There are a couple of other things we must check before sending in for repair.
There are two basic types of Motoplat stators. This by the way is not the rule. There are exceptions.
One has red insulators the other has clear insulators. These are found on the ends of the blue and black wires coming from
the Motoplat stator. The only real difference is the absence or presence of a diode in the Motoplat stator. This will be used
to select the proper test procedure (Red or Clear) in the next step.
Making Sure the Motoplat 6 Pole is Faulty
Testing the Red Insulator Type:
1. Disconnect the black and blue wires from the ignition coil making sure that the blue wire to the kill switch is also
2. Using an Ohmmeter check for a reading of 16-24 ohms between the black and the blue wires.
3. From the blue wire to the metal on the Motoplat
Check for a resistance reading of 160-220 ohms
If the readings are not correct the Motoplat is faulty.
Testing the clear insulator type:
1. Disconnect the black wire from the ignition coil. Disconnect the blue wire from the ignition coil and the kill switch.
3. Connect one lead of the ohmmeter to ground. Connect the other lead to the blue wire. Note the reading. Interchange
the test leads and note the second reading. In one connection the reading should be infinity, in the other, 3,000 to 9,000
ohms should be indicated. If a reading of very low resistance (0 to 50 ohms) is obtained in both cases, then the diode is
defective. If a reading of very high (over 15,000 ohms to infinity) resistance is measured, there is an interruption in the
