Relay Delay Module

Relay Delay Module

Relay Delay Module

Your dual cooling fan system works much better than the single OEM fan. But, doubling the relay load tends to overload the OEM relay (which is designed to run one fan only) so you most likely use one of our dual relay fan conversion harnesses. But, in certain applications, turning on both fans at once causes a “sag” in the electrical system, leading to engine stumble, shutoff, or worse. These applications can be remedied by using our Relay Delay Module. This module is required when using two cooling fans on your GN. Attaches to one of the fan relays, this module will delay that fan for about 5 seconds, assuring a more linear startup load to the electrical system. Designed to attach to a fan relay only (not to the fan motor). Simple, two wire installation.
