Stock H-D coils are not "directional". You may put the white wires on either terminal post.

The original wires, one blue and one white, were with the points ignition. The white wire should be the "Hot" wire. Now, look at your wiring diagram. The two white wires should go together to one side of the coil and the blue to the other. There is no positive or negative side of the coil, just two small primary winding terminals. Make sure the white wire from the ignition system is the "hot" or power wire for 12 volts. If you connect the ignition unit up backwards, it will damage it. To make sure the white wire on the bike is the hot wire, simply turn the ignition switch on and check this wire with a test light or volt meter. It should show battery voltage on it. That should be your setup, two white wires on one end of the coil and a blue wire on the other.

Good Luck

I have a 1979 xlh sporty took bike apart to paint on re assembly i hooked up coil wires wrong had no spark fixed wires but could i have killed my coil still no spark.


Ok to test the coil, remove all wires from the small terminals on the ends. Use a digital volt ohm meter and put the function switch in OHMS, R X 1. Touch one meter lead to each of the small terminals. Your meter should read between 2-3 ohms as the '79 model had electronic ignition.

To further test the coil, reconnect the two white wires to one of the small terminals. On the other side, make a jumper wire. Connect the jumper wire to the other small terminal. Put the plug wires into the towers and put a set of spark plugs in the wires lying on the heads with a good ground. Now, turn the switch one. The terminals with the white wires on it should be "Hot". MOMENTARILY, ground the jumper to the engine and take it back loose. When you take the wire loose, you should see a spark at the plugs. If you do, the coil is good and your problem lies elsewhere.

Good Luck

Need coil wiring diagram


Contact points cover open.

Left side points are for cylinders 1 and 4.
Right side points are for cylinders 2 and 3

Left side points have a White wire coming from it.
Right side points have a Black wire coming from it.

One coil runs two cylinders.

One coil runs cylinders 1 and 4.
One coil runs cylinders 2 and 3.

No matter what style of ignition coil you use, the Black wire will connect to the Points. Whatever other color of wire they use, connects to the ignition switch.

BUT, check the specifications for the coils you're going to install. Connect the Negative side to the points. The Positive side to the ignition switch.

The Orange wire with a White stripe, coming out of the harness of the Suzuki Gs550 is from the ignition switch. It goes to a splice connector, and from there goes to two wires. The wires split off into one wire for each coil.

There is a White wire on the coil, that is used for Cylinders 1 and 4.
There is a Black wire on the coil, that is used for Cylinders 2 and 3.

Where does the wires go on the ignition coil Positive Negative?? 1972 Sporster XLH Harley


It makes no difference really but with the spark plug wire towers facing the engine, most of the time the hot wire is on the right side and the wire from the points goes to the left side of the coil.

My wife has a 2003 1200 sposter. It is running


I would check both spark plugs then check the timing and if not fixed check the coil to see if it is bad.

If you mean no output power, coil is bad. If you mean no input power 12v, there is a fault in the wiring. If you mean no signal from stator, wiring problem as well

Gsxr 750 no spark how do i test cdi


I've this data from my 1986 engine!

Under the left hand side cover there are 2 2-wire connections. One with a green and a black wire, one with a blue and a yellow wire.
Use an ohmmeter at R x 100 between both wires of a connector to check the pick-up coils: resistance must be between 130 and 180 Ohms.

The values of the ignition coil resistances are:
primary coil : 3-5ohms ( set ohmmeter at R x 1 )
Secundary coil : 25.000 - 45.000 ohms ( set ohmmeter at R x 1.000 )
For a correct measurement ALL leads must be disconnected ( also the spark plug leads )

The CDI cannot be tested with a simple measurement. Suzuki dealers have a special tool to test CDI boxes.
But checking the pick-up coils and ignition coils good will indicate an defective CDI.

The wires on the CDI:
Blue: PU coil 1 ( cyl 1-4 )
Yellow: PU coil 1
Green: PU coil 2 ( cyl 2-3 )
Blue : PU coil 2
Orange/white : +12v ign coil 1-4
White : switched coil negative side ign coil 1-4
Orange/white : +12v ign coil 2-3
Blue/yellow: switched coil negative side ign coil 1-4 ( and signal to tachometer )
Blue/white : ground

Thus, you must have +12V on both Orange/white leads.
