I have replaced everything involved in my ignition system but still lose spark after driving for a short period of time if you le tit sit for an hour it will restart again any suggestions?

did you have your ignition coil replaced? the signs are that the ignition coil is overheating thus you are able to restart after an hour, when the coil cools. also check if your ignition coil has a resistor. if it has, have it checked for continuity. did you have your ignition coil replaced? the signs are that the ignition coil is overheating thus you are able to restart after an hour, when the coil cools. also check if your ignition coil has a resistor. if it has, have it checked for continuity.


When is the resistor bypass used in the ignition circuit?

The resistor bypass in the ignition circuit is used when starting the engine. It bypasses the resistor to provide full battery voltage to the ignition coil, ensuring a strong spark for a quick and reliable engine start. Once the engine is running, the bypass is no longer needed and the resistor is re-engaged to limit the voltage to the ignition coil for normal operation.


How do you replace a coil on 2003 Chevrolet Express?

REMOVAL PROCEDURE Remove the engine cover. Disconnect the spark plug wires at the ignition coils. Disconnect the ignition coil harness connector. Remove the ignition coil mounting bolts. Remove the ignition coil. INSTALLATION PROCEDURE Install the ignition coil to the bracket. Install the ignition coil mounting bolts. NOTE: Refer to Fastener Notice in Service Precautions. Tighten Tighten the ignition coil mounting bolts to 8 N.m (71 lb in) . Connect the ignition coil harness connector. Connect the spark plug wires at the ignition coils. Install the engine cover.


What is the difference between a ignition coil and a pick up coil?

Ignition coils are generally external while pick up coils are generally internal to distributor


Where is the porcelin ignition ballist resistor for 1986 dodge half ton?

ballast resistor should be on the firewall under the hood. just follow the wires from the coil and you will find it


Why reduce voltage from a ignition coil by putting a resistor in the spark plug?

Sometimes a resistor is installed in spark plug wire as a supressor to reduce radio static interference


Is the ignition coil resistor necessary?

Yes definitely it is necessary because when u crank the engine at that time ignition coil is in cold position so at that time complete 12 volts bypasses the ballast resistor but when u releases the key from cranking position so the key comes to the ignition position at that position 12 volt of battery goes through the resistor that may be approximately 9 volt because when engine starts the coil temperature increases and there is no need of 12 volts


Where is the ignition coil on a 2000 mercury villager?

If your car has an external coil, it will be bolted to the engine near the distributor. Otherwise, it is inside the distributor housing.


Does a Chrysler 5th ave 88 have ballast resistor?

yes its located on the p/s firewall next to the ignition coil


What is the difference between a magneto and a coil?

An ignition coil requires external electrical power. A magneto requires only mechanical power to create an ignition spark. If an engine HAS no electrical power (lawnmower, tiller, chain saw) then a coil would not function.


Why does your 79 cj only have 10 volts at the coil while running?

The ignition only needs 12 volts for starting. You`re wiring harness has a resistance wire or ballast resistor to drop the voltage to keep the ignition coil from burning up.


Where is THE ignition coil resister located on a 1967 Chevelle?

look for the small braded wire coming out of the fusebox under the hood and that is the resistor wire.
