430 Mechanical Relays Replacement

If you read the F-Life thread you know what Stef suggests and what I did in response to his and others' posts. The relays are cheap. I replaced them all and carry spares in the car.

F-430 owner.
I'm looking for this PSR-7 relay with the part numbers.
46520411
232006

I would like to replace this relay on my vehicle however I can not find it for sale anywhere on the internet.

I was hoping somebody had a link as I tried to follow a couple other sources mentioned above and found nothing.

Really appreciate your assistance here.

I just changed out my F1 mechanical relay.
Just backtracking a little bit and found this thread with tons of great information.
Thinking it's probably best to change out this PSR-7 relay ASAP.

I do understand battery disconnect is part of the replacement any other tips or guidance would be appreciated as well.

I've searched all over the place I cannot find this relay.

Ugh...
Including scouring Amazon.

Thank you in advance.

I do have my car going in for service January 3rd I am getting an F1 transmission failure light but the car just had all its fluids changed so I'm thinking it's the actuator screws may have come loose.
But I'm also aware of these mechanical relays in the problems that they can cause later on especially on a 15-year-old car.
Car only has 11,500 miles on it but I can tell you this much that F1 pump relay look like it was baked in my oven.

Via some of the pictures on this thread I can't wait to go hunting some of these fan relays down to see what they look like as well eventually.

I would like to change out all the relays and I did follow a link to end up at a dead end .

 

What a great post I ran across this just recently as I still can't find a link for the PSR-7 relay.

Would you happen to have a direct link for that relay

 

It's been suggested on other forums that the PSR-7 relay is simply a 5 pin 30 amp relay with one of the prongs cut off. Some of these 4-prong relays do indeed look like they have had the middle pin cut off.

You might have to invest in a dremel tool.

 

Does thePSR-7 relay socket have a socket for the middle pin (with or without a metal contact)?

If it has a socket (hole), you may even be able to insert a 5 pin relay. Even if it has a metal contact, it's unlikely to be wired into anything.

By middle pin, I mean this one.

Not ideal, but a solution if you're having starting issues.

 

Thank you for posting this. I had not thought of this before and I like the idea of preventively replacing the relays.

Am I reading correctly that there would be a total of 13 relays across the 3 different ones you referenced?

 

Maybe I am blind but the contacts seem fine. Where is the mechanical failure or wear? Maybe the first one is an "Itallian weld" but throw some flux and reheat. Seems that level on pretty much everything.

 

Thank for the links. I plan to order a set. How many of each is recommended?

 

From my looking at this PSR7 is a 4 pin 30 amp ( no 5th pin cut off). Look up bosch 0-332-011-007 or fiat/ alfa 11129685. Should give S4P24592. If you look on the relay side the diagram should match your fitted relay.
The other switching relay 10/30 anp with 5 pins looks to be coming up as Bosch 0-332-201-107.
I am in process of ordering to try them to see if they do the job so research these numbers yourself to check if correct. These 2 relays will cover everything apart from the f1 pump.

 

Looking at the link it is odd they say it is 20 amp when the bosch info for this is 30 Amp

 

This is worth a look, lots of general Bosch relay info with the connection diagrams that match the 430 fitted relays

bosch-ibusiness.com

 

Has anyone already worked up a similar list for the 360? Many are probably the same.

The micro relays have been a problem since the 360 when Ferrari started using them. They are inexpensive from a lot of sources. Not bad even from Ferrari. I keep a bin box full of them. I have even seen bad relays on the horn causing it to be too quiet.

 

I have a client with a 360 that shuts down when driving, only to immediately restart after cycling the key. I've tried a lot of things with no success. I'm gonna try replacing the relays that feed the ECUs. Any other ideas would be helpful.

 

Might want to try the inertia switch down by the drivers left foot too. I have seen them with a little resistance on the contacts stop the car.

 

Bosch discontinued the 20amp relay...the Bosch 30amp is the direct substitute and with greater capacity, and should be more durable in use. Even when you find the 20amp listed somewhere, they will substitute and send you the 30amp, as they are no longer available and Bosch lists this as the interchangeable replacement.

 

That was the first thing I tried, a year ago. No luck.

 

I once swapped smg relay in m5 e60 dealer said it goes straight in
I asked them for location, they said it is the only one that color

Plugged it in and fried the wire harness
They sold me the wrong relay
Since then i dont bother

 

Just pull the 360 relay and see if it has the connection diagram on the side, then look at the link above. be aware some have a diode and others have a resistor across the coil terminals. 430 relays are resister type according to the symbols

 

Welcome to the fussy, quirky electronics of the modern automobile.

Several years ago I told my other half "Any car we will ever own has already been built".

 

Can someone please share the location of the N006 50A relays mentioned above (for cooling fans). I have purchased new ones and I have spent the last 20 minutes searching and am not finding where this is located.
