Hi,
From the 2000 ST4 wiring diagram kindly provided by Derek I see that there is an "Electric Fan Relay", number 10 in the diagram which is connected to the 7.5A fuse under the seat.

This relay is in addition to the two relays under the seat that control the fuel pump and cooling fans which are connected to the 20 A and 5 A fuses respectively.
Where is this Electric Fan Relay (identified as number 10) physically located on the bike?
My cooling fan does not come on as intended, but strangely, as the ignition is turned on, the fan runs for about 1/2 a second, almost like a relay contact is bouncing. I have replaced one of the under seat relays and then swapped them around and the fuel pump runs either way. All the fuses have been checked, but just can't find the other relay.
Before jumping into a fan relay bypass mod, I would like to get the system working as designed.
Thanks in advance,
Richard
