PaulBallamy Posted December 8, 2014 Report Share Posted December 8, 2014 I have just noticed that my 1969 Herald 13/60 is fitted with 10000 ohm resistor plug lead caps, I'm not sure if this is right, it seems too high ? Should it have resistor caps at all, and if so what should be the correct rating? She is fitted with non-resistor NGK BP6ES spark plugs, and standard points, condenser & coil. (some misfiring under load when cold has been experienced) Any comments, or suggestions please. Thanks Paul Ballamy Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 8, 2014 Report Share Posted December 8, 2014 you dont want resistive anything on our cars, all quite useless, I guess these were in the form of use for radio suppression, unless youre using medium wave most FM frequencies dont seem to pick up ignition intereferences you need all the spark you can get so youre right to never use plugs with an R in the suffix and suggest respectful disposal of the caps in the bin Pete Link to comment Share on other sites More sharing options...
PaulBallamy Posted December 8, 2014 Author Report Share Posted December 8, 2014 Thanks, Pete I'll treat her to a new set of HT leads - I'm surprised she was running at all with such high resistance caps! Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 9, 2014 Report Share Posted December 9, 2014 Think thats a good move let us know if things improve pete Link to comment Share on other sites More sharing options...
