How do you test an ignition wire switch?
Turn the ignition switch until you get to the OFF position. Using the positive lead of the multimeter, put the probe at the back of the power feed wire of the module and the negative lead into the ground base of your distributor. Turn the ignition key to the RUN position and measure the voltage using the multimeter.
What causes an ignition switch to overheat?
This is an accurate sign that the ignition switch problem could be rooted in the electrical system. The ignition switch is connected to a series of high-resistance wires and any of the terminals connecting these wires can overheat. This causes an arcing of the terminals which can melt the insulating base.
What are the symptoms of a bad ignition switch?
Overheating Switch. Another symptom of a bad ignition switch is if it is overly hot when touched. This is an accurate sign that the ignition switch problem could be rooted in the electrical system. The ignition switch is connected to a series of high-resistance wires and any of the terminals connecting these wires can overheat.

This causes an arcing of the terminals which can melt the insulating base. When this occurs, the vehicle will jerk quite violently and will not start despite repeated efforts.
What to do if your ignition switch is bad?
If you get any result showing less than 90% of the battery voltage, you may have a fault in the ignition switch. If you don’t have access to a multimeter, don’t worry. You can still test your ignition switch using a 12 V test light. Turn the key to the OFF position then disconnect the module’s cable connector.
What happens when you wire the ignition kit backwards?
Polarity reversed when wiring the ignition kit (i.e., wiring the ignition kit to the + and – terminals of the coil, backwards). This will fry the ignition module’s electronics immediately. The red HotSpark wire should go to the coil’s + terminal and the black HotSpark wire should go to the coil’s – terminal.
How is the ignition switch connected to the car?
The ignition switch itself is connected to the ignition cylinder by a shaft or lever. Inside the ignition switch, several contacts connect vital electrical systems needed to start and run the car.
What happens if you don’t have the ignition key?
