Re: Mallory Ignition Parts
Does anyone know what the 28675A coil is used for?

Re: Mallory Ignition Parts
67BobcatGTO I pm you and have a question. Do you have a N.O.S. coil,the year I need is 1969. If so or not do you have the part number. Thank you. Paul

Re: Mallory Ignition Parts
Paul, my coil is around the early 70's. I just found out. I'm not sure if the blue Mallory lettering and white Mallory lettering tells the tale of the year?

Re: Mallory Ignition Parts
Paul - if Mike does not have your coil there are opportunities to buy them at HAMB or ebay in NOS condition. However,there are a lot of vintage "Mallory Coils" out there for multiple applications ranging from standard to rather exotic-for-its-day (built in Capacitive Discharge). There are also external, stand-alone Mallory CD ignitions that work with standard Mallory coils. Lots of choices. Mike can help you get the right one for your application. The HAMB boys are pretty up on these coils too.
In case you missed it, this is the set up that I restored for my Nova (the coil is NOS and needed very little work): http://img.photobucket.com/albums/v6...DSC_0043-1.jpg |
Re: Mallory Ignition Parts
Sam, what is the difference between your distributor and mine?

If your decal/top plate is blue has nothing to do with the year the coil was made. The red is for 12v negative ground cars-99% of muscle cars and American cars in general. I can't remember exactly but I believe blue is for 12 volt positive ground cars(volkswagons/furren cars??) or something to that affect ..hence it won't work with your car......I can't remember what the blue one was for off hand but but will try to look it up this evening. Hate to give you this bad news. What is the number of the coil? I will look it up in my mallory books and let you know the application. |
Re: Mallory Ignition Parts
Jed - not sure I know if there is a difference. I read Mike's comment on yours. I would be interested to know the range of dates that yours (my) coil were made.

You coil was 66-67 ish to at least the mid 80's. They never changed for th emost part..kinda like the Accel Super coil. The Super Coil made today shape wise is pretty much identical to the ones made in the early 70's other than the decal. |
Re: Mallory Ignition Parts
Thanks all and I will look at the HAMB site,I should try that. Paul

Some are red and blue and others are red and white. I thought that most of the top decals were red for the points negative ground coils? |

The 28675A number is for the Rev-Pol transformer.

Re: Mallory Ignition Parts
Hey Mike,
Can you explain how the rev/pol coil works in conjunction with the rev/pol distributor and rev/pol switch for inside the car? Thanks |
Re: Mallory Ignition Parts
I was pm'd a question about the correct '69 coil.
The correct coil that was available in 1969 is the very one pictured in mockingbirds photo. It has the red/blue large side decal and the early logo on the ID tag. |

Re: Mallory Ignition Parts
Ok, Mike I see that mine is not the correct one.

Re: Mallory Ignition Parts
You don't have a Rev Pol switch do you Paul?

Re: Mallory Ignition Parts
I have pm you. And I do not have one but we can make one. Paul

Hmmm [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] , I was under the impression that the rev/pol switch was for a rev/pol coil AND a rev/pol (dual condenser) dizzy set up. It looks like it works with a single condenser (dual point) dizzy (per the schematic above). So, by reversing the polarity with this switch, does this create more timing advance for racing? Is the advantage with using the <span style="text-decoration: underline">rev/pol coil and switch with the rev/pol (dual condenser/dual point dizzy)</span> that it provides simultaneous spark at each of the 2 points (each with their own condenser) and therefore a hotter spark with the option to advance the spark (with the switch) for racing????? [img]<<GRAEMLIN_URL>>/dunno.gif[/img] I think my head hurts! [img]<<GRAEMLIN_URL>>/crazy.gif[/img] |
Re: Mallory Ignition Parts
From reading the Rev Pol instructions Sam, it seems to me that the 28700 switch bypasses the resistor for racing to eliminate any kind of resistance to the coil to give it a full twelve volts and then knock it down for street? But as I can see from the schematic, there is no second condenser. Even the Mopar Rev Pol that is on eBay now, it has only one condenser. I'm sure that someone else can help on this.

Re: Mallory Ignition Parts
That is one big CONDENSER,next to a stock GM one. I think it can handle it. *Paul

Re: Mallory Ignition Parts
So you got what you wanted,with blue light,is that it because that is looking sooooo cool Jed. What a difference a DAY makes. OH that is only a picture,good luck. *Paul

Re: Mallory Ignition Parts
Yes, just a picture I had saved Paul. But that's what it looks like. The diagrahm that's in that photo is the same one that I have with my Rev Pol coil.

Re: Mallory Ignition Parts
Ok well I finally had some time to dig through my literature and found sales lit on the "NEW" Rev-Pol models.
It states this: The Rev-Pol ignition system changes the direct current to alternating current, which produces a complete reversal of the polarity of the core of the transformer, which in turn produces a long magnetic wave inducing a spark of long duration and of high value every time the contact point open and close. The contact life is twice as long, the rubbing block life is twice as long as in the conventional system. The system will operate any motor to speeds far above the conventional system on less current. It also states the Rev-Pol distributor uses a 4-lobe cam with two circuit breakers for the 8 Cylinder and a 3-lobe cam for the 6 cylinder distributor, giving unlimited RPM with no breaker bounce. -Mike |
Re: Mallory Ignition Parts
Another doc talks about the "new" 10,000 RPM high performance ignitition system. It reads: the NEW street-strip performance switch lets you control current from the dash.
Complete Rev-Pol igntition system produces more voltage faster than any existing conventional battery ignition. Extra hot long duration spark gives top performance at every speed with higher RPM's. The Rev-Pol distributor is hi-performance advance curved for maximum ignition output throughout the RPM range. Special dual points eliminate float and bounce. The Rev-Pol Transformer changes direct current to alternating current and reverses polarity of transformer core to produce a long duration and high value "magneto action" spark. The NEW Street/Strip switch lets you increase the primary current from the dash whenever extra-hi-performance is needed. -Mike |
Re: Mallory Ignition Parts
I also cracked open my NOS in the box Chevy Rev-Pol set-up complete with Street/Strip switch and read the instructions. They don't talk alot about what the switch actually does but does make WARNING to NEVER operate the system in the "STRIP" poition under normal driving conditions. LOL.

Re: Mallory Ignition Parts
Good stuff Mike! That's a lot more info than I had with the Rev Pol transformer. It also sounds like there are no diferences between a Double Life and a Rev Pol distributor? Maybe you can clarify that a little better since you have an NOS Rev Pol distributor?
Good info! Thanks Jed |
Re: Mallory Ignition Parts
Jed - the one big diff betw dbl life and rev/pol dizzys is the latter has TWO condensers - one supporting each set of points separately (the dbl life has one condenser for both sets of points). So, I think you can send a hotter spark (twice as much?) to the spark plugs with a rev/pol dizzy.
|
Re: Mallory Ignition Parts
Sam, I have no clue on that one. [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] The schematics show the dizzy as having only one condenser???? And the replacement parts list show only one condenser too, but if there were two, I'm sure they would be the same part number. So... maybe Mike can clarify if the RevPol dizzy had two condensers? I know I'm stumped.
|
Re: Mallory Ignition Parts
Jed,
I have an NOS HP 310 Rev/Pol dizzy with two condensers. I don't have a picture available. This type is designed to have two independent circuits. With the rev/pol double condenser, each condenser is only in circuit with one of the condensers vs with the double life (single condenser) one condenser feeds both points (breakers). |
Re: Mallory Ignition Parts
Ugh! I was afraid of that Sam! Are you going to the show this week?
|
Re: Mallory Ignition Parts
Yes - I will be there with BELLS! [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
|
Re: Mallory Ignition Parts
the double life name was from each set of points working half the time so they lasted twice as long
the Rev Pol name was for reverse polarity that was used in their special design coil. The rev pol system would give a hotter spark that they claim was like a magneto |
Re: Mallory Ignition Parts
Sweet!! I can't wait to meet you. I will bring some of my toys with when I come out with bbbenny.
