Spark-ignition engines with turbocharger or direct fuel injection require higher spark energies. The high voltage connection between ignition coil and spark plug must be functional and safe. This is where BERU comes in with high-quality ignition cables with suitable contacts or high-voltage ignition coil connectors. 5 OPERATION OF IGNITION
Ignition Using the Ignition as a template, mark the location of the mount-ing holes on the mounting . plate. Remove the ignition and drill a 1/4” hole at each marked location. Mount the ignition using 10-32 x 3/4” or 5mm x 16mm stainless steel bolts (not supplied). Ignition Coil - Not On Plate

Accounting involves recording business transactions and, this in turn, leads to the generation of financial information which can be used as the basis of good financial control and planning. Inadequate record keeping and a lack of effective planning ultimately lead to poor financial results. It is vital that owners and managers of businesses recognise the indications of potential difficulties .
