Why is my coil wire getting hot?
A bad spark plug ignition cable will have a much higher than normal resistance. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation. Wear and tear. The reduction in insulation can cause the coil to overheat.
Can a bad ground wire cause no spark?
Bad grounds can cause no spark issues though. It can cause the ground to ground through the ecu frying it. If you get a single spark when turning on the ignition then nothing when cranking it’s the ecu. It’s a really good idea to go over all your grounds on a regular basis anyway.
What kind of coil is needed for hotspark 4 cylinder ignition kit?
Coil with 3 Ohms or more internal, primary resistance required for 4- and 6-cylinder ignition kits. Coil with a minimum of 1.5 Ohms primary resistance required for use with 8-cylinder ignition kits. Beru Germany Blue Coil is ideal for HotSpark 4- and 6-cylinder ignition kits. Requires a 12-volt, negative ground electrical system.
Why does the ignition coil polarity affect the spark?
The simple fix for this is to reverse the two primary wire connections on the ignition coil. Because the output spark is very much higher voltage (20,000v) than the car battery (12v), it doesn’t care if the battery polarity is helping or hindering by a meager 12 to 14 volts in battery potential.
Is the Bosch black coil compatible with hot spark ignition?
The Bosch Black Coil (made in North America) has 3.4 Ω primary resistance. Ideal for use with 4- and 6-cylinder Hot Spark ignition kits. The following 12-volt Bosch® coils should be compatible with the Hot-Spark electronic ignition module (4-and 6-cylinder): 00 015
What causes a hot spark ignition to fail?
Using a coil with insufficient primary resistance can cause the ignition module to overheat and misfire until it cools down again, or fail prematurely, which will void the Hot-Spark ignition warranty. Check the voltage reading at the coil’s + terminal, engine running, at maximum RPM at the coil’s positive terminal.
