Technical Fiat 500 1.2 Lounge alternator

[jason1966]

Hi,

Fifi broke down and the AA have told me that the alternator has gone.

Anyone got a ballpark figure of how much a garage may charge to replace one?

Also, how do I get the right part number if I decide to do it myself as I have seen a few different models. It does look a bit fiddly with the belt in the way.

TIA

Jason

Wouldn’t have thought it’d be more than a couple of hundred (depending on cost of alternator). If you did want to attempt yourself if you put your reg into either Euro car parts of GSF car parts you should find what you’re after, even if you just use there pictures and dimensions to buy the correct part elsewhere

Does the car have stop start, different ones for with and without though not too great a price difference at about £180, note some are for warm climate?

 

[jason1966]

it is a stop start model. Battery is a bit suspect as well.

Might be more economical to attempt yourself then. If @John202020 said start/stop alternators are £180+, start/stop batteries are always more expensive so expect upwards of £100 i’d of thought, then whatever labor the garage would charge. Could be a hefty bill

 

[John202020]

This could work, but check with seller £110

Pardon our interruption...

Would not bother with a stop start battery
I would however replace the engine earth strap £5

I tested the battery and it had 2.6 volts. Charged and started with jump leads and was 11.6 volts but dropping steadily with nothing on.

Have you tested to see if the voltage still drops on the battery with the leads disconnected as 2.6v seems very low even for a battery that’s completely shot. Sounds like a battery drain situation to me

 

[John202020]

Get a new battery, dare I say a non stop start one, start the car, turn on all the lights and rear screen test the voltage, does the Bluetooth work? New earth strap too

A non-stop/start battery is likely to have a shorter life if used on a stop/start car. However, the battery on the Doblo appears to be a standard battery, and is apparently the original. But, being a wheelchair conversion, it is possible an incorrect battery could have been fitted during its conversion time. Tayna recommend the same battery for that as for the Fabia, at around £97. Almost a bargain.

The only reason I suggest a non ss is I feel most 500's are driven in a manner where its unlikely to ever work, ie 15 ,20 mins to the shops or work?

I have left the battery for over 24 hours and it has stayed on 11.76 volts. The voltage previously dropped after I started the engine and moved the car out of the drive where the engine stopped and would not restart. Good chance it is the alternator then ?

That battery is completely flat it should be well over 12v

12.6v is generally around fully charged


Can't see if you measured the voltage with the engine running or not?

This should really be over 13v to let it charge the battery up

The battery wasnt given time to charge - rain stopped play. I'm hoping to try again when i get home. I will be more thorough with readings.

You must have a MINIMUM of 12.6 volts- 12.8 more desirable!- when running even at idle the system should supply/run at around13.2 and up to 14.0 when revved rather than a multi-meter a proper battery load tester such as a TOPDON will give you more accurate results!, from all thats been said before i do not believe your current battery will recover and be serviceable! without a good known battery you have no way of objectively measuring the alternators performance!- get a good new battery first and then move on to the alternators performance or lack of it if the battery does not solve the problems!.

 

[John202020]

I'd try a new battery first, even if its not this, given its been totally flat, and winter on its way replace it?
Note generally if the alternator is bust the battery light should be on?

And a new engine earth strap,,,

 

[jason1966]

I charged the battery with my other car. The battery was at 12.7 volts.

I started the Fiat without leads attached and the voltage dropped down to ten and wouldnt start.

I re-attached the jump leads and started the car again and the battery did not move above 12.6 volts with the engine running and the jump leads attached with the other car running.

When I removed the jump leads, the engine cut out after about 30 second.

 

[John202020]

The fact the engine stopped after such a short time suggests the battery is knackered a new battery would keep the engine running for at least an hour even with no alternator?

thank you, the AA guys said the battery was fine and told me it was the alternator which is why I brought this up. If the alternator is dead ( because the voltage did not rise above 12 when the engine was started, will this have an effect on the new battery?

OF course!- it will not charge- you need to replace both now!
