Re: last question on electronic ignition!

[Schuyler Wrobel <sky62@xxxxxxxxxxxxx>]

I've been doing some checking and it seems that most coils for are  
cars are 12v coils, rather it be a MSD blaster,
Flame-Thrower, Accel Super Stock etc... what's different is some are
internally resisted with different primary resistances rated in Ohms,  
just like the
ballast resistors are... ? it seems the lower Ohms rated coils, say . 
7 Ohms - .85 Ohms
have a higher maximum voltage rating like 45,000v, compared to 1.5  
Ohms with a
maximum of 40,000v. there is also a secondary resistance, rated in  
Ohms, and a
turns ratio etc... but, although, it still isn't 100% clear if you  
need the ballast resistor with the
Mopar ECU? I'm reading stuff like the resistor is "Absolutely  
required for points-triggered
ignitions equipped with coils that do not feature a built-in  
resistor." ok or

"No ballast resistor is required when using Accel 41000, 51000,  
61000, or 71000 series
Electronic Breakerless Distributors or when using Accel 300+ Ignition  
Control Modules,
no matter what coil is used."

and the "Mallory Heavy Duty Porcelain Resistors have a 200 watt  
rating and use threaded terminal connections for better wire  
retention. Available for most standard point type or electronic  
ignitions. This resistor has variable resistance values for improved  
coldweather starting and is a direct replacement for old Mallory Part  
#650-25750-38 and #650-28127."

JEGS ballast resistor is designed to be used on low resistance  
ignitions such as breaker point and some optical trigger breakerless  
systems. Ceramic construction prevents overheating of the system for  
durability while maintaining consistent coil current and spark  
duration. Rated at 1.6 Ohm.

and I'm still looking, but I can not get a clear cut answer on  
bypassing the MP ballast resistor, when using a
Mopar ECU, and one of these internally resisted coils ?? BTY there is  
no indication that the
Accel SuperStock Coil is internally resisted? so, Rich, what do you  
think? how hot is your coil getting after
10 or 20 min. of use? I say if nothings heating up to much then maybe  
your ok. all I know, is my resistor
gets freaking hot and my coil after an hour long trip is just a  
little to warm to touch?

clear as mud eh.
