Making your off-road bike last for years and years can be expensive. However, you can cut costs significantly with the help of this handy Suzuki 125-400 Singles repair manual. It's a great way to not only save money on mechanic costs, but also get to know your Suzuki motorcycle better than ever before. It's incredibly satisfying to be able to handle most maintenance and repair issues that come up rather than having to turn your bike over to a mechanic to get the job done.

Because this repair manual covers a number of models from 1964-1981, it's a must-have for any Suzuki collector. Rather than having a 1974 Suzuki TS125 manual, a Suzuki TC125 manual and a bundle of other books floating around, get this all-in-one guide to the most popular models from this classic era in Suzuki history. This manual by Clymer covers the following 1964-1981 Suzuki 125-400 Singles models:

• Suzuki TC125, through 1976
• Suzuki TM125, 1974-1975
• Suzuki TS125, through 1979
• Suzuki TC185, 1974-1976
• Suzuki TS185, through 1981
• Suzuki RL250, 1974-1975
• Suzuki TM250, 1972-1975
• Suzuki TS250, through 1974, 1980-1981
• Suzuki TM400, through 1975
• Suzuki TS400, 1972-1976

This chapter discusses operating principles and maintenance of the ignition, lighting, and charging systems. FLYWHEEL MAGNETO A flywheel magneto is the source of electric power for the ignition and electrical systems of most machines covered by this manual. Separate coils within the magneto supply current for ignition, daytime and nighttime operation, and battery charging. Alternation current produced by the magneto is used for ignition and lights, except for stoplights and turn signals. A rectifier converts this alternating current to direct current to charge the battery and operate the horn, brake light, and turn signals. Figure 1 is an exploded view of a typical flywheel magneto. MAGNETO OPERATION Figure 2 is a diagram of a typical magneto ignition system. As the flywheel rotates, permanent magnets attached to the flywheel revolve past the windings in the magneto, thus inducing current in the windings. When the contact breaker points are closed, the current developed in the ignition coil is grounded, and no current is delivered to the ignition coil. When the points open, current is delivered to the primary winding of the ignition coil. The voltage across the coil primary winding is stepped up to the very high voltage (10,000-15,000) required to jump the spark plug gap. A capacitor (condenser) is connected across the ignition points to prevent them from arcing as they open. Nighttime lighting imposes an additional load on the magneto. To accommodate the different current requirements, the lighting coil is tapped for both day and night loads. Note that the lighting coil serves mainly to operate the headlight, but also furnishes power to the speedometer and high beam indicator bulbs. If the headlight burns out, the other bulbs will burn out because of the excess voltage available. The magnetos on PEI (Pointless Electronic Ignition) models are similar to those on the conventional magneto-ignition models, except that the ignition coil is replaced with an exciter coil and a pulser coil to meet the requirements of the capacitor-discharge ignition system.
