Good day together, after my Fat Boy only confessed for health reasons, now the HU became due. Battery was dead. So, new battery pure (current condition: 14,4 V, 0,84 A ), new battery in the FOB, but uses everything nothing, sounds somehow as if the injection pump did not get any juice and did not release the fuel (over 10 liters in the tank – NEW ). Air filter lid removed and start pilot sprayed in the air filter during the start attempt, so that Is it possible to deactivate the immobiliser completely? So that you can check that it is actually due to the power supply of the injection system? Before it was in the garage for the last 2 years, everything worked flawlessly Fat Boy FLSTF from 2008 Maybe one has an idea how to tackle the problem. Thank you Andy48
