Car was not running properly

Hi Nigel,

that would destroy your Pertronix. This power resistor must be serial not parallel in line from Pertronx to coil. It will reduce the voltage on your coil.

Good that Bosch confrmed what I had hinted you to.

Hi Volker.Can you tell me exactly what resister I need IE a model and number because I have no idea about this part.to match with the correct BMW coil.? Thanks Nigel.

Volker just read the Petronix info and it says the coil must have a minimum of 3.0ohms for a six cylinder..Or buy there 40.000 volt version with internal resistance.I will need to see what the BMW one is rated at.

1 224 509 063 is a power resistor with 0,9 Ohm.

Volker thank you Nigel.

Hi Volker.Im pleased to say after many weeks of trying to get the car running properly I've found the problem.It was a faulty throttle switch.also I was give the incorrect information as to how to set it.I have replaced the switch and have fitted a new coil.My Petronix is the so called Igniter one which is a black module and with this there should be a 3 ohmn coil so I bought there version.and I'm pleased to say the old car is back to her normal self ! Going like a rocket.
