Electronic Ignition

[Parkerscottages]

I have just fitted a complete Power Spark dizzy, and wondering what a typical advance setting would be. It seems to want to be around 7degrees before TDC

the car is fitted with a fast road cam which may have some bearing

any thoughts welcome

tks

On a flat road, engine fully warmed-up, drive to 30mph & select direct top gear. Floor throttle, if you hear pre-ignition:retard if you dont hear pre-ignition: advance. Correct setting is at the point where the pre-ignition just stops. This method takes all fuel/cam/wear/altitude factors into account.

If been told Power Spark it is a copy of the Pertonix Ignitor, I used the Power Spark some years and had sometimes not expainable ignition faults.

Now I use Pertronix and the German distributor clearly demands not to keep the ignition ON for longer as necessarily needed (1 minute) without the engine running.

In this case about 4 A current ( own measurement) constantly flows through that tiny electric device to ground and causes damages.

Indeed with the Power Spark I did not know this, shure with several troubles I had the ignition on for a longer time and this could explain my ignition problems.

(shure, not the aswer to your question, but perhaps the answer to something you never have to ask...)

I was lead to believe that Powerspark was an offshoot of Accuspark (they look the same). Pertronix looks different.

Sorry, it is a copy of the idea, indeed the looks some kind of different,

but it's more or less a simple electronic switch triggered by a magnet ring - without the safety feature "continious current switch off".

If you buy a more expencive "Pertronix Ignitor 2" you got this feature.

Hi Dave, that's a great and simple test, I will give it a go,
