What is the order of power to the primary side of coil on 1998 heritage softtail classic


The coil primary is provided 6v directly from the electronic ignition control. (Not sure what you mean by "order of power.")

P0350 Hyundai Description
The ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

There is not really a negative primary coil wire per se BUT ...............

The 2006 carbureted models have a three wire 83B connector with #3 wire being BE/O Front coil wire carrying the primary current supplied from the #2 W/BK wire to and through the front coil primary circuit to the ECM (#2 wire being W/BK and supplying current from the Stop Run Switch to both front and rear coil primary circuits at the same time) and the #1 wire being Y/BE Rear coil wire carrying primary current supplied through the W/BK wire to and through the rear primary wire #1 to the ECM. So, current comes to both coil segments (front and rear) simultaneously, passing both primary windings by two separate wires to ground through/in the ECM until the ECM opens each circuit independently of the other and thereby collapse the current in each primary winding into each secondary winding at the appropriate time to fire the respective spark plug.

The 2006 EFI models have a four wire 83B connector with wire "A" being Y/GN Power supply wire; wire "B" being GY/BE and the ION sense wire to the ECM; wire "C" being Y/BE Rear primary coil segment and Wire "D" being BE/O Front primary coil segment. Again current comes to the coil through the Y/GN "A" wire and passes through the front primary circuit to the ECM via the BE/O wire until the ECM opens the circuit which collapses the front coil primary current into the front coil secondary circuit inducing a high voltage current which then bridges the gap and fires the front spark plug and through the rear coil segment primary circuit to the ECM via the Y/BE wire until the ECM opens the circuit which collapses the rear primary current into the rear secondary circuit inducing a high voltage current which then bridges the gap and fires the rear cylinder spark plug.

I hope this answers your question whichever 2006 Softail model you have.

89 Comanche 4.0 inline 6cyl no power to pump and now no spark as well?


I'll try to help you, John.
For spark: If your spark plugs, spark plug wires, dist. cap, and rotor are good, check the coil. Take off the negative battery cable. Use an ohmmeter and check resistance between the coil primary positive terminal and the frame of the coil-ohmmeter should show infinite resistance, if not, replace coil. Put ohmmeter positive lead on coil primary positive terminal, and ohmmeter negative lead on coil primary negative terminal-resistance should be zero or nearly zero, if not, replace coil. Connect ohmmeter negative lead to the negative primary terminal and ohmmeter positive lead to the high voltage terminal of the coil. Ohmmeter should not show infinite resistance, if it does, replace coil.
If coil is good (or has been swapped), check that coil primary has power to it with key on. If it does, and no spark, the problem could be the ignition module or the pickup coil. The ignition module should be mounted with the ignition coil. The pickup coil is inside the distributor-this pickup coil is what tells the computer (ecu) the crankshaft position, so is critical for spark timing.

For the pump: the fuel pump relay is in the power distribution box under the hood. When the ignition switch's run wire energizes the relay's coil, power is sent to the pump. You could check for a signal on the pump wire at the tank, with the engine cranking Should be a steady signal then. If not, pull the relay out to check that the power feed for the pump is still there. The power to the relay comes from Fuse link G, a 20 amp rated green fuse link. It is hot at all times, so check for a power signal on one of the relay terminals with key off. One terminal should have power. If not, check fuse link G. If it does have power, put relay back in and have someone cycle the key-relay should click-may feel or hear it. If nothing, try a different relay. If relay was good, but no power to pump, pull relay and check terminals that relay plugs into: with key held in crank, two terminals at relay should have power-the power feed from fuse link G, and now the ignition switch signal to the relay coil side. If all checks out, probably a bad pump. If you checked for power at the tank with the engine cranking, and did have power, that is for sure a pump that needs replacing.
Good luck.

P0354 - Ignition Coil D Primary/Secondary Circuit Malfunction.

Description of DTC:
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Symptoms:
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation
- Check Engine Light On
- No spark

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM

Possible Solutions:
- If damage, repair ignition coil circuit
- Replace ignition coil
- Replace PCM or ECM

Miss fires and stots off when I give it gas as codes 1391 ,0351, 0352, 0353,


P1391 - Not a valid obd code.
B1391 - Oil Level Switch Circuit Failure
C1391 - Not a valid obd code.
U1391 - Not a valid obd code.
Its possible you may have misread this code. If it is B1391 that would be the only code with 1391 for your vehicle.

P0351 - Ignition Coil A Primary / Secondary Circuit Malfunction. The ignition signal from the Powertrain Control Module or Electronic Control Module is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM

P0352 - Ignition Coil B Primary / Secondary Circuit Malfunction.
Same repair info as P0351.

P0353 - Ignition Coil C Primary / Secondary Circuit Malfunction.
Same repair info as P0351



Solutions:
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced
PCM or ECM

I'm not gettin power through my ignition or to my distributer therefore I'm not getting spark why is this?


Need to look at ignition module since it provides power to primary terminal of ignition coil. If there is no power to the primary coil, then no power to the second coil. If there is no power on the secondary terminal of ignition coil connecting to the distributor then there is no spark at spark plugs. Good luck

12(q plus q over 3 plus q over 4 minus q over 6)


OK It is a little difficult trying to figure out the fractions you are trying to describe. Are there 3 fractions within the ( ) ? One with a denominator of 3, one with a denominator of 4, and one with a denominator of 6?

If so, the answer is 9q.

You must change the fractions within the ( ) to a common denominator, which would be 12. That would be 8q+3q-2q all over 12. Since it is all being multiplied by 12 outside the brackets, you just cancel the 12 outside and the 12 denominator inside which leaves the 8q+3q-2q which equals 11q-2q which equals 9q.

Thanks for using Fixya.
