Can a coil be repaired?
While coils can be repaired, refurbished and replaced, this must be compared to the cost of providing a new unit.
Where does the Black Wire on Bosch ignition go?
The black wire connects to negative ( – or 1 on Bosch coil). Connect any other wires to the coil in their original positions. This ignition module is designed for 12V negative ground applications only. Do not connect either of the coil’s terminals ( + or – ) to ground (earth).
Where does the wire run on an ignition coil?
Check the engine repair manual for your make and model car before beginning work. Locate the positive coil wire, which runs from the ignition switch to the positive terminal of the ignition coil. On later model cars, this wire may run back to the car’s computer or the ignition control module.
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.
What’s the Red Wire on a hot spark ignition?
Wiring a 1.4 O ballast resistor between the coil’s + terminal and the red HotSpark ignition module’s red wire decreases excess voltage going to the ignition module, helping to protect the module from over-voltage and voltage/amperage spikes. Customers occasionally return ignition kits to us that have failed.

How do you wire a 12 volt ignition coil?
How to Wire 12 Volt Coils Disconnect the black negative cable on the negative post of the battery. Look at the ignition coil. Connect one end of the spark plug wire to the large center terminal of the ignition coil. Connect the positive terminal of the ignition coil to the ‘On’ terminal of the ignition switch.
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.
Where is the negative coil wire on a car?
Locate the negative coil wire. On most cars made before 1980, this wire connects to the points switch, which is located on the distributor. The distributor connects all of the spark plug wires. Most newer cars do not have a points switch, so that terminal is connected to ground or the negative terminal of the battery.
