Wiper Parking

PostPost by: TYPE45 at aol.com » Wed Mar 24, 2004 12:43 pm

Simon,

I know this isn't the reply you are looking for, but in case you haven't done
this yet, the best way to improve your wiper performance is to install an
alternator. I noticed a dramatic improvement when I completed this conversion
last summer. Besides working faster, the wipers continue to work at idle! They
even work without the aid of lubrication (rain). How many Elan owners can
make that claim? Big improvement.

I've just had a look at my 68 Plus 2 and my 70 Plus 2S. The wipers on the 68 park on the left. The driver side wiper arm is cranked about 5 deg to the left so it lies flat at the bottom of the windscreen. On the 70 the wipers park on the right. Both the arms are cranked. Might be something to do with cheap job lots for the Lotus parts bin.

Imho, it makes sense to park on the left for visibility reasons, and it seems there is a choice.

You would also have to replace the wiper arms, as there is a slight
bend at the end so the blades will be parallel to the edge of the
windscreen when parked. If you simply parked them on the other side
the ends would be sticking up.

Try wiping the rubber blades with Armour All. It acts as a lubricant.

I replaced with Bosch rubber bits from halfords but these are

I need wipers that actually work, any suggestions.

And it will smear the glass when they're used in the rain. The
best -- both for smoothness and for effectiveness -- is to use
Rain-X on the windshield and then wipe the rubber blade with
the Rain-X'd towel. The windshield will shed water without
even using the wipers, and when you _do_ use 'em (like when you
get a misting spray from other vehicles) one swipe gives you a
perfectly clear windscreen.

I know this from using Rain-X on my other cars. 8^) The Lotus
both get the treatment, but aren't (voluntarily) driven in the
wet.

Best regards,
Bob

You want the wipers to park on the passenger side of the windshield. This allows them to clear an area closer to the windshield frame
on the driver's side. If they park on the driver's side there will be a large area in the upper corner of the drivers side not cleared.

Speaking of wiper arms and blades - does anyone know what blades will fit or do I have to get official Lotus parts?

Simon

If you reverse the polarity going to the motor it will certainly rotate in
the opposite direction, however since the rotary movement is converted to a
linear action via the eccentric and connecting rod, the end result will be
backwards and forwards instead of the original forwards and backwards.

Parking will still be in more or less the same place, but, the parking
switch and the motor thrust bearing is designed for one operating in the
original direction only.

Reversing the motor polarity wont do anything useful.

Long story, but I have my wiper motor out of my car and am reading the
service manual.

Section L, paragraph 28 (c)
Limit Switch Adjustment
The correct working of the limit switch is obtained when the setting pip
on top of the domed cover is in line with (in a position either nearest
to or furthest from) the central groove in the gearbox cover. Parking
of the blades in the opposite extreme position can be effected by
slackening the four gearbox coverscrews and rotating the limit switch
cover through 180 degrees before retightening the screws.

You can see the pip near the gearbox centerline in this picture. I
don't know if this position parks the wipes to the left or to the right.

BTW, anyone know how to get a wiper motor to work on the bench? My
freshly rebuilt wiper motor stopped working. Arrgh!

No - any blades fit - as I remember( havn't bought in years) 15 inch. I
personally like Trico. Usual disclaimers. George

Right - just what I have been saying - loosen screws, turn cover 180
degrees. George

Re your question, Jim - Watch out - my unit is NOT like in the manual -
it is an el cheapo - the switch has a rheostat that reduces field coil
voltage due to increased resistance. IF yours is like mine --- it only
has 2 wires from the wiper motor to the switch - armature ground and
field ground. Put power on the green wire into the motor, ground the 2
wires that go to the switch - will run at lowest speed and maximum
torque. reduce field (Yellow/Green) voltage, motor speeds up and
available torque drops. Ground the motor case too, so you can check the
limit switch. Need any more help - just ask. George

I must respectfully disagree... Unless I'm missing something here, I don't see how
altering the park position will alter the swept area. Parked left or right, when in
operation the cleared glass will remain the same...
