      Six weeks dry now and no looking back. How the world looks now is a funny place. I`m not liking it through non clouded eyes. But hey ho. I will just have to live with it. From a bottle a day to nothing was easy as eating a meat pie.

      So whilst driving around in MK6 I hear a sloshing sound. After making sure I didn't need the loo I discovered my drivers door full of water with the little drainers blocked. A surprising amount of water came out!

    • all my experiance says anything over 14,5 volts is bad, i have never seen the flattest of batterys make an alternator go more than 14,5 volts,  i would say if its a alternator is faulty
    • This is actually about an alternator/regulator for my Fiat Sedici, not specifically a Hilux question, sorry about that, but it is of general technical interest regarding alternators. I bought a replacement alternator but I am sending it back as I measured and have seen it running over 16.5V. The manual says the regulator should keep it to a max of about 14.5V. I put a brand new and fully charged battery in at the same time the alternator was changed, so I don't think the battery can be blamed. Also at the time I tested it, was running as little electrical load as possible, no lights, fan off, radio off, etc. The seller has accepted a return on the alternator, but also sent me this advice: "if you fitted this alternator to a vehicle with a flat or faulty battery it will perform eratically . most alternators are engineered to charge up to 18volts for short periods of time to replenish low battery voltage or cope with high electrical loads" I am not sure I believe this, is it true? I only really have my trusty Mk3 for comparison, and that has a simple voltage regulator based around a zener diode type setup and that is designed to cap the voltage at 14.5V, nothing more fancy. Do more modern designs really have this kind of 18V boost feature? I think the alternator is shooting up over 16V, and this is causing the ECUs to protect themselves and reset - dashboard lights all go off and the power steering stops working. Its an intermittent fault, at first I thought a loose wire. Was a cheapo chinese job of fleabay, I should have known better...  
    • Did 80 miles over the Sat/Sun in our town driving around stop start, loading and offloading bit and pieces to the new house. 28 MPG. Did a long run out on the previous Sunday with a return on the Friday, total 470 miles, mostly motorway @ 60/70mph, managed 32 MPG. Rolling Cooper S/T Maxx, 225/75/16, so not exactly speed wheels. I'm happy  Only use BP or Shell diesel now. 
    • Awesome, thank-you. A rep point your way. This is exactly the information that I needed (and you seemed to know what my follow up questions were going to be too!) Brill, thank-you too. Only allowed to give 1 rep point a day at the moment (until payday when I can become a site supporter I figure).
