Ignition Switches


A worn solenoid contact or low battery power, which creates starter clicking, because of high resistance, can and will affect the ignition switch or starter relay contacts.

Clicking will cause the current to stop flowing through the pull in coil of the starter solenoid. This high current (around 30-40 amps) is well above the design limit of the tiny ignition switch contacts that are made to carry the hold in current of the solenoid (less than 10 amps). This is the most common on GM, Toyota, Nissan, & Honda. If the driver lets the starter clicking go for a long time, ignition switch replacement may be necessary.

Chrysler has a 20 amp fuse for the starter. Once the fuse blows out it's a sign to change the starter.
