Will not crank when it rains. Great when it’s dry. What is wrong?
Most likely the starter solenoid getting wet. You may also have one or more rain channels on the body plugged up with debris, or leaks around the cowl, causing water to run down firewall or inner fender and soaking the starter. Try cleaning the solenoid.
