ballast resistor questions

[josh_t]

I have a 76 b210 with points still on it, so i know its necessary for a ballast resistor. I want to upgrade to a matchbox dizzy. I am using a pertronix flamethrower 1.5 ohm coil. Can i use this coil with the matchbox without a ballast resistor?

The Manufacturer would know if its made to run off staraight 12-14volts.

Another way to know is run it W/O a ballast and feel if it gets HOT!!!!!!!

 

The matchbox Later A series dizzys used a .7 ohm coil. so really your not going to get the full spark but it should still work if the coil is made to run off the higher amps.

 

you could still run the 1.5 ohm coil and ballast also if you want. just hook B of matchbox to the most 12volt point. this is usually the + side of the ballast resisitor.

C to - side coil

 

 

remember just because it says FLAMETHROWER dont mean its going to make your car faster

i would rather not use the ballast and coil together since that is about 4 times more resistance than is necessary. i'm sure that doesnt help performance any. and i know it wont make it faster, but a friend gave it to me so why not use it if possible? it at least looks nicer than the nissan coil. lol

(MIKE) will tell you how to run without a resistor

 

but isn't that flamethrower 1.5 for v8's?

I would take a reliable 30 or 40 year old Nissan coil any day over something that is designed to look nice on a shelf in a parts store.

it sure is lol. my friend had it in his 70 mustang with a 302. but he said it wouldn't run with it. it worked fine in mine.

a good article on coils (specifically the bosch blue)

anyway, seems another ratsuner recently asked a similar question

maybe we need an ignition sticky?

this is the sorta thing you forget about if you're not a tech

yea sorry bout that. i think i might have stumbled over some other useful ones that are close enough to this one. i'll check tha article later

Just go to your local Pick-n-Pull and get a genuine Nissan (hitachi/hanshin) coil for $5 that is for the matchbox.

flamethrower is for all, not just V-8s, had them on my 1975 celica, 1971 Datsun and 65 Mustang V-8..if you do get these just aske pertronix if the ballast resistor is necessary, theys hould know.

Pertronix Flame-Thrower coil comes in 1.5 ohm and 3.0 ohm versions. Hopefully it will say on the label.

 

Not to be confused with Flame-Thrower II, Flame-Thrower III, Flame-Thrower HC or Flame-Thrower HV coils.

 

Technically, pertronix sells a different coil for V8 and 4/6 cylinder engines. They also sell a low-energy electronic ignition, though most are high-energy.

 

So bottom line, best to ask Pertronix.

ok. i know mine is 1.5 i'll just see what they say about running it without a ballast. my guess would be that its ok but my guess isnt always best.
