    I've talked to Daniel and ordered a connector/pin kit. I'll do some comparisons of Domestic/Japanese connectors, hopefully with pictures, and maybe we can find a sulution. I'll then pass the info on to Daniel who will see about trying to stock the pieces as an upgrade kit.

    More in a week or so

    I recently experienced sarting problems on my 83 Mondial QV. The starter would crank but the voltage at the twin Marelli Electronic Ignition Amplifiers was insufficient to make a spark. The cause turned out to be a chronically weak battery caused by inadequate charging voltage from the stock Bosch 80A Alternator. The problem always disappeared after I charged up the battery overnight. It also went away after a long highway drive.

    So I measured the charging voltage through the cigarette lighter socket during driving and found that it was always below the desired range, which should be 13.8 to 14.2 volts. It was only around 13.3 volts and maybe a little higher when the battery was just fully charged overnight. I checked the cut-off switch, the connections at the Alternator, and some but not all of the under-chassis electrical connections. Voltage drops amounted to maybe a few tenths of a volt. I suspect that the problem is with the Integrated Regulator & Brush Module located on the back of the Alternator. It just might be worn brushes. If not, I have heard that there are drop-in replacements for this Regulator Module that will deliver 14 volts as it should be. It may be possible to replace this Module without removing the Alternator if the car is placed on a lift. Has anyone tried this?

    By the way, Daniel, great "presentation" in your photos. It's nice to see someone take pride in the way even car parts are presented........I think it reflects an effort to be a step above the others

    Do you have the male side that goes on the circuit board?

    WOW. that looks like my pin connector but mines burned out at the a/c fan pin. Daniel, you never answered me if you had this connector but I guess you do. Can you PM me the specifics please?

    I'm glad I found this forum. You see I've found a really really cheap 1985 Mondial from an old man that just wanted to get rid of it, due to sentimental reasons, the car brings him memories that he would rather forget. Of course I have not hesitated one second and bought the car right away, after all, I have never had a Ferrari and as all, have been dreaming about it since I was around 6 Years old.
    The problem is, and I knew this all along, the car won't start. The starter motor won't even turn, replacing the battery, which would be the obvious problem, does not solve in any way the malfunction.
    Do you think I need a new starter motor or may it be somekind of connection/solinoid problem?
    I understand that, in spite of the famous electrical problems, like the fuel pump fuse and others, this is one of the most reliable Ferraris one could get. Is this accurate?
    Many thanks :)

    When they are fettled, the Mondial is one of the most reliable and usable classic Ferraris, although with the some time electrical gremlins.
    As to your starter problem, and assuming the engine can turn:

    Would check and clean the ground at the battery
    Check voltage and clean connections at starter (a possible weak point is the long wire that goes from the starter switch to the battery).
    If the voltage is good at the starter and still no start, then would swap/rebuild the starter solenoid (after trying hitting it with a spanner to loosen it up first if it is gummed up inside).

    As usual, if the cam belts have not been changed in a couple of years or it is uncertain, would do this right away as the priority. Broken cam belts will trash the engine.

    Check this thread, especially post 19:

    Good luck and have fun!

    Upgrading Mondial Alternators!!!

    While not one to usually reference off-board thread, there is a great discussion and 'How-to' in the technical section on the -Talk website on upgrading Mondial alternators to a 120 Amp Delco alternator as well as the advantages of going to a 3 wire system over the current one wire system.

    While we are all still patiently waiting for the fusebox solution, I really think this 3-wire thing makes a lot of sense for our cars, is easy, relatively inexpensive, and has a lot of promise.

    I need to ground my Electromotive Xdi on the engine. Where is the best point??. I was thinking on a cam cover bolt. Or can it be fitted anywhere on the engine. Thanks

    I need one of these badly! Did anyone come up with stronger connectors though?

    The reliability world insists on gold plating.

    Unless the connectors come GOLD PLATED their life is limited to 3-5 years or less.

    What oil can I use on my Ferrari Mondial 8 3L (I bought 5W 40 Diesel syntetic) but I'm not sure if it's going to give any issues what other brands and blends can I use it if the one I have doesn't work, also the air filter any after market brands (stores around me are Canadian Tire, parts souce, piston ring, Napa) thanks in advance for any kind of help

    Hi Everyone, I am new to this as having just purchased a 1987 3.2 Mondial, UK spec. I have discovered that the daylight flashers do not work. The handbook says they are the long lense below the indicator but they are actually the front fog lights which the handbook says are optional. Question is if i have the optional fog lights where the daylight flashers should be then where are the daylight flashers? When ignition is on and all lights are on i pull the stalk back but nothing happens at all, no matter what position the stalk is in.
    Secondly, the dreaded glove box will not open. Fuse is fine, relay must be fine as it shares other functions that are working ok. Is it a solenoid, something easy?

    All responses are greatly appreciated.

    Peter

    Welcome to FerrariChat and congratulations on purchasing your Mondial.

    Sorry that I can't answer about your fog lights as I've never seen a UK car or it's owners manual.

    However, regarding the glovebox you may find a solution here:

    I am very surprised to hear that the fog lights were an option. To make a long story as short as possible, I imported a Mondial T from the US into Switzerland and had trouble with the importation because of a broken fog light glass. Need less to say the fog lights are as scarce as hens teeth and I asked the importation inspectors if I could just eliminate the fog lights and they said that Ferrari told them that they were NOT an option. More incongruous (read crazy) info concerning our cars! Good luck and welcome to Ferrarichat. It is priceless.

    I know this post is at least 2 years old, but I gotta voice my thoughts on this. It's not an issue of what metal the connectors are plated with, it's whether BOTH connectors are plated with the same metal. Dissimilar metals will have a high rate of corrosion when they make contact with each other due to their galvanic properties (aka galvanic corrosion). IF the metals must be dissimilar, their anodic differences shouldn't exceed 0.25V on the Anodic Index. Gold is nice for its conductivity, but if you have one gold connector and one that's not gold, you will experience a very short lifespan of reliable connectivity.

    Sorry for the blurb; I work in a technical field, and this is my 2 cents on the subject. Google "galvanic corrosion" for more info.

    Welcome Peter, this really should be a new thread but to answer your question on the daylight/fog light, its illustration A. To activate the daylight flasher, just press/pull the light lever towards you. At least that's how my 88 works.
