    Same here, though I'm virtually CERTAIN that my issue is old grease. Yesterday I took the 308 out for a drive in 95 degree weather, and the windows were quite quick and smooth. In winter, they become slow as molasses.

    EDIT: Actually, it *IS* more than just the grease. It's a power issue too... I noticed today how much slower the windows move when I'm doing both at one time, in contrast to just activating one.

    Hi All and Thanks Samy for the wiring diagram! any way, now that you can all make them, I hope you remember who thought of it. I am hoping I can sell some more as I got enough stuff to make 40 of the things lol. I am hoping there will be people who cant be bothered to make them and still come to me. Hopefully there will be some reports soon because I have sent out to 6 people so we should here back on how it went. about the comments on my module only half fixing the problem by only fixing the earth side of the circuit and not the 12+ side of it. remember a couple of things, this is a simple fix that can be done with out having to go to the lengths of changing the cars wiring and also remember the rule that current is common within a circuit, so by doing one side of the problem increases the current flow in the other. + if the window now fully satisfies the owner, should they need to go any further and upgrade the wiring on the 12v+ side? All things aside, I am glad to of helped, and I have really loved reading all the comments, I am new to forums and it been so exciting!

    As I mentioned in my email, I will absolutely buy several of them once I test it out. Don't worry about losing the market as people try to make their own. Some will, some won't. Many people will place a value on their time and determine it's simply easier to buy one off the shelf and install it in a few minutes.

    Hey, at the USD$30 per door price you've got on FerrariAds, that's a DEAL compared to the trouble of making your own, and I'm definitely going to recommend this solution to anyone who complains about their windows.

    Don't you worry about that pall.

    As for you selling the units. So long as to don't try to sell them at Ferrari prices I don't see you having a problem. They work and they are priced right. Don't get greedy.

    I dont know how the 348 is wired, or later 308/328 either for that matter. What I do know is that both my 77 308 have the ground wire from the door switch attached to a stud inside the door. When the car was new, with clean door pins and clean hinges, it probably could find an okay ground. 30 years later it may not ground so well. It would be a bit tough to slip one more wire through the door, especially with the door on the car, but it definetly needs a better ground.

    I think it is a great solution and you will most likely have to make about 50-100 per year to satisfy demand. A good price will make it almost pointless for anyone to build one themselves. I know I would rather just buy it and install it. Oh, and thanks for taking the time and thought for such a nice solution to a very common problem!

    Ditto! For the price point not worth the aggravation to break a sweat fabricating one, especially when bric's look so slick.

    It is a good price, but it's not $30 (it's £'s, not $)........

    "Introductory price for June only is GBP £30 per kit, from 1 July onwards price is GBP £39 each."

    Two relays must work....It doesn't matter if the window is going up or down... it always has a solid ground. I bought the relays and the diodes for € 7,-

    If the current goes from .... + to - .... RL 1 is activated and will give a ground where it is needed. If the current is .... - to + ..... RL 2 is activated and will give the ground. :)


    I am going to do this next week and ceep you update.

    That's from his website. If you look at the link from his FerrariAds.com post, it's $30, a very reasonable pricej and about what you'd expect to pay.

    I don't have a problem with the price, but the shipping delay is another matter. Have any 348 Brothers received these units yet?

    I'm in the UK and got mine in 2 days flat. Excellent service. I might try and fit them tomorrow but it's a bit more difficult in my GTC thanks to the carbon/kevlar doors.

    €7 = $8.75 which means your time is worth less than $20ish - how can you afford a Ferrari?! :D

    UPDATE: I received mine yesterday 6/24. Took about a week to get them. They took only about an hour to put both units in. Just followed the pictures on the website for installation. It was very easy and the windows go up much faster. I really think there worth it for the money and ease of installation. I was going to post pics, but it would have just looked like the website pictures. Thanks Frazer nice job! PS I like the little note inside the sealed box.... yes, I had to look inside.

    Just to follow up with Brent's update. I received both my units today. I spent around 30mins fitting the drivers side 1st.(RHD) I will do the passenger side tomorrow. I did a before and after test(RH) before i fitted it...It took 5 seconds to go down & 6 seconds to go up(engine off) After fitting the unit... it took just over 3 seconds to go down & just over 4 seconds to go up(engine off) That's around 2 seconds quicker now. :) With the engine running, with them fitted, its still around 4 seconds to go up. I even tried what Frazer did in his video's, touching the earth wire to the door to see if it really was any quicker. It was not as spectacular as Frazers video. :p It did nothing. My RH side was never really a problem. The slow window is the LH side. That takes around 15 seconds to go down and around 25 seconds to go up(Ill time it properly tomorrow). Here are a few pics, although it really is as simple as looking at the pics he has on his site. I shortened the window motor wires around 6 inches and the earth wire 2 inches. I used an industrial strength double-sided tape to hold it in the bottom of the door. It aint going no-where. I was going to solder the 2 window motor wire connections, but never worried about it. Very very to install. I will let ya's know tomorrow how the slow LH side goes. Cheers Frazer!!

    Hi, I see that you keep referring to the low cost of the parts in your diagram. To me, it sounds like you are pointing out how expensive my module is. This Whole thing wouldn't of happened if I didn't think it up, a percentage of this is in my price. Its easy to work a diagram out once somebody shows or tell you what it is that you are designing it for. what I am saying is I am glad you have managed to make your own, but please stop missing the issue that I invented it, and its not all about how much cheaper you can make one for. I offer an immediate shipping service, quality boxed product, fitting instructions, full support and help on fitting. Also I have tested my modules to death and I have produced a test bed for every one to be load tested before they are shipped. all this takes me time and money. Each one is hand made and takes about 1 hour. There is the cost of the materials which is far more than you are quoting. TAX and Paypal Fees all need to be taken into consideration. On a different note, I am expecting some owners to report back soon with how they get on. I have had some suggestions on how they could be wired in with out cutting the original wiring. see below.

    -------------------------------

    "rather than cutting off the Ferrari connectors, just slice off a little
    of the wire insulation on the chassis side (the red and yellow wires?)
    without cutting the wire itself, then double over the bare wire and
    stuff it into the crimp connector.

    That'll leave the spade connectors so you can remove the motor without
    cutting wires.

    Hope that makes sense.

    Even better, if there is enough room in those plastic covers, you could
    use one of those
    piggyback connectors that let you attach an extra wire to a connection.

    Crimp the piggyback onto the ends of your wires, and all you have to do
    is separate the Ferrari
    connector and plug the ends into the piggyback connector.

    I believe they make the piggybacks uninsulated too (or you could cut off
    the plastic), so
    it's possible the piggyback could get folded up enough to jamb back into
    the Ferrari plastic cover.
    If not, you could either supply new bigger covers (admittedly, I don't
    know where to get them) or
    a chunk of heat shrink tube and a couple zip ties would work...or tape."

    -----------------------------------------

    Again thanks for all your comment and support, im off the post office now..... it raining here in England, best I keep my red car inside today...LOL

    Jack,
    Don't worry about the other guy making some units for himself. I think any response you give makes for more arguing. At $55 they are a bargain, and I think 90%-98% of us understand you want a little money for thinking this thing up, and getting them produced and will be happily paying it. I personally see myself getting a pair when the weather gets a little cooler in florida, for now it is windows up all the time!

    Come on…is it not that we are trying to find out how things work here all the time ??.

    The idea was not mine and I don’t claim it…. ….

    I don’t sell the units and I am not going to. I just wanted to point out what’s in the black box and how it works.!
    Don’t shoot me for that………

    I thought the meaning of “ferrarichat” is sharing knowledge and idea’s …and not benefiting our self by keeping a simple solution in a black box.

    You have never bin here before ...It started with selling you idea..

    Sorry its just my opinion…

    I get what you are saying and it is true. But the reality is that to make something worth buying, you have to get a run of them manufactured and that costs dollars. So I think it is fair to repay the thinking person that takes the initiative and keep it worthwhile for them so others might do the same thing if they have an idea. Now, if Jack was charging something outrageous (like $300 per door) I would think he was solely in it for the money. I think the price of the unit is fair and we should support those that solve common problems like this particular item has the potential for. To me he just is looking to be fairly compensated for doing the thinging and getting the item made.
