tortron Posted December 23, 2008 Share Posted December 23, 2008 the coil im wanting to use in my flame thrower requires an external resistor think i need it for this use? Quote Link to comment Share on other sites More sharing options...
lowlancer Posted December 23, 2008 Share Posted December 23, 2008 If it's powered off a car battery, then yes. It acts to bump it down from 14.4v, you might burn the coil out otherwise Quote Link to comment Share on other sites More sharing options...
bigfoot Posted December 23, 2008 Share Posted December 23, 2008 you shouldn't do. i never used one when i made a rangi as flamer years ago Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted December 23, 2008 Share Posted December 23, 2008 if its a 12v coil then no, if its less than 12v then yea Quote Link to comment Share on other sites More sharing options...
tortron Posted December 23, 2008 Author Share Posted December 23, 2008 coil is champion performance coil 12 vold cic32r use with external resistor its a starlet coil yuh? Quote Link to comment Share on other sites More sharing options...

lowlancer Posted December 23, 2008 Share Posted December 23, 2008 It will need a Ballast resistor if its a 6v to bring it up to 12v on crank/fire Huh? Resistor to bring voltage up? Is this witchcraft? "The term also refers to an automobile engine component that lowers the supply voltage to the ignition system after the engine has been started. Because cranking the engine causes a very heavy load on the battery, the system voltage can drop quite low during cranking. To allow the engine to start, the ignition system must be designed to operate on this lower voltage. But once cranking is completed, the normal operating voltage is regained; this voltage would overload the ignition system. To avoid this problem, a ballast resistor is inserted in series with the supply voltage feeding the ignition system. Occasionally, this ballast resistor will fail and the classic symptom of this failure is that the engine runs while being cranked (while the resistor is bypassed) but stalls immediately when cranking ceases (and the resistor is re-connected in the circuit)" It depends what type of circuit it's from. If it was from a car that has electronic ignition, you won't need one, if it isn't, you will. Run one anyway, test the voltage after it and see if it is around the 12V mark.

Raizer Posted December 23, 2008 Share Posted December 23, 2008 Ballast resistor drops the voltage to 6V, when cranking the solenoid on the starter motor provides a 12v feed to the coil to boost the spark. Quote Link to comment Share on other sites More sharing options...
lowlancer Posted December 23, 2008 Share Posted December 23, 2008 Yeah, I read Gaz's comment as something quite different Quote Link to comment Share on other sites More sharing options...
Gaz Posted December 23, 2008 Share Posted December 23, 2008 Whoops got all confused with raising voltage from Eke's post. Fixed now/leet Quote Link to comment Share on other sites More sharing options...
sentra Posted December 23, 2008 Share Posted December 23, 2008 Ballast resistor drops the voltage to 6V, when cranking the solenoid on the starter motor provides a 12v feed to the coil to boost the spark. i.e dont bother using it 1 Quote Link to comment Share on other sites More sharing options...
