Yamaha 450 EFI 14-Newer Dual Fan Kit for aftermarket wiring harness set up with key on fan on.
Yamaha 450 EFI 14-Newer Dual Fan Kit for aftermarket wiring harness set up with key on fan on. This kit is great for XC dead engine starts, we take the key on fan on power and run it through our coolant line 176 sensor and run the second fan with a second power source wired directly to the battery with a 200 degree sensor. This allows for a dead engine start with maybe no fan running depending on how hot you got your coolant or at least only one small fan running for faster dead engine starting. Fans have 2 separate power sources. 684 combined CFM
