After installing Pertronix ignitor 2, engine runs rough idle

[Anonymous]

After installing Pertronix ignitor 2 engine runs rough on idle and low rpm accelearting.
Coil resistance is nearly zero and voltage is OK.

What's wrong? :

Coil resistance as measured through the primary windings is normally quite low, around 1.5 to 3 ohms depending on the design. It requires a pretty good ohm meter that has been properly zeroed to get an accurate reading. I have never used a Pertronix myself, there are many folks here who can help though.

Jack, see my previous posts on this piece of junk. Return it even if you have a full 12 volts to the coil & have bypassed the resistor. Use the pertronix I with a full 12 volts & a decent coil & your problem will be solved.
Believe me i speak from experience. I also had this problem after replacing a perfectfully working pertronix I with the pertronix II. good luck william

Thanks for your reply,
i called NPD where i ordered the P2 a few months ago, they were not able to just trade it with a P1 but they made a good deal for a P1 so i ordered the P1.
Pertronix was not interested in refund discussion so i have to try to sell it here.
Are there sixes that teh P2 will work on?

You might want to pursue it further with Pertronix, I believe both of the Ignitors come with a 30 month warranty... I know the P1 does, so I'm sure the P2 does too...

Jack, i purchased my pertronix II from virginia mustang. When i had the same problem as you, i called virginia mustang & they took the II as a warranty return & sent me a pertronix I & refunded me the difference.
I did not even have to deal with pertronix at all.
You might try back with npd & request to talk to the manager.
Next time deal with virginia mustang they are great folks to deal with,very customer related. Good luck. just for your information the web site for pertronix. www.pertronix.com :idea: william

I've seen this issue come up a few times now, and I'm wondering if the quality of the regulated alternator output is an influence - I mean waveform. Anyone got thoughts on this? Are people with "issues" using mechanical or solid state regs?

Jack..



if u are willing to sell it i am an interested buyer. Let me know

Thanks again for your reply's, Since i live in the Netherlands i have to try to sell it here.

Today i contacted Pertronix again and talked to their technician, he advised me to remove the resistance wire between ignition switch and coil,

Somebody can tell me if it can be removed without consequence? What is the function of this resistance wire?

Adam, when i installed the pertronix II, i had an electronic voltage regulator on the vehicle. When i bypassed the resistor wire, it did not stall or idle rough as often. Thats very interesting about the voltage regulator. Since i sent my pertronix II back, i can't perform a test on that subject. : william

The function of the resistor wire in a breaker point ignition is to lower the amount of primary current through the points, thereby minimizing burning of the points. With a breakerless system, there are no points to burn, so the primary current can be higher with no ill effects. Your Pertronix may perform better without the resistor.

JaCo...so if I come to the netherlands...you will take me for a ride?

was actually thining about another vacation there sometime...

The resistance wire lovers the voltage to the points and the coil. The stock components were not able to handle a full 12V.

Most aftermarket coils want 12V to them. The Ingitor I does not want a full 12 V as I remember, but does require bypassing the resistor wire. The Ignitor II is designed to run on a full 12V.

Both Ignitor I and II want a full 12v. The Ignitor I is more tollerant of the lower voltage, but they both should have a full 12v. Just bypass the resistor wire or resistor, don't cut up the wiring harness. There is usually a bullet connector a few inches from the ignition switch -- disconnect there.

Thanks again for your response ,
Because i wasn't sure whether removing the resistor wire would damage the (original?) coil, i connected a jumper wire from the ignition switch to the P2.
The engine run a bit smoother but not as perfect as i aspected.
I took the pony for a ride en gues what; after 10 miles the engine stopped,
I checked the distributor and saw that the green tape around the magnet sleeve did come loose and the little magnets came out.
Luckily i took the old breaker points as spare so i installed this set,
Unluckily by setting the gap the signal failed wich was caused by a defective coil.
I think i'm fed up with the P2 for a while.

I have had a P2 in my car for better than a year now. Smooth idle and runs well, no trouble so far. I bypassed the ballast resistor with a full 12 v0lts to the unit.

Russ, you are the luckest man on this planet.I have spoken to many an unhappy owner of this junk & have had a pertronix II on my mustang, & had a full 12 volts to the unit.
I definately had the air gap correct. Sometimes it requires grinding or hand filing the aluminium base to obtain the proper air gap. The base usually interferes with the vacuum advance lever to the breaker plate.
The only way to eliminate this problem is to remove it & install the protonix I. Really ticks me off when its customers have to do the research & development work to obtain a proper fit & get a faulty product.
If a auto manufacturer used this junk, you would have a safety recall because of the stalling condition. The mustangs are at risk for a rear end collision just because of the fuel tank location.
this product could be under legal litigation if someone got injured or killed by this faulty product.
All you attorneys pay attention, this could be a money maker for you & protect your customers safety. all readers pay attention of this dangerious product. william

I also have had the Ignitor II installed for over a year. I have gone on several 6-10 hour each way trips and the car runs great. I get a little under 20 MPG driving at 80 on the highway in my 66 Falcon fordor. I imagine if I drove a little slower I would get real good mileage.

The car runs a little rough at idle, but I just need another 1/4 turn on my idle speed screw and I will be set. I think I'll turn that screw tomorrow.
