 I'm surprised it's taken me this long to come up with this, but I can be a lazy SOB when I (don't) put my mind to it. There have been many inquiries, here and on the Archives, from people who aren't getting a spark. The first impulse when seeing the 17th inquiry in a particular month is to cry "RTFM!", followed closely by "Use the f'n search!" With that out of my system, I will acknowledge that the manual is a) difficult to read sometimes and b) not readily to hand in all garages; that, and the search systems on both sites suck to greater and lesser degrees.

   * Check that the cells are full and the plates aren't warped. Top up with distilled water if necessary.
   * Check static (off) voltage (>12v). Charge if necessary (off the bike). Top up cells if necessary.

 **__Coils and wiring__**
 The FZRs have 12 Volt coils, so anything less than 12V delivered to them = a weak spark or no spark at all. When the starter is engaged the voltage delivered drops, but should still be above 10V. Corroded connections can and will reduce the voltage, seriously affecting the bike's ability to fire up.

   * Find your coils. Turn the key switch and kill switch ON. Measure the voltage (versus battery ground) to both coil low-tension inputs (Red/White wires) at the coil solder joints. Anything more than a 0.5v drop from battery voltage can cause a weak or no spark.
   * If the voltage drop is greater than 0.5 volts a likely cause is a loose or dirty ignition connector (located close to the radiator filler cap - Red and Brown wires), and / or the coil low-tension connectors. Clean and check the connectors if needed.

+  * Switch off!
   * Find your coils, and unplug the low-tension connectors. Check the resistance across each coil-side connector - Red/White wire to Grey or Orange wire (1.8-2.2 ohms). Note that this is very low, and errors in the instrument can affect the reading. Be sure to zero your multimeter before taking these readings. Reconnect the coil wiring. Replace the coil if out of spec.
   * Disconnect the battery negative cable (black).

   * Check for continuity between the battery negative terminal and the center-top wire (6-pin connector) or the bottom second-from-left wire (13-pin connector, looking at pins, wires away). This is your safety signal. Inspect and correct wiring if no continuity. The main relay assembly (diode block on the FZR400) may require cleaning or replacement.
   * Check Neutral , Clutch, and Side-stand switches for security and function.

 **__What happens if you have spark on some cylinders, but not others?__**
 This is a better situation than 'no spark', since it means that almost everything is working!
