NGK 90 DEGREE 5000 OHM, 5K OHM RESISTOR PLUG CAP. AN ABSOLUTE NECESSITY IF YOU ARE RUNNING A SPARX SINGLE PHASE OR THREE PHASE REGULATOR / RECTIFIER UNIT.
***** FROM SPARX ***** Single & Three phase boxes***** “Due to the sensitive nature of both the single and three phase boxes it is VERY important to fit spark plug caps of the 5000ohm resisted type. Failure to do so will cause overloading.”
***** OR AS QUOTED BY BOYER U.K. ***** “MKIII and MKIV do not require suppressed plug caps for operation although we recommend using supressed 5000 ohm plug caps. Micro Digital and Micro Power units must be fitted with supressed plug caps. Plug caps fitted with suppression resistors are usually fitted to prevent radio interference. Radio interference (noise) can cause more complex electronic circuits like radios and computers to malfunction.
Our Micro Digital and Micro Power ignition systems contain a small computer operating at high speed that can be adversely affected by radio frequency interference. Symptoms can range from refusal to start to intermittent engine stalling symptoms. Use of non-suppressed plug caps has been known to cause permanent damage to the ignition unit.”
