Fitting Newtronic Electronic Ignition

[rulloyd]

Does anybody have any experience of fitting a Newtronic Electronic ignition from the 1980's please? I'm refitting it to my car after a lot of years and I can't remember how it was wired.  A wiring diagram or instructions would be ideal please?  There's no model number written anywhere on it.

Any advice much appreciated!  Rich

Hello 

         I have a diagram somewhere I will look tomorrow

Brilliant!  Thank you Roger.

You could download the instructions from their website recently.

i have them on 4 of my cars.

Get it wrong and the big transistor packs up.

BTDT. 😞

Perfect thank you. 😉😉  Stand down Roger I think I have what I need.  Thank you both.

To tell you the truth, when dismantling the ignition system in a hurry, I didn't want to disrupt the dizzy so I cut the red cable between the dizzy and the control unit, planning to rejoin it.   Only then did I realise it had 6 wires inside.  Planning to solder them all up but if anybody has the main red cable (which I think is joined to the optical unit) and is happy to part with it, do please let me know! (they are very small wires!).

Or perhaps, can anybody recommend a small waterproof connector for 6 very small wires...

All assistance much appreciated.

It is like defusing a bomb.... What ever you do, don't cut the red wire!

I thunk you may need to get the soldering iron out as I don't think the optical sensor is likely to be available.

Hello  I found mine and I have a unit I removed from our Spitfire to fit megajolt then microsquirt.

If you want it you can have it for a reasonable price

Ah ha, that could well be my best option thank you.  Can you message me a price please?  Is it likely to be the same sensor unit though (4cylinder vs 6)? 

One of the reasons I cut the wire was to avoid disrupting the set up in the dizzy do you have the instructions for that?! (not on the site Scrapman kindly forwarded or the manufacturers site as far as I can see).

Many thanks

Hello Rich

                  I think you will find the sensor is the same they just use a 4 or 6 blade vane.

I will dig it out this afternoon and the instructions and message you later

Roger

ps what car is it going on?

 

[rulloyd]

Hi Roger.  A GT6 Mk2.

Thank you!

[rogerguzzi]

Hello Rich

                 Here are the instructions and photo of the unit

Roger

ps pm,d you

[rulloyd]

Cool I'll have it thanks Roger.  Also gives me a spare control unit just in case. 👍

just seen this thread. nothing to add other than I've been running one of those since the 80's and never missed a beat.

Good to know.   The conclusion to my story is that sadly the box that Roger kindly sold me actually had a different attachment for the lamp in the dizzy which could not be modified so I couldn’t use it.  I had to resort to soldering my cable (last night by coincidence).  The instructions show that the unit is compatible with 4 or 6 cylinder (just by changing the slotted disc in the dizzy) but only for compatible dizzys I guess.  I presume the spit (from which it came) is a different distributor.  😩😩

The actual control unit looks identical and will be useful as a spare.

Anyway, hope to install the fixed unit at the weekend and start the rebuilt engine - exciting times 👍👍

Excellent unit, I had one fitted to my herald estate for at least 15 years. It never missed a beat, herald now sold. I have had other units fitted to my other triumphs,  all failed. 

Now given up on electronic ignitions and gone back to points and condensor.

Hello Rich 

                That is a shame but Spitty has Luas and I suppose you are Delco? We never thought of that goodness knows why Triumph used both?

Still you could sell it on as it should be ok on a Lucas system and I think someone would like it for the same sort of price!

If anyone needs extra vanes / triggers I have three or four of them in a drawer... the unit is long gone but these were left behind.

[rulloyd]

Sorry Colin, when you say vanes / triggers?

I would assume he means the plastic propeller-like thing that fits on the shaft?

Yep, those guys. I have three in a drawer, all variations of 4-cylinder if any use to anyone.

[rulloyd]

Ah ha.  Thank you.

Personally I’m ok thanks. 👍👍
