When I started using electronic ignitions I did something similar only the boxes were a little smaller. Inside I have the ignition module with a small 4 amp sealed battery. For terminals I made my own mini banana type plugs (1/8 dia.). I have 5 of them, 3 for the Hall sensor or use 2 of them when I'm using points, a separate ground and one for the HT (spark) lead. To keep the battery from banging around inside the box I cut a piece of dense rubber foam and wedged it between the battery and the end of the box. The top cover is hinged and has a mini toggle switch for turning the ignition on and off. I also have pilot light (LED) that tells me when the ignition is on. gbritnell
Yeah J, i was thinkin about tabbin up some rechargable cells i have laying around here. I am learning the small IC engines dont need a huge auto type coil. What do you think is a cool scale sized coil, that we can scab outta the rubbish?Paul
