My Petronix problem. Help Please

[Dejammey]

I installed a Pertronix 1847v on my 76 2002 the other day and can not get the car to run correct.

Once I installed the system into the car it would crank but not stay running. I the removed the Ballast Resistor from the car and ran they yellow ignition cable and the red Pertronix cable straight to the positive side of the coil. That got the car to run but very poorly. I drove the car down the street and it would run but the car would bog down if you gave it to much gas.

I put pictures below to give you a idea of what my setup looks like. If you have any ideas at what the problem might be it would be a big help.

Thanks,

Sounds like your timing is off. Did you reset it after you installed the Pertronix?

[mbaze]

Yes, you're timing is off. Same thing happened to me. Get the car running by cranking up the idle screw so it will stay idling, then loosen the distributor nut and gently turn the distributor until you get a decently smooth idle. Then, at normal running temperature, do a more fine-grained timing with a timing light at the correct idle speed, etc.

Oh, and by all means, put that resistor back on, and make sure the wiring is as illustrated in the Pertronix instructions.

My car wouldn't start after installing the Pertronix on my tii (about 1 year ago). I bypassed the ballast resistor like the instructions said, but it would only start after I reconnected the resistor. Then I noticed the resistor got extremely hot, so I put my old points and condensor back in.

Now running a new Bosch distributor with points (and stock resistor) and all is fine.

Thanks guys ill give it a try!!!!!!

One other thing. I noticed you are running the rev-limiting rotor inside your distributor. Seems these rotors are not highly regarded in the 2002 community (even though my car has one). If your car starts fluttering at RPM's lower than your redline, you may want to change out the rotor to a standard one.

[mbaze]

Is that what that is? My '74 came with one of those rotors, and I always wondered why it was different. What's the point of it?

[dharvey]

Early form of rpm limeting distributor, spring holds contactor untill it gets to what ever rpm will pull it away.

Hense the limet of rpm is controleed by what ever that particular spring tension is......

I never could get the Pertronix to work in my '76 after trying all of the above plus some other things, so I went back to points. The little guy's been running great ever since.

With a blue coil, you do NOT NEED extra ballast. In fact on your '76 you now have DOUBLE ballest installed, because the wire feeding the coil also has a resistor built into it.

If you want to use your Bosch Blue coil:

1) Run a new wire direct from fuse position 12 to the +12V on the coil.

2) Hook up pertronix, be sure to re-route your leads. Having them stretch across the engine bay is just asking for a failure (broken wire).

3) Yes, you will need to reset your timing for sure as others have described.

The "hall effect" points replacement has been around for years, they've been proven to work.

My bad. I didn't notice that was a blue coil. No ballast needed.
