Electronic ignition.

Hello all,

in view of the popularity of fitting after market electronic ignition modules, the following thread from another forum makes interesting reading:-http://club.triumph.org.uk/cgi-bin/foru ... -new/#num9

Thanks Alec ! I had lost my link to Club Triumph forum!! Your link has put me back in touch........Another forum !!
Their views pretty much follow my feelings about leccy ignition - although my TR7 came with Pertronix, which appears to work v well - and I have no intention of changing it. But I do carry a complete spare points dizzy with me at all times.........
As for the ACR generating 'spikes' - I seriously doubt it unless there are bad connections - the generated voltage is being 'sunk' into the battery at all times.

Hello BMCE,

electricity is a strange animal, for instance, I read a peper on fault currents with relationship to HRC fuses and in the analysis it referred to the D.C. component which altered the current sine wave assymetrically. I didn't understand it or where this D.C. came from in an A.C. system under severe fault conditions?

I would guess at poor brush connection on the slip ring as being the source, but whether it is typical I don't know, however, electronic components should have adequate inbuilt protection for a 'dirty' power source.

That is why I never fit electronic ignition to any of my Minors - reliabillity! I have heard far too many stores of catastrophic and sudden electronic ignition failure.

If this happens you will have to be towed home, unless you can re-fit points, condensor and rotor arm at the side of the road, in which case you might as well stick with the standard ignition!

Precisely!

I fail to see the sense in the rush for electronic ignition.......It certainly doesn't give improved performance or economy, and it's hardly arduous to check/set points gap once per year!

and what if you end up changing points and condensor around 4 times a year?

Hello delerie,

"and what if you end up changing points and condensor around 4 times a year?"

Why should you?

just seems that in the 2 or so years i've had the car, i've changed the points etc almost 10 times i reckon. i know they are a consumable, but thats surely too many?

[bmcecosse]

Unless you are doing fantastic mileage......... My points etc are at least 10 years old and still going strong.

ok. i know the new ones are rubbish, where's the best place to find the decent old stock?

[Neil MG]

They come up from time to time on eBay

Aupickup is selling some..

It sounds like that you're running a coil that requires a ballast resistor, w/out the resistor.
Or there is some other problem that is causing the points to fail prematurely, points should last 10,000 miles or more.

I burnt out 2 coils with electronic ignition, ballast resister fitted then had no problems.
On my new car have points, think I keep it that way.
