The blue/black wire is from the ECU. I'm off to meet some friends. Back tomorrow.
The 2 pins in the solenoid side of the connector.
All you did with was bypass the solenoid. Just proves the starter works. You still have to confirm that the solenoid is ok. Try disconnecting its...
Ah! Quite possibly.
OK the solenoid is OK. So let's look at the ECU. Is the bike in neutral? Is the neutral light on? The stand switch appears to do something but to...
The ECU could be faulty but it would be best to establish whether the solenoid is faulty or not first.
A good analogy finm. In reality while no current is being drawn (the tap at the end is turned off) the voltage throughout the circuit is the same...
These can be useful but I prefer a bulb. These digital/LED things don't draw enough current to show up a high resistance in the circuit.
Yes, just a lamp with 2 wires. I'd just suggest a 21W indicator bulb. With regard to the side stand switch. When the ECU isn't earthing the...
... And Termignoni? Terminyoni
A very good point. It doesn't matter if everything else is in order if the ECU doesn't get a signal from the start button. I posted this starter...
Agreed, using a test lamp like this should establish whether the ECU is providing a ground or not. Connect the test lamp to the battery positive...
Don't complicate things by disconnecting the side stand switch. Test one state at a time.
That's correct. The red/blue is ignition switched 12V so should read 12V all the time the ignition is on. The Blue/Black is grounded by the ECU to...
Quote from Brad Black: I had an M900ie 2002 model with the non linear TPS and 59M ecu come in with a TPS output voltage that did not match the...
That's what I always thought. :upyeah:
If it is written into the map then presumably it should be. I wonder what @chrisw has to say.
No I didn't miss your point Chris. I knew exactly what you were referring to and it has always been my understanding that doing a software reset...
Doing a software TPS reset will have no effect on the ST4s ECU. That function isn't programmed into it. The TPS can only be set mechanical. It's a...
It cuts off the ignition and the injection because both systems are fed from the same relay.
