Bought one just like it in 1980 for a Mustang I owned while in the Corps. Worked great. As I remember, they require a resistor block to work properly.
I ran one into the early 70's, along with an early Mallory electronic ignition. See that red cap on the top? That's where you can refill it with dielectric oil if it leaks out, which some of them had the habit of doing if they were not mounted with the cap at the top. They also would tend to leak around the secondary wire terminal.
If it still works you must run a ballast resistor with it. I always thought they were the coolest looking coils
How can I test it? And where do I find an early 60s ballast resistor(no late model stuff)? I am sparky challenged!
I put a few hundred thousand miles on the one I had till it crashed.They work great.The also made an electronic ignition version, check the label.
I bought recently a couple of those. There was even a 6V Voltmaster coil. Some of ém say Magspark. On one I have the metal label wich said "Voltmaster" flew of and under it you could read "Magspark" in the plastik housing. Is there a difference between RevPoint Magspark or Voltmaster coils? I guess they cannot be interchangend?
The "Magspark" coils were intended to be used with either a Mallory Magspark distributor, or a stock distributor with a Magspark conversion kit. The "Voltmaster" coils were intended to be used with just about any distributor.
It is shown in Honest Charlie's 10th annual catalog in 1958. They came with some very cool looking ballast resistors mounted right on the top of the coil. They are round with a steel cover. You could probably use a generic ballast resistor but the old Mallory's resistors are cool looking if you like old hot rod parts.
Tommy- If I get another of these, could I un them with my Spaulding Flamethrower, the one that was yours years ago?
Edit this is from a 1954 Newhouse catalog. If I've got it right a Mag Spark coil has 2 windings inside that Mallory used to do the same thing that Spalding did with 2 separate coils. Each set of points only energized one side of the coil at a time. If I'm right, you would only use one side of each of these coils with the secondary wire from each going to each side of the Spalding. I'm assuming you just want this coil for its looks. I'm no Mallory expert. I'd check with Bubba to see what components would work together including ballast resistors.
Yep, I love the look of old stuff, otherwise I use some ugly EFI engine! I will check with Bubba for some info.
Looks like a CRACKED coil. Isn't that a crack running from under the price tag to the lower right corner?
shake it and listen for the oil sloshing around inside. if you don't here any it probably leaked out the crack (if that is what the line is). if no oil inside, seal the crack, carefully unbolt top and separate from the bottom slightly (don't remove). fill the case about 3/4 full with marvel mystery oil . put it back togethr and try it. i run one on my 283 and have had good luck with it.
Is it marked 6V or 12V. I have a 6V one with the round ballast resistors as in the catalog picture. I think mine has a sticker that makes me think it's 6V. If it's 6V it's just showcase material.
My car has run a Voltmaster coil forever. I replaced it with this NOS one a couple of years ago. This one said "For Electronic Ignition" on it but it still worked for points. This week I switched my Mallory dual point over to Pertronix. Of course they want you to run one of their coils. So what I did was mount the Pertronix coil under the dash. I left the Voltmaster on the firewall but I gutted it and ran the coil wire into it and out the back through the firewall. BTW,You can still get the Mallory #700 ballast resistor from Jegs. http://www.jegs.com/i/Mallory/650/700/10002/-1
