Well if that's what you wanna do.....
The Black/White wire from the dizzy goes to the coil -
The Red wire to the coil +
12V feed into the coil +
NO NO NO that's not what I wanna do. ITS whats been said that can be done.dizzy with electronic ignitions don't need a ballast resister |

tbone that's how we wired it up on sunday.just luck i think me and Brock checked it and that's what we came up with. and is still wired like that
From tbone
you cannot run that dizzy correctly without the 6 wire resistor. Putting a direct 12v feed to the coil will saturate it magnetically, as well as overheat it, both these will cause a poor spark / misfire and eventually the coil will burn out.
The system is designed to be used with that box!

and these are some of the symptoms we had that you have listed above

Erm, would this help?  Spent all day thinking surely I wouldn't be daft enough to throw it away would I? Scoured the barn we store Taz's Dodge in when I got home & sure enough, there it was. So hopefully, crisis averted. -so, can we run a standard 12 volt coil with this? Got one fitted on the Pop at the moment. Or do I need to use the rusty old one that came off the engine when I bought it? No markings on it & no guarantee it's a 9 volt one. We'd love to get the Pop to WheelsDay at Rushmoor Arena, but got no way of getting it there yet. Anyone going -with a trailer? |

that's great Andy.take them to the work shop next time you go.let me know what days/eve you will be there and i will try and come over to have a look and fit them and set up the timing.

dizzy with electronic ignitions don't need a ballast resister [/quote] I fully agree with that statement. What you have however, is an early transitorised occillating pickup. This was one of the first electronic systems developed and unlike later versions, it needs the control that the resistor box gives. Appears we had a slight mis-understanding, I was reading the thread as wanting to dispose of the box, not that it had been lost, I`ll go back to rigging my lobster creels |

I would guess that Andy`s rusty one has C22 stamped on the bottom  I`d go for a coil suitable for electronic ignition, all the V8 non points systems should use the same coil. (these have a primary resistance of 1.0 ohm). And thats the last time i use that R word |

right let me clarify this a bit! The ballast resistor is only fitted to aid starting. if you look at the wiring diagram for a pre 1985 rover v8 dizzy you,ll see its wired to the aux tag on the starter solenoid, Thats to give a constant 12v,s whilst starting, and not cause a voltage drop at the coil. if the power feed is wired direct to a permanent fused power supply to the battery and not a spliced supply as in most cars then the coil and distributor will perform perfectly. I did my apprenticeship at dutton forshaw,s 3yrs on rovers and jaguars  |

The ballast resitor is fitted to reduce voltage to the coil. Electrical componants are made to operate at specific values, you cannot 25% more voltage through without adverse affects.  |

Did I say "one final time......", ho hum! but of course your right Mr.T, run above the rated voltage, and you won't run for long!! Morrag
