Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase. Please see the California state government official website for more information: California Proposition 65
Proposition 65 entitles California consumers to warnings for products that contain chemicals known to California to cause cancer and birth defects or other reproductive harm if those products expose consumers to such chemicals above certain threshold levels.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are:
Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
Fundamental Electrical Troubleshooting (FET)- the SHOPbook revised edition, now with 200 pages. More information on diagnostic methods, better examples of troubleshooting techniques, and still small enough to fit in a top box.
If there's one subject that almost all mechanics need help with - it's electricity. The most difficult part is not being able to "see" what electricity is doing, and this makes it hard to make sense of what needs to be done to repair a faulty electrical system.
This is the book that you've been hoping for. Easy-to-read, but smart and useful. Each page is a one-page-lesson. There are two easy to use indexes, and the book is spiral-bound and plastic-covered so you can use it on a shop table, toolbox, rocker cover or track, and oil and grease won't be a problem.
Some schematics are drawn as a straight line, called "ladder diagrams." If not, you should take the time to read the schematic and learn how the circuit works. Then, redraw the whole circuit as a straight line. Reading the schematic and then redrawing is a very critical rule.
Find the load component first (for instance, light, horn, coil, solenoid or backup alarm), then find its ground, and then find the battery. Trying to read a schematic from positive to negative doesn't work. Always work back toward the battery from the load. This rule is important because it gives you a correct direction. All grounds must eventually end at the battery (not inputs).

One popular course, Fundamental Electrical Troubleshooting (FET), is a fully-integrated, hands-on electrical troubleshooting class designed specifically for technicians and mechanics who work on heavy trucks and heavy equipment.
Sullivan explained that STS methods make it possible for techs to fully understand how electricity and electrical systems work, making them much more effective on the job. The company trains technicians of all skill and experience levels.
