    hi

    I have changed my 3.5v8 back to points . I need help to set the dwell angle. one guy says he has probably chucked the meter or whatever out and another down the road 5mins away isnt bothering . landrover specialist .He can basically pick and chose what he wants to do.

    he offered the tool but would rather he just did it. supposedly a 5min job aye but easy said if you have done it before.

    Any help would be appreciated
     
  2. If you don't have access to a dwell meter, just set the gap with feeler gauges.

    Dwell angle is only a more advanced way of setting points gap. When you set a gap it's dimension provides an open period or dwell angle. Using a dwell meter can make allowances for shaft wear or differences.

    It's not rocket science and many cheap automotive multi meters can measure dwell angle

    15 thou points gap or 25 degrees on the dwell meter

    cheers everyone.

    where is the multi meter connected?
     
  6. If it has a dwell function, it gets connected across the points.

    dwell is better but if the rotor arm bearings haven't any wear in them feeler gauges are ok

    hi

    Just annoying as I just want to get it running and drive about a bit nothing fancy for all I will use it tbh. it's not as if I am expecting people to do it for nothing.

    She is sitting mot'd aswell.
     
  9. So just set a 15 thou gap and go and drive it then!

    Back in the day we set them by feeler gauge and then checked the dwell on the crypton when running.

    I never bothered with feeler gauges on the old P6 distributors, just eyeballed the gap then adjusted the dwell when running. Depending on the meter you are using attach the black or negative lead to earth the red or positive loead to the coil negative (seems wrong but isn’t)

    If you just want to get it running dont get too hung up on dwell for the moment and set the points to the correct gap. Dwell is important on a V8 because the coil saturation point is so small but it will still run ok at lower rpms, come back to the dwell at a later date.

    Ahem, you changed it back to points, I assume for reliability or traditionality purposes, but can’t drive it because you don’t know how to set them? :laughing:

    YouTube is your friend. :thumbup:

    hi

    Thanks. It had luminition in it when i bought with it and it failed age probably . i bought a new kit again and it didn't seem to last that long.

    So for all I am wanting to run it I don't want to spend £200 on another kit.

    I have been having a hunt on you tube.

    they boy I have got tp do it has basically done half a job
     
  16. An electronic ignigion kit it £35 or so. You don't need to spend £200. If you don't have feeler gauges, even a bit of thin card will do at a pinch.

    ok . if I changed ike for like that was the price.
     
  18. If you have swapped over to points, then it is highly likely that you will need to reset the timing after the points gap. If you don't feel able, why not get a mobile mechanic to come and do it?

    Have you change the coil out at anytime? you need the correct or matching one, I think 12v 1.5 ohm from memory or it will cook the electronic units, don't ask me how I know :whistle:

    Bad connections on the Lumenition connector plugs gave me intermittent running problems on one of mine, I think they were unsealed Amp plugs.
