1. Check the Switch

A bad switch is among the most frequently encountered ignition issues. It functions as a bridge between two contacts, controlling when relays activate and deactivate. Because it isn't able to harness the full power of devices like the starter, it's a lighter component that's less likely fail. However it's still possible for the switch to get damaged or damaged or corroded.

This could be a solenoid, battery or the van ignition repair coil.

Disconnect the electrical connector from the ignition switch so that there are no other components that could interfere with your test. Set the voltmeter to the resistance or continuity modes and connect one lead on one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter is "open" or fails to detect any voltage, you must replace the switch.
