I have an annoying problem.. the restoration wont charge. The charge light stays on despite checking the dynamo, the wiring Etc. Tonight I wired up the field core wire to the dynamo wire and attatched a test light. There was no light. This points out the dynamo is not charging although I tested it last year and all was working. Anyone have any ideas I'm beginning to get fed up with the bloody thing.  |

Had plenty of dramas with mine soon after I got it back on the road . Same problem so I put a new dynamo on it , and it failed after about a month . I got a replacement fitted it then the control box stuck one day when I switched the car off and nearly burnt out the wiring luckily I pulled the wires off the dynamo just as the control box tried to turn it into an electric motor . Since I fitted the new control box it has been alright . Even after not being used for a while I have not had to charge the battery.
My advice is fit a new dynamo and control box , then it is job done. I wasted a lot of time stripping the original dynamo which fixed it for a short while , I also adjusted control box which also improved things , but not for long . I then realised that it was a false economy trying to keep electrical parts going which could be 40 years or so old. The control box I got looked just like the original and claimed to be British made .

Thanks tod, I have a new regulator box and also tried 2 others. The dynamo is original but rebuilt with new brushes. It was ok when tested but that was last year. I really could do with an electrical guru so may call on a mate. it cant be much as there is bugger all to them  |

I have a Lucas manual that shows how to do a complete test on a dynamo and pinpoint the exact cause of the problem . I could scan it and email it to you if it helps.

Your Dynamo is probably needing re polarised if it hasn't been used for a while.

If its been sitting around for a year or so the brushes may be corroded and stuck might be worth peering inside, just a thought as its happened to us with dynamo's stored in damp places

you may be right dave -The garage although not damp is far from perfect. The dyno was working last year so I will check again. |
