If you want to check starter put 12V to the spade on solenoid, it will spin!! Make sure it's in neutral. If it spins it's elsewhere (startus interuptus).
It's definitely more of a clunk. I'm thinking the kill switch might be resetting something to do with the "momentary push" starting feature? I'll look at the battery cables....
Does the LCD screen on the dash blank out for a few seconds after the clunk and then go through its sweep again? That's usually just dirty terminals.Pete
It's only happened twice so far but I really don't want to find out how hard it is to bump start the beast!
You may be correct, if you are resetting something it might be the ECU, are you getting any error codes?Have you ensured the battery is topped up?, I'm wondering if it's tripping on Low VoltageHow many relays do you have under the seat, the Carl Allison drawing shows 5 but perhaps yours is only 4 like mine. http://www.thisoldtractor.com/guzzi007/schematics/2008_Griso_8V.gifFang told me the additional relay called the Startup Maintenance relay was added to latch the start signal ON overriding the low Voltage interlock from the ECU, perhaps yours is resetting on low Voltage at the instant you press start. (see following scenario)Dirty switch scenarioI'm still not convinced it's not an ignition switch problemContacts have become a little dirty over the years building up a fraction of an ohmHuge inrush current to the solenoid pulls the Voltage downstream of the switch down .ECU which is powered downstream of the switch sees the Low Voltage and trips.The kill switch supply is also fed from downstream of the ignition switch, low Voltage might also fool the ECU that the kill switch has just been opened, though why it resets by cycling the switch is still beyond me. I was wrong the Main injection relay supplies the Voltage to the ECU and kill switch.I wish I had a logic diagram of the ECUThere is an upgrade you can do removing the start relay supply from downstream to upstream of the ignition switch. if it were my bike I wouldn't add a relay. I think we have members here who have done the snip and tuck on the Griiso 8Valve yellow wire.I think the wiring on late model Guzzis is the pits quite frankly!!!!!!!!!!!
The battery was just on a battery tender the day before.
