The Right Leads Make a Big Difference<br />

The ignition system is the key to full engine power.<br />

When petrol powered vehicles are converted to <strong>LPG</strong> the<br />

ignition system performance must be more efficient. To<br />

ensure this, <strong>LPG</strong> specialists need to look for potential<br />

trouble spots. Ignition leads are sometimes over looked<br />

<strong>and</strong> can make a significant difference to performance.<br />

Always check the following during a <strong>LPG</strong> service:<br />

1. To ensure proper functioning of the ignition system,<br />

ignition leads must be in good condition (not worn out or<br />

damaged) <strong>and</strong> all connections must be tight.<br />

2. The ignition system can be tested with an engine tester<br />

or oscilloscope. The measured ignition voltage should<br />

match the target voltage given by the vehicle<br />

manufacturer. If anything is out of the ordinary then<br />

replace the corresponding ignition cable or component.<br />

Please note: Especially with older resistance ignition<br />

wires, the cable core can break. In such scenarios the<br />

entire ignition cable set should be replaced. Bosch offers<br />

ignition cables for all applications.<br />

A poor performing ignition system can result in:<br />

Rough running<br />

Misfiring<br />

Significant drop in performance<br />

Increased fuel consumption<br />

Danger of damage to other components<br />

Refer to the Bosch Ignition Leads catalogue for further<br />

details.<br />
