Any ideas? hey how about becoming a member then........? your battery is flat. it will only recharge itself if you are running it . if it has gone flat in a week just sitting there i'd say your due a new battery. |

Right, just charged battery, car started up, swapped the oil light around with the ignition light and sussed out that the bulbs gone.
But then the ignition light wouldn't go off!
Father tells me that this means that the battery is still not charging itself??
Please help! i have no idea!

Not too good on mechanical stuff...  ...but could it be a problem with the alternator?  |

Is the belt at the right tension? The top pulley has shims between the two halves to set the belt. Too loose and it won't charge right. Want me to nip over and have a look sometime? No bother dude, if you want a hand giz a shout ;D

Right i've worked out that the ignition light is working perfectly alright, i just had the wires a bit muddled up but thats all sorted now! I will have a little lookie at the belt later, i think my dad knows how to do that so i should be o.k. on this one! Thanks anyway, i'l let you know how i get on. |

Erm not quite....
Took the fanbelt apart to take the shims out and there wasn't any there!
So that means i can't tighten it, gonna get a new fanbelt tomorrow though and see how it goes

Are the bushes and bearings ok inside the dynamo? Might be worth sticking new bushes in if you can afford it. Hope you're rollin by tuesday night ;D |

Just replaced the fanbelt so shall just have to wait and see if the battery runs flat again!
Haven't looked at the dynamo yet as i haven't got a clue lol
But i will have a little fiddle at some point!

 This was a previous project some years ago now, and that was 6v electrics, isn't it just great fun . My first piece of wisdom is get a starting handle ;D thats a real plus with 6v. Seriously check your earthing from the battery to the ground point on the frame, this must be spotless and no rust, next check any grounding straps on the vehicle for the same. You need twice as many amps at 6v, as you do at 12v to do the same job, so as a result if you have bad earths you lose a lot in voltage drop. Next battery on you vehicle needs to at leased match the required amp-age to start the engine, in cold weather. For example the wartime recommendation for the Willy's jeep battery was 112 Ah, I had 120Ah on mine and it was still a struggle to get the 2 litre engine to turn over and fire on the starter in cold weather, and the battery would also slowly discharge if left for any length of time. All the above can affect battery recharge level, plus a Dynamo does not recharge a battery at the same rate as an alternator, it takes much longer, and so on short runs the dynamo is always trying to play catch up with the battery. If you have a Voltage regulator unit fitted this can cause the battery to discharge back through the dynamo if its not set up correctly, they are also temperature sensitive and so the battery recharge time is increased do to reduced charging rate during cold weather. Like I said,don't you just love 6 VOLT, who thought that would be a good idea ? |

I think its a flat battery!
