Regulator

    Hi Mike,

    I agree with Rob. We talk to lots of IRC mechanics and we aren't seeing a lot of regulator failures. A couple here and there, but after a while we see and hear about specific models that are having issues. When that happens it's time to take a look at the installation.

    The other thing to remember is posters tend to post problems, but all the others without problems don't post. Kind of the squeaky wheel thing.


    With 50K engines out there there is a failure rate just like anything else mechanical or electrical.     In this particular case Vans has a higher rate per capita failure rate. So the actual failures from what you read online may not be very representative. There must be a reason since other aircraft companies aren't having the same issue or Vans wouldn't have also set it up for relocation in the cockpit. This regulator is used all over the world and they aren't have wide spread issues. The regulator is better in an air flow area to help keep it cool. Too much amp draw or too little will cause extra internal heat. I read the Vans website all the time. With what Vans claims to have in operational RV12's in the field the failure rate is still low, but higher for a single model aircraft. Switching to other regulators that I have seen on the Vans site may cause issues down the line and not immediately. Poor wiring jobs can also lead to early failures.

    The Polaris side by side off road quads are having the same issue. Most of the failure guys have what I believe as too much amp draw and their side by sides are loaded with electrical equipment. The regulator is also mounted an a poor airflow area. many have moved them into cooler operating areas and are not having any issues. The guys with a ton of electronics may or may not continue to have issues.

    I moved my regulator on my Polaris Razor 1000 from the low rear mount to up front under the hood area and it stays nice and cool.

    We've had our aircraft for 3 years and have gone through 3 Regulators. Not uncommon.

    As long as we're conducting an informal survey: Replaced 2 regulators over the last 2 years in my Remos G-3/600. Remos has addded the Schicke regulator to the G-3's TCDS.

    I had a problem with my Evektor EV97 ( sportstar ) regulator.

    The problem was coming from the poor terminals on the connector,( particularly the two « G » terminals)

    I removed the connector and installed a separate terminals ( inox ) on the new regulator

    I strap all terminals to avoid vibrations

    I also added a mass port between the case and the fire wall because I had noticed oxydation at the rear of regulator and poor contact for negative terminal

    It’s now easy to visually check the good connection between the regulator’s case and the fire wall ( connect at the negative terminal of the battery )

    Since then, no problem ( 6 Years ! )

    Installations can cause failures and then someone may want to say it was the reg's fault. Then they install another one and it fails (like some on Vans), but if you have this kind of an issue it's time to look at everything else besides the reg. Anyone can have an real failure of a part, but when they are grouped together then it's time to look else where. MFG's can and do make mistakes as we have all seen if you have a few years on you. :lol:
