With full headlights on for at least 2-3 minutes, do they dim at all when you try the start?
What is the click?
Is it the click of the starter solenoid engaging, but the starter doesn't crank?
Can you start by bridging that solenoid? [not recommended unless you know how]
Voltage across battery with no load, vs across battery with headlights on for at least
Voltage from battery to starter solenoid
Voltage from battery to frame vs voltage across battery
Where it may well be something in any after market theft device as opposed to weak battery, loose ground, dirty cables--although those are always the place to start.
Transmission type, and in park or not [can be bad switch, but then you should not get any solenoid click at all...]
