|
|
I know the 6v/12v discussion is regularly revisited here, so I'm not going to flog that. However, can anybody advise me on what options I have to convert my contact/points to an electronic contactless ignition system in my 6 volt 1956 Ford Pop 103E?
Useful suggestions appreciated |

Maplin sell a kit for less than £10, its designed for 12v but by changing a couple of resitors (in the instructions and cost about 20p) it will work on 6v systems.

It dosn't replace the points, they are still used but now only as a switch carrying very low currents, the condenser is effectivly redundant but can be left in place. The big advantage it gives is the speed of the coil field collapse, better spark and allows you to open the plug gap up a tad.

Thanks Dave, looks like a possible option, however I'm positive earth and this unit is for negative earth only. D'oh. |

The Maplins Velleman kit is excellent - building is easy and it works well. I've several spare ones lying about plus one is running the ignition with a coil on my Sunbeam via the magneto points and distributor head. I carry a coil another built kit and some wire in the Alvis in case of Magneto failure.
There are not that easy to box however - the mounting stud is live. I have fitted the Sunbeam one behind and on the wooden dashboard.
Possibly can be used on postive earth by suitable wiring and mounting but I can't say sorry - mine are all negative earth. _________________ Jonathan Butler

Do you get a circuit diagram with it and if you do could one of you scan it and post it? _________________ 1936 Morris 8 Series 1

Nic
I've got a spare instructions and circuit somewhere - I'll pop a copy in the post - its a simple circuit anyway all discrete components. I could not be bothered to roll my own so bought a few kits in a Maplin sale.
PM me your address and I'll send. _________________ Jonathan Butler

So, thanks for the input gents, but I still don't have any viable slutions.
Can anybody advise me on what options I have to convert my contact/points to an electronic contactless ignition system in my 6 volt 1956 Ford Pop 103E, which has positive earth? |

Mello,
There's no reason why you have to keep the car positive earth. You can switch it to negative earth easily and gain the benefits that you are looking for. All that's required is to repolarise the dynamo and reverse the coil connections. There are instructions here on previous posts. Just search on re-polarising or 'flashing a dynamo'. Get the Maplin ignition kit and you can do it all when you install it.
