This webinar is part of "AAPEX Repair Shop HQ Webinar Series: An 8-Part Webinar Series." Sponsored by AAPEX.
The typical repair shop is busier than ever – but what happens when the going gets rough? Many of today’s shop owners have never experienced a significant economic downturn. Has your shop prepared to weather any storms that are on the horizon, or have you just been keeping up with current demands? During this webinar you’ll hear real shops share a “just in case” safety briefing.
The new issue of ShopOwner magazine is now available to read online or download at no charge to you!
Tesla quietly changed the pricing to $0.00 for service manuals, TSBs and other critical service information.
Don’t be fooled into thinking that these pumps will go away with the surge in hybrid and electric vehicle production.
Underhood Service targets repair shops that derive 50 percent or more of their revenue from the service and repair of under-the-hood systems. The expanding amount of knowledge and capital needed to keep up with technological advances has led these shop owners to concentrate on underhood systems, while also offering preventive maintenance services on most major vehicle systems. By subscribing, you’ll receive the ShopOwner digital edition magazine (12 times/year) featuring articles from Underhood Service and the Underhood Service eNewsletter (twice weekly). Access to digital editions, contests, news, and more are ready for you today!

Understanding modern ignition systems will help complete preventative engine maintenance during tune-ups.
Vehicle technology is continually advancing to meet consumer demand for better fuel economy, as well as government requirements for fewer emissions. The result is downsized engines with less displacement for fuel combustion, forcing original equipment manufacturers to design advanced spark plugs using precious metals to improve engine performance and reliability.AdvertisementThese modern ignition systems require dual precious metal spark plugs capable of supplying the highest voltage outputs to date. Original equipment precious metal spark plugs also feature specialized firing and ground electrode designs like dual fine (DFE) and projected square platinum (PSPE). In combination with modern ignition systems, these spark plugs can withstand up to 40,000 kV. Understanding modern ignition systems, and why they increasingly require advanced spark plugs, will help complete preventative engine maintenance during tune-ups. Waste spark systems became popular because of the efficiency and reliability with two spark plugs per ignition coil. While standard ignition systems fire once per combustion stroke, waste spark systems fire twice, once on the combustion stroke and once on the exhaust stroke.AdvertisementStandard ignition systems typically fire with only a negative polarity, sending electricity from the center electrode to the ground electrode. Every time the ignition fires, a small amount of gap erosion occurs on the electrode with negative polarity. In a waste spark ignition system, the coil sends voltage down a spark plug to the ground electrode. On the shared circuit, the paired cylinder is being fired on a waste spark. The waste spark is accomplished by recapturing the remaining voltage through the ground electrode and firing to the center electrode, completing a circuit (Figure 1). Figure 1: Circuit in a waste spark system. The cylinder where the spark travels from the center to the ground electrode will wear on the spark plug’s ground electrode. The cylinder where the spark travels through the ground to the center will wear on a spark plug’s center electrode (Figure 2). Not using dual-precious metal spark plugs can result in uneven wear on the spark plugs and possible misfires. Figure 2: Spark Plugs in a Waste Spark Ignition System Installing spark plug with the correct material types recommended by the OEM ensures long-term satisfaction with customers and prevents unnecessary comebacks with otherwise preventable ignition related repairs.
