As I understand it it's basically down to whether it's a 6v coil or a 12v coil. For a 6v coil, the resistor is necessary to use up the spare juice, since the power supply is 12v. I assume when you see "ballast coil" it means "this is a 6v coil to be used in a 12v machine with a ballast resistor". I don't think a "ballast" resistor is different to a regular resistor, it's just that it's there for "ballast" or "counterbalancing". Somebody chime in if I'm off down the wrong path altogether here. /// [EMAIL PROTECTED] mailing list /// Send admin requests to [EMAIL PROTECTED] /// or try http://www.team.net/cgi-bin/majorcool /// Archives at http://www.team.net/archive /// Send list postings to [EMAIL PROTECTED] /// Edit your replies!
