748-916 fuel pump relay woes.
So...........................i have a 1998 748 with a 1998 916 Motor with a 916 eprom.
When i go to start the bike and turn the key i get the pump kicking in as it should via some ''action'' , clacking and the like from relay #2.
The bike will start and run fine. the problem beings after ive turned it off and want to turn it on again
l can turn of the bike and on again and it will be fine as long as i do this under around 10 seconds, if i wait longer than that i will get a clack from relay #1 and the pump will not engage when the key is turned on.
lf i then swap the relays over the pump will kick in fine
lf i then take out the relays and put them back in the same place pump will not work
lf i then just take relay 1 out and swap it with another spare it will work
lf i disconnect and reconnect the battery the pump will work
Scenario repeats itself if you use the kill switch instead of the key
l have tried this with 4 relays, 2 old 2 new, mixed all ways, this scenario repeats itself over and over
lts like the first relay is getting a signal it shouldnt..........................i fuggin hate electrickery
Pleeeeeeeeeeeeeeeeease help, as a gallon of petrol and a lighter is beginning to make me feel warm and fuzzy all over
