Complete confusion, wiring,firing

Post by Oddjobber23 » Sun Aug 16, 2020 5:46 pm

Hello, I hope someone can help me with a non firing problem. I have a SE6a and it is in need of extensive work as it has been sitting for many years apparently. When I got it the coil and ballast resistor were sitting on the front seat, and the coil had a hole in the side. I decided to buy a new one of each of them, which arrived yesterday. I followed the wiring diagram that has been very helpfully put on this site as much as I could, knowing absolutely nothing about electricity and with the diagram looking as if it was from another planet. It says that the white wire from the ignition goes onto the ballast resistor and a white and yellow go to the coil which I think then goes to the starter. On the other pole goes a black and white, and another to the distributor. The wire to the dizzy is a different colour to the one stated on the diagram, but I assume that does not matter. Anyway to the point, apologies for the winding route but I am trying to give all the info. Again to the point, I see a plus and a minus on the coil and a plus on the resistor but I have no idea which wire goes to the plus on the resistor or to the plus or negative on the coil. The coil I purchased came without the connectors attached and as each pole is the same size I have no way of knowing which goes where.
Can someone help by giving me a tutorial, in idiots language, as to which wire goes to which component and which goes to plus and minus, on each component.
Again my total apologies to the long windedness, if that is even a word, and even if you read this far and call me an idiot I thank you for reading this far.
Thank you, Alan

Hi Alan
Positive on the coil should go to the ballast resistor. And no, you're not an idiot.....wiring diagrams are easy for those that use them regularly. We've all got to start somewhere 😁😁
First thing to check though is what is in the distributor! Take the cap off, if you have points in there, then use the ballast resistor, if it's got an electronic ignition, then we need to know more!
Another useful download here is the owners manual.....it has quite a lot of basic info including a b/w wiring diagram with + and - marked on most items where appropriate.

Alan , I cannot help you , as I am electrically challenged as well . Put a engine in front of me and a good manual and I am ok , not an expert but ok .The issues are often compounded by the fact that our cars are quite old now and have had the electrics " up dated" by previous owners who probably had electrical skills only a little advanced from ours . Please do not apologise , one thing I have learnt from a little time on this forum is that we are all in it together and 99.9 % of members will be happy to help , some of the lads may be coming back from Curbs today so I hope you will get some help soon . Regards . Richard aka Catweazle .

Hi, thanks for all the input I really am most grateful. So the coil positive is the white and yellow, and the positive on the ballast. My dizzy has points and condensor if it helps.
Cheers, Alan

Points and condenser means you should stick to the ballast and coil, I was just pondering that if they had been taken out, someone might have put electronic ignition in!

Alan , I think you may live in Helhoughton , why not give Richard [ Pellvet ? ] a bell as he is the local Sec for the noggin that possibly meets at The Bell Marlingford [ covid issue appreciated ] , his number is on the noggin page . I agree with Peter , nothing like face to face [ or ear to ear ] and it will build up a local knowledge base for those future problems :) Regards Richard .

Thank you so much everybody I am in your debt for all the input. You are quite correct, I am indeed in Helhoughton in sunny North Norfolk. As for contacting Pellvet I have absolutely no idea what you mean by noggin. I am one of those muppets the bumble on regardless and come back to the font of all knowledge Scimitar when I am really stuck. I am beginning to wonder whether I should even bother with it. I sent a mate to look at the car whilst I was in hospital with double pneumonia and he graded it as a worthy subject within my capabilities, and him a mechanic. It arrived and it is basically gutted inside and the outside isn't much better, but I always loved a challenge.
Regards, Alan

Noggin (aka Noggin and Natter) is a meeting of people who like to share their Scimitar-centred troubles over a quiet refreshment.

Hi Alan , sorry to hear about your illness , hope you are on the mend . A noggin is , as far as I am aware , a informal get together of local enthusiasts most have a Scim ,some aspire [ silly s.ds]. They normally happen at a local pub and are very laid back when I have gone . You will meet people from all walks of life ,and I have to say that of all the different car club noggins I have been to over the last 40 years [ I am 64 ] the Scimitar ones are the most kind and welcoming , think of it as GOOGLE with a pint in your hand [ shandy ]. I would not be surprised if some one from your area pops up soon and invites you [covid appreciated]. Come on you Norfolk boys give the man a hand Regards Richard .

I’m not an expert on wiring either, but what I would say is that make sure you have proper connectors fitted. Avoid crimping where possible.

Welcome;
Here's my take on it...
The coil should have a + and a - The - goes to the distributor so that the points can connect the coil to earth.
The + goes to the ballast resistor (via a white/yellow wire)
The other end of the ballast resistor goes to the ignition switch (via a white wire).
This should all work OK and give you sparks at the spark plugs.
In addition, because the starter draws lots of power and the battery voltage usually drops a bit during starting (especially during cold weather), there should be an extra wire putting battery voltage directly onto the coil but only while the ignition switch is turned fully and the starter motor is turning. However, with a good battery you should get sparks even if this wire isn't yet fitted.
Fingers crossed this makes sense and you make some progress..
Good luck !

The Correct type of coil for the Scimitar has Different sized threaded poles. :!:
If you look closely at Peters Artwork you can just make out the size difference.

This means the coil can only be connected one way round, if the Black rubber Ford/Reliant ends are still attached to the ignition wires. :?: that is.

A picture's worth a thousand words. - thanks Peter.
Shows my confusion over the White/Yellow wire so ignore what I said!
