  6. Hello from Paula and her Vitesse

    When i put him in for an MOT a few weeks ago I asked the garage to change the oil and filter (i provided the filter).

    I do this just because it's a messy job and they have the ramp ot make it easier.
    I have developed a leak though. It's hard to say where exactly, but it could be the oil filter or the drain plug.
    It could also be a little leak from the head somewhere i've always had that's got worse.
    Looking at the drain plug where the oil drips from (see photo). Is that the correct plug? I'm wondering if it was lost and a modern one forced in.

    Opened fine on my Mac, but when you say 'that's the unit at its' fastest' isn't that just the intermittent? Next step is wipers fully on? I don't know exactly how the replacement unit works but surely the point of intermittent is to slow the wipers down and not have them on all the time, and you have the normal operation option for heavier rain? Unless I'm barking up the wrong wiper, so to speak?

    The problem is when the unit is on it can only give you intermittent wipers at various intervals. The video shows it at the shortest interval. To get the wipers to run constant you need a 3 position switch:

    Off.

    Intermittent: through the unit.

    On. Straight to earth.

    you also need a switch to turn off power on/off to the unit or it will constantly be clicking away. Bit of a faff really.

    Complete with a schematic diagram, which shows... that it wasn't designed for real world application. Oh dear.

    The "mode" switch appears to be of very little use and should, I think, be replaced with a wire link. It selects between operating the relay with a short pulse or a 50% duty. Because the wipers have self-parking, you only need to get them started, then let them park by themselves. At very short periods the two modes are equally OK, but at long periods the 50% mode will give you three wipes then a gap, three wipes then a gap. That's just silly. Oh, they call it "Cycling on-off". It's still silly.

    There is no "on-off" switch. At all. The design relies on the power being removed when you don't want intermittent wipers. But that requires the wipers to be top-side-switched (or at least, the "intermittent mode on" switch to be on the top side) whereas Vitesse wipers are ground-side switched. I suppose you could connect terminal 6 to +12V (the green "fused ignition" circuit, I think) and terminal 7 to the intermittent wiper switch (or first stage of a two-stage on). That would probably work as long as the circuit is isolated. And you'd need to wire the second stage of the switch to terminal 3 as I said above.

    Also, if your master switch is like the headlight one, the relay will keep clicking when you're on full wipers. Probably harmless but annoying. It might be possible to pull a fast one by moving the second stage from T3 to T4&5 (wire link between them, remember) with the result that, when both switch feeds are grounded, the circuit is powered and the oscillator is latched "on", so that the relay drives the wipers continuously, except that you would need to swap D1 and R3 for that to work. And depending on the value of R3, it might get warm.

    So, in short, I wouldn't have designed it that way.

    I tried to find the one in the club shop but it’s not there or hiding. What a faf.

    I’ll play with your suggestions and see if I can blow it up.

    I've been messing about with the wiper do dah. I've plugged it all up on the bench using a bulb instead of the wiper motor.

    With the knob turned all the way down the bulb comes on every 2 seconds or so, all the way up and it's every 40 seconds.
     

    I was expecting it to be constantly on when it was all the way down to give constant wiping.

    Have i missed something?

    Am i making sense?
