hot coil

[WIMPUS]

Hi all,

My friend has trouble with his TR6 again today.
Brand new coil didn't want to work good and only a small spark  :o
So got mine out the boot and strapped it on the old one.
it worked very well, when we came back home 'my' coil was also a bit hot ..

As the coil is also original at the same place on a GT6 i wanted to ask it here.
So what to do about it ?

Thought about a heat shield and put some spacers between the mounting & engine block..  ::)

Any thoughts ?  :)

First check its a non ballasted coil,3 ohm-non ballasted ignition.1.5 ohms ballasted.

1.5 ohm coil on a non ballasted ignition will cook it.

General heat from the block issue..i mounted mine on the bulkhaed next to the battery.

Is that just measuring on the + and - side , with every wire attached ?  :)
(never measured it ! )

Previous coil was also a regular 12v one i believe .
If was after a good 2 hour drive it did that.
Also friday the car behave strange & it was also very warm that day.
At the evening when it was colder the car worked great !

Even today after my spare was installed he didn't have problems and running better then before !
So my bet is on the heat from the engine ..

Our village garage sorted the problem out on a TR6 by mounting the coil on the inner wing. As far as I know the chap has had no more problems with a hot and subsequently failing coil.
