Re: Idle too high

lol don't blame me, I'm also coming to terms with the reality of living in America, writing on a UK forum, about an Italian car

Will report back when I hopefully manage to unscrew the hoses.

Edit: I wrote in another thread asking about popular websites to order from, but no one replied. At the end of the day pricing is pretty even across the board, it comes down to shipping. Anyone have any recommendations of a website with fair shipping costs to the US from Europe?

Re: Idle too high

The two I use the most are, but I am in the UK, they are reasonable for shipping to here and very helpful.

https://www.fiat500vdlaan.nl/en/index.php.

Leo is the main man there, so could be worth an email to him for shipping costs.


https://webshop.fiat500126.com/?&&gc...FdUaGwodqP0ItQ

I can't remember the name of the guy I deal with there? But very helpful. Both speak good English.

I normally add everything to the basket then cut and paste the basket in an email to get shipping costs, then pay with PayPal.

UK based spares companies are a rip off, you pay at least a third more for the same thing you can buy in Europe even after shipping costs. The UK ones sometimes charge more for shipping than the European ones!

I am sure some of the US based owners will chip in with their experiences.

Re: Idle too high

You could always check passione500.it
The shipping estimates at checkout are usually wrong and if you email them with a pic of your cart they can provide an accurate one. Mine was a good $60 cheaper than the estimate at checkout.

Re: Idle too high

My contact at "Axel Gerstl" (www.fiat500126.de) is Frederik Stollenwerk--I always get good service from him, and prompt response to my enquiries. Going by the communications that I have had back from him, he would seem to speak excellent English. The main supplier for classic Fiat 500 parts in America would seem to be "MrFiat", in (I believe) Atlanta. The main advantage of building up a relationship with your 'local' supplier is that if you have a problem, you can talk it through with them in your own language!

Re: Idle too high

Thanks guys. I was already making a list of stuff on fiat500126.de , and they have been helpful so far via email. Shipping seems to be the most reasonable compared to the others.

So now for my next query

I noticed that on my dashboard, the only lights that work, are my Gen. light and headlight light.

1.The indicator light (on the left of speedo) doesn't work.
2. The high beam light (on the right of speedo) doesn't work.
3. Fuel light and Oil light don't work
( 4. License plate light doesn't work )

I've troubleshot the bulb and bulb housing with a multimeter, and they seem ok. So now I need to figure out why they aren't working. Any tips on how to troubleshoot the wiring and connections?

My light switches work, high beams, position lights, indicators etc.

My first point to check with any electrical problems on my Fiats, after checking the fuses of course, is to make sure every earth point is making good contact so that is where I would suggest starting

Re: Idle too high

Fuses are all untouched, but they are also not the standard 8a, but 16a and one is 25a...

So, I went through the electrical diagram, and cleaned out each connector, tried inverting cables, etc but the only thing I managed to solve is the high beam light (blue). It now turns on when high beams are on.

The indicator light on the left of the dash still doesn't work, and it's not a housing issue, because I inverted the high beam and indicator lights to see, and it's definitely a signal issue.

I used a multimeter to go through each cable/switch/lightbulb, and they all gave back a signal (using the ohm open circuit setting).

I'm trying to figure out which earth points to go through, and considering that the light switch + headlights/position lights/indicators work, I don't get how, for example the rear license plate light, doesn't work, when it's in the same circuit as the tail lights (and those work)


Here is the mess that is the fuse box, don't worry, rubber grommets are on the way:


Main lights switch:


Wiper switch and key:


Dashboard lights switch + high beam blue light:


After cleaning the switches, and light bulb connectors etc, the only thing I've succeeded in was to get the high beam (blue) light to work. I'm also facing the issue of the green light on the dash being inverted (so being on when the lights are off, and it goes off when I turn on the lights ). I've inverted the switch leads but it doesn't change....

Re: Idle too high

I had a lot of similar problems (I have a new loom to fit but not got round to it)
I found that the terminals being corroded did not provide the best connections, and crimping them up did not do much good, only served to make the contact area smaller...
they need careful cleaning not roughing up with sandpaper....
even though using my meter to check for continuity proved there was a circuit, a check measuring the resistance showed a high resistance over some of these connections...

I have seen on many classics the loom is left in place.....
on a 500 they are very cheap... and they are not complicated circuit wise...
If it ain't broke don't fix it but if it's worn out it will cause problems, and old looms are mostly worn out...
you would probably be ok with good electrical contact cleaner and going through everything....
this will even include the bulbs (correct name lamps-bulbs are what you grow flowers from), switches (inside contacts!!!) and the fittings... anything that could be part of the circuit...
One duff connection can cause current to flow differently.. how many times have you followed a car and seen withe the stop/tail lights flashing with the indicators or the indicators coming on with the stop lights.. the car has not been rewired.. simply a bad earth somewhere, so the electricity finds a different path...

just my opinion...

Re: Idle too high

Thanks, out of curiosity what settings and values should I be looking for with a multimeter?

I went through all the bulbs, and most of the cables, and they are showing a complete circuit, but I think I need to check the resistance.

Re: Idle too high

What model 500 do you have? If it is a 500D, according to my 'Factory' book-of-words, all fuses should be 8 amps. Also, the photo you have shown does not match the wiring diagram you have shown. According to the photo, the 2nd wire down on the right of the fuse box (and it should have an internal connection to the top terminal) should be green (verde), and go to the 'Outer lighting switch'--there is no wire to the top right terminal. Lastly, the bottom right wires should be red (rosso)--1 goes to the positive side of the battery, the other wire goes to terminal 30 on your ignition switch (lock switch in 'Fiat-talk'). The wiring diagram you have shown does not have this battery/fuse-box feed and diagram is possibly for the 500R. I am NOT an electrician, but having just had to sort out the wiring on my 500 after it came back from the body-shop (with, let me add, a great deal of assistance from my son who is far more 'electrical' than I am) I have suffered similar problems!

Re: Idle too high

hard to say what a high reading is...
but if you measure a simple piece of wire....
then anything above that will be high...
but it is more a case of noting that you get no or erratic continuity either side of a component or connector... worse when the connector is wiggled...
I have a set of leads with crocodile clips on so I can attache the meter and wiggle stuff... when set to the audio "buzzz" it should remain constant..

As Tom has said what car?.. it's not and N or D because the speedo is held in with Push clips... on the speedo body...You need an accurate Diagram for the car.

it does seem to have a bit of a mix of switches etc.. round and spade terminals....
Time for a tidy up I think...
It could actually be something in the Steering column controls shorting out....

Really hard to fathom, but sort the fuse box out and make sure you have power to the other side of the fuses......

If you are not sure then get someone to help.. or things can melt..

Re: Idle too high

Fuses definitely 8 amps throughout. Use the diode symbol setting on multimeter for identifying earth connections and checking fuses.notek Use the 0.00 v dc setting for finding a 12v feed. Check that voltage appears both sides of fuse. The fuse box type shown are famous for having loose fuses / voltage problems.

Re: Idle too high

personally $38 + $9 shipping.. (Mr Fiat as you are in the US)
I'd simply put a new fuse box in to start...
and new fuses..
clean up the connectors and label them...
nothing fancy just 1-6 each side with a bit of masking tape..

Yep I have 8a fuses coming in this week. It's a 500F as some of you have correctly spotted. I might end up getting a whole new fuse box and maybe even a new wiring loom

When you mention to use the diode mode, is this always with the battery disconnected yes?

I've done a continuity test on almost every cable/bulb/fuse and they always come back buzzing. So unless I'm doing something wrong on the multimeter, or the cables are in the wrong places, I don't get whats going on.
