question about detailing + Ignitor, the sequel

[Olivier 3.0]

first I'm detailing the fan and its housing on my Carrera 3.0; but how can I make-up the belt around the housing? Do I have to sandblast it and then paint it, or vernish it? is it better to just clean as well as I can? I succeed in getting the right sticker to put n it, so it's not a problem to sandblast it ... Your advice?

For those who have followed my Ignitor problems, I sent a fax (no e-mail address on the Pertronix website ) yesterday and Bob from Pertronix send me a kind e-mail very quickly. He says that the correct wiring for 911 is a switched "+" source for the red wire and to connect the black one to the wire which formerly went from the CD box to the points, and let the other wires connected as before; nothing else. I didn't try yet, but I'm a bit confused: the wire formerly connected to the points is not supposed to transport "+" signal? and the Ignitor black wire is supposed to be connected to the coil's "-" in the notice ...does Anybody have a clue, before I do wrong?

Try this for an explanation that may make more sense to you. I have a 76 911s (2.7L) with Bosch distributor and I think your configuration should be similar.

1. The red wire goes to a positive source. There is a fused outlet on the electical panel on the back of the driver side rear fender. You want the side after the fuse. On my car I used the innermost fuse at the front end of the fuse block.

2. Before changing out the point system, the points have a insulation block that hangs out the front lip of the distributor beneath the cap. On the exterior surface of the block is a male spade connection. A black wire with female connector from the harness used to connect to the spade and so the points, and then to ground via the closed points. Connect a male spade to the black wire from the pertronics module.

3. Of course, both the red and black wire should be threaded through the rubber plug that hangs out of the notch in the front lip of the distributor. Install the pertronics module, set the gap. then set the block in the distributor notch so is set in flush with the distributor lip and the cap can be closed down. Attache the spade to the black wire and plug into the black wire that used to go to the points. Tape to insulate. Run the red wire along the harness to the fuse block and connect it to switch power (on with ignition key on, off with ignition key off). Back out the screw holding other wires onto this fuse connection block and insert your red wire and tighten. ( I used a thin crimp-on connector to be neat, but the wired twisted tightly should do.)

I'm just another driver who was frustrated with points, but I have what I think is the same set up. Hope this make sense. Going out to check my car to see if I've got this wrong and will re-post you within an hour if my car doesn't look as I've described above. This is fairly simple and you should have a schematic drawing with the pertronics unit.

Good luck.

My previous message was correct. I thought about your first post, and now I'm beginning to think you are reading the wrong instructions somehow. If I've got this correct you DO have a CD unit. In this case the Pertronix instructions are as follows:

"FOR CAPACITIVE DISCHARGE (CD) SYSTESMS.
Connect the black ignitor wire to the CD trigger wire. This is the same wire that was connected to the points. Connect the red Ignitor wire to a switched 12V source. "

Put another way: the only old connection you use is to the black wire that used to go to the points and then to ground in the distributor. The red ignitor wire goes any convenient +12 supply.

The Pertronics unit is a Hall sensor I believe. Think of it as a mechanical switch (same as points) but with a +12 Volt supply to run the hall sensor electronics. Look up the Hall Effect in a physics book if you want to know more.

Good Luck.

thanks a lot for you answer , Grant ; it takes sense to me, and is likely what Bill Hoge from Pertronix told me... I'm afraid that I didn't get the right instructions, because there wasn't any word about CD box... Could you tell me if your Ignitor set was referenced "1863"?
I will try on saturday and let you know.. Maybe a lot of difficulties known by guys on this BB (cf. previous threads) are from bad instructions or incorrect wiring....


Anybody for the detailing of the mettalic fan housing belt ?

Olivier,

My PerTronix unit is a Model Nr. 1867 according to the instructions.
The box is stamped with: Part Number 1867.

I don't know for certain whether or not there is an electrical difference between your #1863 and my #1867. But I'd guess there are different models only because the mechanical adaptor plate must be customized to fit different distributors. There really shouldn't be a need to have a different electronics module.

My unit came with two sets of instructions: (1) a printed set of instructions aimed at conventional coil/ballast resistor systems, with the warranty and diagrams (2) a typewritten (copy) of instructions specifically including the P/N 1867, and detailed installation instructions -- some of which I've already posted to you.

You might want to contact Pertronics to see if they can post this second detailed set of instructions to you, since it appears you don't have these instructions. You could also sort out the P/N differences at the same time. I can send you my instructions, but that won't confirm whether the electronics module is identical -- and Pertronics can do that for you.

Regards and Good Luck
