OK but which is the red light that comes on when you first start the car with a fully discharged lhm system? Discharge the system and check it out.
Maybe it's just me? But I'm not confident that we're fully communicating properly. I can't imagine how else that center light is coming on when you step on the brake unless it's a warning that one of your rear brake lamps is out?
Hi Bob, let us start from the beginning. I have this car for 10 years and I m absolutely familiar with the hydraulic system. The left lamp says stop and is the pressure warning light. This goes out after starting the car and I have the system tested the usual ways with headlights and brake applications. All checks out fine. The brake lamps are working.The pads are 70 % and there is no cable attached. Nothing has changed regarding the brake reaction nor feeling. The right lamp is for the handbrake and works. The center lamp never came on until two weeks ago, and then only on every application of the brake just for a moment. In the wiring diagram there is no indication of this lamp and there is nothing in the owners manual. On US cars this lamp is for the seat belt warning, as far as I know. Let us solve the miracle! Best, Rolf
Trace the wire back to what it's connected to is all I can suggest. Failing that call in Hercule Poirot and Hastings ... it is after all a French system and at least he's a Belgian ... Image Unavailable, Please Login Good luck.
I agree with Bob. Use an electronic wire tracer (available on ebay, Amazon, etc) and see where the wire goes. https://www.ebay.com/itm/PTE-Wire-Tracer-Circuit-Tester-Tone-Generator-and-Probe-Kit/202950623901?hash=item2f40ccc29d:g:TY4AAOSwngBegY9f Also, take a look at Table 23, items 119. The parts manual says it is for USA and Swiss delivered cars but your K being so late may have these brake components. I believe these are used to regulate the pressure between the front and rear brakes, and they have an electrical connector to indicate a failure. Ivan Image Unavailable, Please Login
Here’s an easy quick test, buckle both seatbelts, then see if the light comes on. If it does then that eliminates it being related to being a seat belt warning light like other cars.
According to Rolf the light only comes on when the brakes are applied and only for a moment. I can't see how seat belts would create this condition. Ivan
Ivan, I could be wrong, but I don’t believe anyone has come up with another Khamsin that has this warning light that isn’t for the seatbelts. Does the light come on while sitting still and tapping the brakes or only while moving? If only while moving, it could be something in the Quick deceleration is setting off the seatbelt warning, which is why I suggested buckling both seat belts as a quick simple test.
Here's the description for #119 from the parts book Italian - bilanciatori per spia circuito freni anteriori e posterori English - balancers for front and rear brake circuit warning light Sounds like those pieces are meant to balance against each other with differing springs in each unit and when one side over/under balances against the other a contact switch closes turning on the lamp. I suspect that the wire trace will connect with both of those on each terminal post.
Makes sense. IMO unlikely Rolf's is the only K with a unique custom config. My 1978 supports this hypo: Image Unavailable, Please Login PS Needless to say this abomination of a steering wheel is long gone---replaced by the proper Nardi.
So, seatbelt attached and tested and no change. Btw, the light only comes on on the first application of the brakes, if you pump the pedal several times, it does not come on again. Ivan, do you have a pic of the wiring and the location of the sender for the suspected pressure regulator? Thanx to everyone for their participation on the witch hunt. Best, Rolf
That could be typical ... were I you I'd try and find a LHM system specialist who may have experienced something like this. I don't know if this setup in the parts diagram is supposed to actually equalize the pressure and let you know one circuit isn't up to snuff or just let you know that it's not up to snuff? WO seeing the internals of those two pieces we can't know. So it might just be a way to let you know one of your brake accumulators is not up to snuff. I would be nice it there were a light for each one ... The Bora only gets one light to cover hydraulic fault and worn pads. Try calling Dave and see what he knows I don't know if this is Maserati only thing? Dave's a good guy. I've met him at the racetrack, he has modified early Biturbo track car. https://www.daveburnhamcitroen.com/ You might also try Gene O'gorman as he's owned one of these and he's active on this website.
Bob fyi Rolf is in Germany we have our own techs for these cars in the old world, he does not need to call people across the pond six and nine time zones away but it is wonderful to see the helping spirit here by everybody you included.
I would take help whereever I could find it. He is asking for help here ... I've sought help from all over the world for my cars. Gene is on the forum and has fixed, rebuilt and restored many Maseratis from 3500's through Khamsins.
The Nippon golden twins. One of the most alluring and intriguing K's in my unidentified cars folder has long been this gold black smooth nose beauty sold new in Japan. Note that even though they drive on the left in Japan all 31 Khamsins sold there were left hand drive as buyers wanted the car "just like in Italy". I emailed Fabio Collina a few days ago and, despite being on holiday in Rome he kindly investigated. It turns out that two gold K's were sold in Japan both Oro Longchamp, with black interior and five speed ZF gearbox. Both were also sent to the major market of Yokohama. Twins! One was AM120-0054 finished 26/4/74, the other AM120-0152, 23/9/74. Note the added zero compared to the normal pattern but we have seen this before. Then note that it was an intense year for production with aaa progression of exactly one hundred numbers (fifty cars as they only used even numbers for Euro left hand drive cars). Add to that right hand drive and US car production beginning that year and yes they were busy bees. Now the question is which car is in those photos I found years ago? I have to assume that because of the smooth nose in the first photo it is the early car: 0054. Of course there were exceptions, i.e. vented noses on early cars and smooth noses on later cars but most early cars were smooth noses. Also there is no way to tell which of the two cars is in the indoor show. But again probably the first car though with less evidence. Now the question is does anyone have photos of a Japanese gold K with vented nose? The quest continues! Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
