do ignition coils get very hot?

[KentMoney]

I ask this question because I plan to make an electronics box for my rephased '81 and I would like both ignition coils to sit inside it.

Do ignition coils need to be exposed to air say like the reg/rec? Will I have to worry about overheating if I place it in a metal electronics box?


Thanks!

I would not, but thats just me... I've never burned up a coil that had good airflow to it...

Pamcopete has always recommended the core laminations of an ignition coil be in contact with the frame as a heat sink. Some coils run hotter than others, so I guess there is no simple answer.

With my Accel coil, I have never needed to have the core in contact with the frame. However, I keep my coil out in the airflow, and it never gets hot after a long ride.

Every coil heats a certain amount, and putting it in an enclosure is just the wrong thing to do.

DAMNIT. Well, OK, thanks for the info. Definitely good to know.

I guess back to the drawing board for this damn thing. I need to let it get a draft somehow...


why do mikes coils have to be bright green?! black would have been ideal...

I'm thinking the Chinese like that color, lol.

Lots of people have painted the Dyna coils with no problems. Give it a quick Google search and you'll find quite a few results.
