Getting back to the LED, despite what I said in reply 14 and upon further playing with the system, I cannot get the LED to come on with the key. The unit had 2 faults held in the ABS ECU, one was low battery voltage and the other was ECU trouble - operation abnormal (from a wrecked donor bike). I cleared those faults as per the manual, checked that they were clear, as per the manual, turned off the key, unplugged the front sensor and turned the key on for a bit then off. I put the system back into fault code mode and it had the code 43 - front sensor shorted or open. The really odd thing is that the LED works the opposite way it's supposed to in 'fault code' mode ie, it's on when it should be off and vice versa. I confirmed this by comparing it with my series 1 1400GTR (the type of bike the unit is from) in fault code mode for the same fault - front sensor unplugged, cleared and rechecked both a couple of times. So I have come to the conclusion that the bike's ECU, which is connected to the ABS ECU via the dash/meter, controls the LED and makes it works as it should and that having the bike's ECU out of the circuit on the 1000GTR I'm fitting it to causes the LED to work in reverse - if you follow what I'm on about. Page 12-44 (shown on page 2 of this thread) shows when it should be on and off under which conditions. It's actually off when it should be on and on when it should be off, so instead of counting blinks, I count blanks and get the correct fault code. Follow? I tried wiring in a change-over relay to reverse the operation but the current draw thru the ABS ECU is too low to activate a relay.
Any help on how to get it 'into reverse?'
