2000 Sprint ST wonít start

So about a month ago my 2000 Triumph Sprint ST wasnít starting. Turns out I needed a new battery and a new solenoid. I replaced both but now when I go to start the bike all I get is a click and the headlights cut off when I press the starter button. Iím getting good voltage to the solenoid and itíll start if I short it with a screwdriver. The horn works and I canít seem to find where thereís a shortage in the wires IF thereís a shortage in the wires. Iím stuck on where to go from here. Any suggestions are greatly appreciated.

Seems that you have a problem w/ your clutch lever switch. Try to clean it first.


Do you actually see 12V on the solenoid command terminals when you press the start switch?

Haven’t checked the clutch lever switch. When I check the voltages I get 12.4 on battery and solenoid terminals. When I press the starter switch voltages go up to 12.9 on the solenoid...no idea why it would increase.

Isn't it because you lights are switched off?
I am speaking of the command pins. Not the switched pins regarding the voltage.

Yeah looks like I’m getting the right voltages and resistance everywhere. Checked the clutch switch and headlight cutout relay and those seem to be working fine. Makes sense why voltage increases with the headlights cutting out.
