| 1. Disconnect high-voltage wires from candles and ignition coils. | 
  | 2. Clear and check integrity of isolation of high-voltage wires. | 
 
| 3. Check internal surfaces of contacts of high-voltage wires on absence of corrosion or a deposit. | 
  |  | 4. By an ohmmeter measure resistance of high-voltage wires. Resistance: 16 kiloohms/m |
