Better to post pics this way;
Voltmeter red probe slips into the connector with the white stripe, black probe sits on the top of and makes contact with the fork leg.
with the ignition switch on the voltmeter should read close to 5 volts dc.;
When the sidestand is up it should read 0 volts;
here is a closeup of the black/white connector;
The red probe fits loosely between the brass connector and the plastic cover of the terminal, just be sure to put the terminal on correctly, it should not be easy to slide off the switch terminal.
Theory;
This is a "dry" contact, meaning it carries very little current and is an input to the e.c.u.
As opposed to a "wet" contact that carries the current the switch is rated for like mains light switches.
"Wet contacts tend to clean themselves every time they are operated by melting and cleaning a bit of material to make the contact.
"dry contacts are not self cleaning and are more susceptible to contact failure if not very well designed for the conditions.
So i think the sidestand switch could be the reason your lights came on for a short time because it is an e.c.u. input and the thing to look for is the exact same voltage every time the sidestand is up, ( close to 0 volts is a good contact ) if this value changes a lot the contact is not reliable.
When i tried my sidestand switch over twenty times 19 times it read 0,005 volts and be sure the probes make good contact.
Also wriggle the wiring of the sidestand switch whilst checking the 0 volt reading to check for intermittent contact of the wiring.
