Replacement Ignition Coil
The replacement ignition coil sold by Model A parts suppliers is a Standard Motor Products UC14T.
http://ecatalog.smpcorp.com/STD/#/ve...m/UC14T?type=s Does anyone have the output voltage spec for this coil?

Re: Replacement Ignition Coil
I agree with Bob-A, but be sure to order the epoxy filled coil.
Epoxy 1.5 ohm black coil = PN 40111 Epoxy 3.0 ohm black coil = PN 40611

Re: Replacement Ignition Coil
6V System
High-voltage output numbers are inconsistent on this forum. I seek the best 6V replacement coil which has the highest output voltage (highest turns ratio). 12V System 40611 Pertronix coils made in China have been recalled because they fail under load. There is another 40611 made in Mexico. There is also a report that some boxes have the wrong part number. What you actually get in the box is a mystery. I bought a Bosch 00012 and it runs really well.

Re: Replacement Ignition Coil
Sorry Bob Bidonde, That hasn't been my experience With the Flame thrower coil .Do you actually have any experience at all with the 40611 coil . It wouldn't matter to me where it was made if it is good . Mine have all been made in Mexico . The 40611 coil that I installed on my roadster has performed flawlessly for the past 12 years . If you can't use it don't try it .

Re: Replacement Ignition Coil
I use an oil filled 1.5 Ω Pertronix Coil in my 6v Town Sedan. I do mount the coil with the high voltage terminal pointing up.

Re: Replacement Ignition Coil
Hi Purdy! Yes, I have a 40611 Flame Thrower, but it failed so I replaced it with a Bosch 00012 (Blue Coil).

Re: Replacement Ignition Coil
A lot of "thanks for the heads up" on the v8 forum but not much in the voltage (6v) or the output. Is it 40,000 or what? I would like to know if they are reliable, is the voltage for our 6v cars, and is the output 40,000 or so? Where do you buy them? I am guessing that the 1.5 ohm is for our 6v systems.

Re: Replacement Ignition Coil
Bob: we use Bosch like yours though turned terminals up as in post 8 for oil filled. We have an older tar filled (or whatever medium) 3ohm Bosch (German made) that works well also. The newer ones are supposedly made in Brazil. The oil filled coil we tried gets hot to the touch.

Re: Replacement Ignition Coil
Some have claimed that the epoxy filled flame thrower coils get too hot to touch . I have had no such problem with mine . I could use either the epoxy or oil filled version as long as they are mounted correctly. A high voltage performance coil will no doubt get warmer than a low voltage coil but not that hot . The epoxy version was recommended so I use it . No problems in 12 years .I can grab and hold mine with no discomfort . If others are having problems with the flamethrewer coil , there is no telling what their problem may be . A lot of people use them with results the same as mine .

Re: Replacement Ignition Coil
Our 12 volt new oil filled gets quite hot but not so much that one can't grasp it. It is cooler than the distributor housing on a warmed engine for reference. The STD UCT coils are made in China. We have also a new UCT15 with internal resistor that measures 4.4 ohms across the primary and 8100 at the secondary.

To test coil output, try a "Lisle #20700 Spark Tester". Or, go to a shop with a scope, hook it up and pull a plug wire off and watch the screen. |

Re: Replacement Ignition Coil
I'm not sure if my original coil is reliable, as I'm still testing it. It's only been in use for 90 years.
