To prevent confusion when connecting wires, numbers are marked on later Renault 19 versions, so that the possibility of incorrectly connecting high voltage wires to the ignition coil or wire plug is almost impossible.
- Voltage measurement between terminal «+» and weight; it must be at least 9.5 V.
- Resistance measurement: with the ignition off, remove all wires from the ignition coil.
- Using an ohmmeter with a measuring range of 0-1 ohm and 1-10 k ohm, measure the resistance between the terminals of the ignition coil «–» and «+» (primary winding). The resistance value should be 0.6-0.2 ohms.
- The measurement result on the secondary winding should be 2-12 k.
- Using these measurements, it is not possible to determine the short circuit of the winding in the ignition coil.
- If the secondary voltage of the ignition system is not enough, although the ignition module and the control device are OK, then the ignition coil must be replaced.
Removing the ignition coil
The ignition coil, although combined with the ignition module into a single unit, can, however, be replaced separately in case of a malfunction.
1. Disconnect the ground cable from the battery.
2. Remove the connectors from the ignition coil.
3. Disconnect the high voltage center wire of the ignition coil. To do this, unhook both safety hooks.
4. Remove both TORX screws and remove the ignition coil from the ignition module.
