The idea is to use an 8 volt coil and punch 12 volts through it when you have a cold start. This gives a better spark at the plugs and makes it start easier. When the resistor gets warm, it cuts the input voltage to the coil back to 8 volts and you have a normal secondary ignition circuit. That's why you find coils marked as "use with resistor". Run one of those without a resistor and it won't last too long.

It just could be that this is your problem as there is a heat related element involved here i.e. an open circuit or high resistant connection will allow the engine to fire, but it will not continue to run when the start circuit is not running (i.e. via the ignition key). As part of routine maintenance once in a while it certainly doesn't hurt to pull the resister apart and clean up the connections - you'll need an 8mm spanner if it's a stock item on your car. regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of David Andrews Sent: Sunday, 3 August 2003 9:57 AM To: [EMAIL PROTECTED] Subject: Re: Wierd and annoying ignition breakdown I've been meaning to ask about this. All the coils I've been using have ``Use with resistor'' printed on them. How do I check this resistor? I have no idea what/where is it.
