Check the Following:
Here are the checks to make:
- Yellow wire connected from post on starter switch to terminal box post (post on passenger side of terminal box).
- Ammeter (-) side connects to passenger side post on terminal box.
- Ammeter (+) side connects to driver side post on terminal box.
- Black wire connects from driver side post on terminal box to coil (-) terminal.
- Red wire connects from coil (+) terminal to ignition switch.
- Yellow/Black wire also connects from driver side terminal box post to the cut out terminal. That completes the ignition wiring except for the ignition cable and distributor plate.
- Here is a voltage check of the circuit:
- Connect the (+) side of your volt meter to a good ground point on the engine or frame.
- Touch the (-) probe to the passenger side terminal box wing nut. Read 6 volts.
- Touch the probe to the driver side terminal box wing nut. Read 6 volts.
- Touch the probe to the (-) terminal on coil. Read 6 volts.
- Touch the probe to the (+) terminal on coil. Read 6 volts.
- Place a piece of paper between the point contacts.
- NOW TURN IGNITION KEY ON.
- Touch the probe to the end of the points arm, read 6 volts.
- Remove paper between points. Open and close points and look for spark each time points open, (no spark means bad condenser, replace condenser).
- If points are sparking then disconnect the coil center (high tension wire) from the distributor cap (leave connected at distributor end). Place the free end of the coil wire about 1/8" from one of the engine head nuts. Crank the engine over with the ignition key on. There should be a bright blue arc from the coil wire to the nut (ground point). No arc means bad coil.
