Misfiring at 3000 to 4000 RPM - Caused by Voltage Regulator



Q) What spark plugs do you recommend?  A)  We suggest that you check your motorcycle's manual for the recommended spark plugs.

Q) Should I use resistor or non-resistor plugs and caps? A)  Your answer in this blog post

Q) Are iridium spark plugs OK to use? A) There is no harm in using iridium spark plugs like NGK BPR7EIX but be aware that they have a built in resistor for spark noise supression. With these plugs we recommend non-resistor plug caps like NGK LZFH.

Q) Does the Dual Lead Igntion Coil 6 or 12-Volt (IGC-2012, IGC-2006) have a polarity for wiring?  A) They do not have a negative or positive primary terminal so you can wire them either way.

Q) The ignition warning light won't go out on my Norton Commando?  A) The warning light assimilator is not compatible with regulator rectifier units that are currently available.  They were designed to work with the zener diode rectifier set-up from Lucas.
