I have a 1995 Peterbilt 377. Truck wouldn’t start without jumping solenoid on firewall. Replaced solenoid and done same thing. When I jump solenoid won’t start until I press start button but when I press start button without jumping solenoid I can hear the solenoid click. I’m confused either new solenoid is bad or start button bad but wondering why I can hear the solenoid click it button is bad? And ideas?
Start solenoid
