What have you done to your Maserati today?

Mice.
Whooshed along to my trusted motorfactor to have the a/c recharged.
An hour and a half later the chap was puzzled. Blowing ambient air.
When he'd removed the nearside engine cover/access panel, he'd observed what could be construed as mice attack, wires.
Might explain an intermittent nearside sidelight error.
Awaiting torx t45 driver tomorrow.
Autel 200 diagnostics indicates B1973. Compressor error which combined with blowing hot air, might indicate too much refrigerant.
We'll see tomorrow.
Anyone good at fixing mice. Better still anyone versed in ac compressor wiring and whether it's routed on the nearside?
 
Well on Tuesday I gave it a run around the Mach Loop in Welsh Wales, stopped off at Corris Craft Centre for a brew. I noticed a few plane spotters on the hills waiting for low flying stuff, all they saw was a blue blue with a V8 as I dashed to Oswestry and on to home.
I can safely say that it's in fine fettle and coped with the 30⁰+ heat in traffic, the air conditioning is super cool and it's ready for Le Mans. So today, it got a wash, and it's ready for a NW Italian meeting on Sunday. New boots the following Sunday and then off to Poole to meet the gang.

It seems that discovering the correct capacity for the refrigerant is inordinately difficult, usual sites don't quote. Google picked up from some unknown source that it is 1,100g, which is what the engineer filled to.
On returning yesterday that were more than happy to experiment, in the knowledge that the B1973 code has more than one cause, only one of which is over charge of refrigerant, and we were worried about the wiring down that side.
DIscharged to 600g, compressor clutch kicked in, and a/c working. Error code disappeared.

A useful bit of advice if you encounter this:
1. 1,100g may cause this
2. whether as low as 600g is necessary is doubtful, but some degree less than 1,100g
3. I've had a 'chat' with google, informing them that 1,100g is incorrect.
4. Dear old google immediately trusted what I said with no verification, and resounding reinforcement of the finding.
5. Google AI : "garbage in, garbage out"
Below is the screen shot of the advice and update after my response.

Also, the frayed wiring is still worrying and maybe the cause of the sidelight failure

Completely useless

Well not *completely* But in this instance, unhelpful.

If you know what you're doing, AI can be useful. For example I can't write code for ****, but I *can* define an input state and a desired solution. Now instead of begging for help, I just 'talk' to Claude.AI and it writes my code for me. This year I've managed to completely sort the heating system at home. We live in pretty big house but during most of the day, there's only me and the cats. We *did* have TRV's all over, but they've been swapped for ones that integrate in my home automation and now we have night / away and day preset temps for each room, plus some other ones that trigger when someone is *in* the room. Should save some money, but *nothing* to do with Maseratis :)

Most search engines are now quite useless if the subject is precise and relatively niche, being slewed toward commercial and don't sift out the irrelevant.
I've used Google a handful of times, and found that it is exceptional in discovering the precise narrow technical issue.
I've verified them, recognising from where the data has been derived, and thence the response is couched in 'natural' language to appear modestly human and credible.
But that's all it does, assemble from vast sources, and we should be grateful that such massively parallel processing resource and data is searchable and refined succinctly. For free. I don't have to subscribe to the learned science journals to have access.
My interests are very niche, manly concerned with either flight control, navigation or niche physics. The sources are limited, so I can usually recognise from whence they come.
The bulk of the response each time is correct, I recognise the source, but the response always contains at least one item of completely wrong information which it's picked up from either out of date information or provided by opinionated layperson.

It's an excellent search engine. But no more. Always verify.

A week before my road trip to Le Mans the rear passenger side window regulator has failed allowing the window to drop, bugger.

A temporary solution which will get sorted properly once back from France :-)

Hopefully that’s not going anywhere !
