The Suzuki Bandit 1200 motorcycle first debuted on the production lines in 1996 and continued to be manufactured until 2006, although the United States market never saw this last year of production. This bike has a DOHC inline four with 16 valves and implements an advanced cooling system. The spark plugs and wires need to be checked regularly as part of the regular maintenance procedures to keep the bike running smoothly and efficiently.
Pull the lead wire coupler off of the spark plug coil cap (also known as a ignition coil). Thoroughly clean the end of the wire and the metal clips with WD-40 and a washcloth.
Attach a peak voltage adaptor to the multimeter. Turn your mulitmeter on.
Insert the needle pointed probe end into the lead wire coupler. Connect the positive end of the green wire to ignition coil 1, white to 2, black to 3 and yellow to 4. The negative end of each is to be grounded on something metal.
Shift your Suzuki into neutral, turn the ignition to "On" and grab the lever clutch. Hit the "Start" button and crank the engine for a few seconds. Measure the peak performance voltage from your ignition coils.
Repeat the previous step to take a few measurements. Your highest measurement should read 80 volts or more.
Put the couplers back on to the spark plug coil caps.
Do not touch the spark plugs or couplers during testing to prevent injury.
