Ah. I didn't realise the transistor couldn't handle full battery voltage and coil current. I thought as long as it has a heat sink and kept away from external heat sources it would manage the slightly higher current with no problems. We live and learn.

Dave999, the education sector sooo misses you!
I suspect you don't miss it

cheers Ade, I’m ok with it getting hot, I mentioned it so we understand that is it working and not just there for show

cheers Rob, I have a PN8202 already relocated vertical to the inner fender below the washer bottle

cheers Dave, I will leave well alone then, the car is running fine, many thanks for your most elaborate answer, more a small book than an answer

no probs fellas

its just the usual brain dump

dave yes todays transistors can probably handle those currents no problem

ceramic and semiconductor tech has come a long way...

FBOs igntion is supposed to work well at 12-15 volts no balast and their own coil so they obviouly put some time in there.


steve a magneto would be fun but much better when crank driven...
the weight of the internals and the fact they are hard to turn kinda dictates not using them on a standard cam driven screw gear and in some cases plastic drive gear for street kinda stuff

they worked quite well on VW aircooled Drag race engines cos you could do away with the alternator and fan and cliam back something daft like 33% of your power that the fan was eating up. no good for the street mind run it longer than a few minutes and it would overheat the oil

Look good don't it?
I'm gonna get one anyhow and check it out Rob/Stu

Did you source one Ade ?

Well I thought I'd got it on the way but me ginge never done it

Gonna do it me self this weekend.... why? You want one? No sweat mate if you're interested I'll add it on, or if I get enough interest I may phone em and see if I can't get some discount and buy a dozen or so

If it aint silly money then I'll have one (if no hassle for ya).
Regular orange box ~£50 I think - so assume this will be sub £100 ?
Let me know how much will drop money in.

the price is on the link Morgan ...

Bananarama! I missed that. $190 ?!?! errr - dont worry about it Ade, as they say on Dragons Den "I'm out". Sorry about that.

Will wait and see if price comes down (like half!) but otherwise its spare orangebox in the boot I think !!
