Hello all,
Went to start my Monster, turned the key, and nothing happened. No lights, no fuel pump, nothing.
Checked the battery. 13.0 volts. Took it to a battery place and had them load test it and it passed.
Checked the two relays next to the fuse box. Swapped them with ones from another moto. They all work fine in the other moto. None work in the first relay slot. I took all the relays and tested them by putting voltage to them and checking the switch opened and they all passed.
I checked the voltage at the relay plug:
87(+) to 30(-) = 13.0v
85(+) to 86(-) = 2.4v when the ignition is "ON"
85(+) to 30(-) = 1.9v when the ignition is "ON" **Isn't this supposed to be 12v or battery voltage?**
Continuity from 86 to ground is solid.
When I add a jumper between 87-30, everything powers up.
I pulled the jumper, put the relay back in and took the ignition switch from another moto and plugged it in. Nothing.
I have tried following the wires around using the diagram, but I can't make heads or tails of it. Half the wire colors don't match and I really don't want to have to slice open the main harness in order to follow lines.
I did a bunch of searching, but it seems for everyone else who has had problems like this, it was the actual relay. Mine seems deeper, unfortunately. This is my last stop before I take it to the dealership.
Recap:
Turn key, nothing happens.
Battery is good.
Relay is good.
When I replace the relay with jumper everything powers up.
To me the voltage to the relay feels wrong, but I don't know what to check.
Anyone have any ideas?
If replacing the relay with a jumper works, I would think the relay is bad regardless of any other test.
Dirty Duc,
I tested the relays both by putting voltage to them and by putting them in other motos. I have tried 6 different ones and there is still no power up when I turn the key.
How can they work all the other times and not when it is in that exact slot? I am not being snarky, I am completely serious. I don't understand how they could do that.
Forgive me, I'm in an airport and don't have a relay or a Ducati to look at.
There is also a main fuse (40a?) not in the fuse box... And i think the main power for the relay goes through a fuse in the regular fuse box.
Fuses without jumper in place
40amp - 0.8v
30amp (Master) - 2.1v when ignition "ON" / 0v when ignition "OFF"
15amp (Hi+Lo Beam) - 0v
7.5amp (Tail Lights) - 0v
7.5amp (Stop+Horn) - 0v
7.5amp (Injection) - 0v
20amp (Fuel Pump) - 0v
5 amp (ECU) - 10.3v all the time
*edit*
all fuses have continuity on a multi-meter
Should I get the voltages with a jumper in place?
You are correct that the main relay should have battery voltage at 85. 85 is the trigger that closes the relay. Got a wiring diagram? ypu need to start checking back to the ignition switch and kill switch.
