Well folks the Rav is back in the doldrums.
Mrs P had a couple of days holiday so the Rav hadn't been used for four days so decided to go out in it yesterday and the battery was flat so thought I would put a new one on.
Phoned the local Halfords who had one in stock a Yuasa, great I thought. Tried fitting it and the lugs were too small even with the sleeves. So phoned them back and the young chap said sounds like you've got the wrong one as we have two Yuasas for your Rav. Took it back swapped it over tried fitting it and the terminals were the opposite way round and the positive lead wouldn't go on. Took it back got refund so Mrs P said she'll phone the AA who came out and diagnosed that the Alternator was knackered and battery needs replacing.
So is there anything else to look out for while changing the alternator, will a recon one be ok to fit??

Recon one with a warranty would be fine. Battery may recover when new alternator fitted and actually charges it, albeit you will need a bump start at first go......lol.....! If battery more than five years auld, send it to Dan Flynn.

I agree with Kev. Your current battery may simply have not been getting adequate charge from the duff alternator. Worth renewing the alternator first and see how the battery does for a while. Coming into the better weather even if it's a bit past it's best it may perform OK until the winter chill returns. Then you can replace the battery.

Thanks both, but more problems now. I have had the battery on charge all day today so we could get it in the garage tonight. So Mrs P came home i put the battery on and the Rav fired up staright away, however t are there are no dash lights no indicators, no rear lights, front lights work, and that's all we checked tonight, apart from Mrs P said she could smell burning. Anyhoo the Rav is in the garage now and I have disconnected the battery and will have a better look tomorrow at what I haven't a clue. But I remembered THIS post by Oxo which made me think then that the second battery we got from Halfords yesterday was the opposite way round to the first, by which I mean the back of the battery was facing into the engine so the leads would be on the correct terminals and I did connect it and got a spark from the positive lead which I was told by the bloke at Halfords would be ok. Is this the case do you think or has it caused the same problems as what Oxo has/had?? I wondered why the AA bloke asked me what the mileage was when he was sitting inside with the engine running?? |

If the battery was connected the wrong way round then I would guess that one or more of the fusable links (& maybe some of the fuses) have blown. The fusable links and some fuses are contained in the black fuse box under the bonnet near the N/S suspension turret. The other fuses are in the fuse box behind the coin box in the lower driver's side dashboard.
You will have to check the fusable links first to see which, if any, have blown and then the fuses if you still have some circuits not working.
I am no auto-spark but I would guess that some of the links have gone and once you identify which ones, you can replace them and get the car up and running again.👍👍

Sorry I don't think I was clear about my explanation above?? I connected both Halfords batterys the right way + to +, - to - but the second battery was the opposite way round when I came to fit it to the first one. Instead of the neg connection been by the wing, with the battery the correct way round I had to turn the battery round so the battery was then back to front if you see what I mean? I tried connecting the positive cable and got the spark and that's all I did before realising it wasn't going to fit so took it off. The car was only started after using jump leads and when the AA bloke came out and used the booster pack. So as I say it looks like the electrical fault occurred some time then but the original battery was fitted?? Would that spark from the pos lead have been enough to cause this problem?? |

Paul, whatever happened, it sounds like the system has protected itself by burning out one or more fusible links and fuses at some point. Best to check it through methodically :yes:

Paul , mine has a fuseable link as part of the positive lead where it bolts to the battery, have a look there.

Jase I have been and had a look and there is a flatish black box attached to the positive lead unlike in Oxos case, but how do I get it open?? Also had a quick look in the fuse box in the engine bay on the passenger side and nothing looks untoward in there but all needs testing I guess? |

Also had a quick look in the fuse box in the engine bay on the passenger side and nothing looks untoward in there but all needs testing I guess? I would have thought that if the car starts and the headlights work then the battery leads and clamps should be ok. The other circuits that aren't working need to have their fusable links and fuses checked. Unless there has been a massive overload, there is unlikely to be any physical evidence apparent on the fuses or links themselves. You will need to check across the links or fuses with a multimeter or a test lamp to determine if there is a complete circuit. If not then replace the link or the fuse |

If not then replace the link or the fuse My mechy mate popped in this afternoon and he had a look saying that the alternator has packed up and not to mess with any fuses until the new alternator has been fitted as this could be the cause of the other leccy failure so will leave alone until then :TU: |

Paul , on mine it looks like this..  And if you carefully prise the black body apart it looks like this inside.   you can see where I made a temporary repair by soldering the burnt track which lasted until a replacement was sourced and fitted at about £50 if I remember correctly.. |
