of handling the 70 amp load.

Rated 4 out of 5 by from Need to order 0.375" terminalsAs seen in the other review, you need larger terminals to connect to the contacts. Here are the Newark P/N's:30M9211 (socket)95C1520 (terminal)

Rated 4 out of 5 by from Caution !!!This unit is a great value, like many of the items on the site, but the picture is not accurate. Two of the contacts require .375 in female quick disconnects which are extremely difficult to find. I'll probably try the 50amp relay for my project.
