    what is freon?

  • Matthew Boulden Feb 06, 2012

    Freon is the gas/liquid that comes in super cold and pulls the heat from the house. As it goes through the a-coil the fan blows across it making the air cold. It exits the coil and returns to the outside unit.

It is the coil that is on top of or below your furnace that the freon flows through to cool your house when your ac is on. To locate it you need to follow the two copper lines that are going into the furnace, they are connected to the a-coil.

No spark from coil to distrubuter


Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

I need to wire 3 woofers but 2 are dual voice coil and one is single voice coil


sure, if you wish to wire them all together, wire the first dual voice coil subs first voice coil negative to 2nd voice coil positive, second voice coil negative to single voice coil sub positive, and single voice coil negative to 2nd dual voice coil subs 1st voice coil positve (again with the second dual voice coil sub, run the first voice coil negative to the 2nd voice coil positve) your speaker leads will be attatched to first dual voice coils 1st voice coil positive, and 2nd dual voice coils 2nd voice coil negative)

Spark Plug change


An individual ignition coil (1) is used for each spark plug. The coil fits into machined holes in the cylinder head. A mounting stud/nut secures each coil to the top of the intake manifold. The bottom of the coil is equipped with a rubber boot to seal the spark plug to the coil. Inside each rubber boot is a spring. The spring is used for a mechanical contact between the coil and the top of the spark plug. These rubber boots and springs are a permanent part of the coil and are not serviced separately. An O-ring (2) is used to seal the coil at the opening into the cylinder head.

1. Depending on which coil is being removed, the throttle body air intake tube or intake box may need to be removed to gain access to coil.
2. Disconnect electrical connector from coil by pushing downward on release lock on top of connector and pull connector from coil.
3. Clean area at base of coil with compressed air before removal.



4. Remove coil mounting nut (2) from mounting stud.
5. Carefully pull up coil from cylinder head opening with a slight twisting action.

6. Remove coil from vehicle
