Should there be 12 volts on both sides of the coil?
You need to read the voltage across the coil post, not with a lead connected to ground. It is a coil which is nothing more than a very long wire,so you will see 12 volts on both sides if you refrence your meter to ground. Check and make sure the distributor is turning.
How is a single turn coil different from a multi turn coil?
If the coil is made up of single turn or a single loop of conductor, it is called single turn coil. If the coil is made up of more than one turn of a conductor, we refer it as a multi-turn coil. A single turn coil will have one conductor per side of the coil whereas, in multi turns coil, there will be multiple conductors per side of the coil.
What does the passenger side coil pack do?
The passenger side coil pack gets one switching signal that activates spark for ‘Paired’ Cylinders #1 and #6. The other switching signal activates ‘Paired’ Cylinders #3 and #5.
What happens when the coil span is less than the pole pitch?
If the coil span is less than the pole pitch, then the winding is referred as fractional pitched. In this coil, there will be a phase difference between induced emfs in two sides, less than 180 o. Hence resultant terminal voltage of the coil is vector sum of these two emfs and it is less than that of full-pitched coil.
Where are the coils located in an armature winding?
In other words, we place one coil side in each armature slot. We refer this arrangement as single layer winding. In other types of armature winding, arrangement two coil sides occupy every armature slot; one occupies upper half, and another one occupies the lower half of the slot.
Why do I get less voltage at the coil?
Although, even without the resistor, you’ll get still more voltage at the coil since the new wire run is short compared to the wire from the ignition switch – less distance means less voltage drop.
What happens if there is no external signal to the ignition coil?
With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. A switch, or signaling device, triggers an interruption in the circuit.
How many volts does a 3 foot DC coil lose?
Using a voltage drop calculator, 10 amps @ 12 V dc, 20 foot #10 wire = 6.7% voltage drop = 11.2 volts at the coil; versus a 3 foot run loses 1% = 11.9 volts at the coil.
What’s the normal voltage for an ignition coil?
Normal reading on the primary windings is 1.6, but 1.5 is still within the acceptable range, so this by itself doesn’t necessarily indicate a problem.
