Another option that I like are the petronix conversions. Two wires and jump the ballast and done. They work great. Really all about what you want to do with the car, just like a curve.
I already did, but with one MJ00005 transistor (the closer I could find, just to test for the fix) which was one I found at a local electronic shop in Venezuela. I just made the pot cut on transistor area and got success getting back to life the Module. Just need to replace it now with the NOS MJ00012 I found on eBay later.Hi rev and chrome box are 1.5 Good luck changing the transistor getting all the potting out and that also does not mean that is the problem. Chrome box is funny it tells you use a .25 ohm ballast. Run that on the street you will be pushing the car home in a day. Thats for racing only it gets the box hot but colos between runs. You can use a .8 on the street but the RPM's drop. Overrated for the price now and not needed kind of like the gold or Blue box. The hi rev never even heard of one failing and rated 7500 RPM which most people will never see over 5K RPM
Prices are completed ECUs..Are those prices fully assemblies ECUs? Or just transistors prices?
If full unit price, I don’t think they are expensive at all. EXCEPT if expecting a 10000% profit of course!
IMHO getting a decent stock replacement box like the later blue ones into the $25-40 price rate and good Orange replacement into $45- 60 price rate could be nice. And chromed unit similar slightly above of that.
Once again except if expecting a 10000% profit… what is mostly sure the main reason why nobody is making them.
On a 1 usually from .8-1.0 HOTYes, Nichrome wire, but it does not quadruple it's resistance when it heats up.....
Using THAT logic, the std 0.5 ohm bal res would be 2 ohms when hot & the stock 1.5 ohm coil would only be working on 5 volts.
Note that the amount of resistance increase through the ballast resistor is based on multiple factors including run time, temperature, input voltage plus the construction makeup of the nichrome wire for the % of aluminum/copper/steel used. For the mopar 0.25 ohm ballast resistor (P2444641) in my RoadRunner, I have not measured the actual resistance of the resistor under operating conditions but did measure the input and output voltages @ the ballast resistor terminals after running the car for about an hour. The input voltage was 13.2V and output voltage was 9.8V, so the actual voltage drop was 3.4V or 26%.Yes, Nichrome wire, but it does not quadruple it's resistance when it heats up.....

P4120889Cool… if that’s true (and I’m not saying is not) why they were offering them to be matched with Mopar performance ignition systems even with 1/4 ohms (to some cases)?
Mopar Performance P4876732
And also… what are the specs of the coils from the Chart? Specifically the P4120889…
A. Ignition Coil, High Performance For all 12-volt applications. Not recommended for engine speeds over 6,500 pm. Use 1-ohm ballast resistor P5206436. 1 P4120889 Coil , Ignition |
Which alloy of Nichrome wire are you referring to....there are several grades....each is different with different characteristics ?......Yes, Nichrome wire, but it does not quadruple it's resistance when it heats up.....

Are we still talking about toasters , model rocket ignitors and dental restorations ??Which alloy of Nichrome wire are you referring to....there are several grades....each is different with different characteristics ?......

What are your thoughts on Scotch locks?
None of the above....someone mentioned nichrome wire....which alloy?? The common type is 80/20 % nichrome (nickel/chrome) but did you have a specific alloy in mind?? As they have different resistive characteristics and respond differently. ....just curious.....Are we still talking about toasters , model rocket ignitors and dental restorations ??
Depends on the wires size and current ratings....
