Hello everyone,
As I read in the instruction manual and as advised by Velleman, the kit can’t be built in a complete closed enclosure, so with the heat sink covered, or overheating might occur.
However, transistor ignition has been tested for decades and many people drive around with transistor ignitions, also the Velleman kit, with all the elements built in a complete closed enclosure, the heat sink covered, without any problems at all for many, many years.
The reason why I am considering enclosing it completely is because protecting it against the environment suddenly becomes very easy and the looks are far better.
In a post I read that if everything is installed correctly and the ignition circuit and coil are fine, the sink hardly heats at all which confirms my idea that covering all the elements up won’t do any harm.
From the past experiences I am wondering why the open air contact of the sink is stated as a necessity while many, many years of testing without problems have proven that covering it up is ok?
Could anyone comment on this?
