David J Posted October 7, 2018 Share Posted October 7, 2018 I am looking for a splitdorf coil box that would be used on a 1910 four cylinder. In particular I am working on an IHC J-30. It was a dash mount as would be expected. Any ideas? Thanks Link to comment Share on other sites More sharing options...

David J Posted October 10, 2018 Author Share Posted October 10, 2018 This is the closest guess that I have. this is a different J-30 but we don't know for sure if it is original. Thanks for the help Link to comment Share on other sites More sharing options...

Layden B Posted October 10, 2018 Share Posted October 10, 2018 David J, Your pictured box is a low tension magneto switch/coil. The number of cylinders is determined by the magneto. A 4 cylinder coil box would have 4 coils in it and a timer to match on the engine. old car fan, The coil on the right in your picture has 2 high tension terminals on the bottom, it is for a 2 cylinder engine.

David J Posted October 10, 2018 Author Share Posted October 10, 2018 Being an old Model T man this is all new to me. I have the splitdorf magneto (much different that the magnetos I am used to in the "T" transmission) still mounted beside the engine. I am more used to the coil box arrangement on my '15 and how those coils work. I know that the box pictured is in fact on a J-30 and thus is a 4 cylinder car. I am not sure however how it is interconnected. The problem is that there are just not a lot of the J-30s around to compare. Those one can find by a search have been restored without reference to the original specs. I am sure open to some place I can read up on how these systems work. My wife's grandfather, wired in a modern coil so he could drive the car around and ran it off a battery so I don't have a lot to go on. My car is a early-mid year 1910 (car #47) Thanks Link to comment Share on other sites More sharing options...
Layden B Posted October 11, 2018 Share Posted October 11, 2018 Picture of your mag on the car? Link to comment Share on other sites More sharing options...
David J Posted October 17, 2018 Author Share Posted October 17, 2018 I am sorry for the slow response. I have been out of time. It appears that my mag is a model D and thus would have a non-vibrating type of box Link to comment Share on other sites More sharing options...
