Checking coil windings resistance (TE-TXC)
Remove saddle and fuel tank (see relevant paragraph) to gain access to the
coil (1).
Disconnect the coil connector from the wiring, remove retaining screws and coil
and measure resistance in the primary and secondary windings with a meter.
Inductive coil:
- Primary winding resistance: 4.5 ±15% at 20°C.
- Secondary winding resistance: 19.5 K ±20% at 20°C (without spark plug
cap cable).
If resistance is outside the specified limits, replace the coil. Also check the
resistance of the terminal cap contacting the spark plug.
- Terminal cap resistance: 4.5-5.5 K ±5% at 20°C.
If resistance is outside the specified limits, replace the cap.
NOTE: The area where the coil is secured must be totally free from oxide
and paint. A faulty ground contact will damage the coil and cause
ignition problems.
