Thanks, yeah that's a thought, leave the existing switch as-is and
just use this to feed power to the 'low speed out' side of the
switch, using it's own switch. (I can't get near the wiper motor
proper, at least without major surgery. Best I can tell it's fitted
into the 'well' below the windscreen before the top part is welded
on.)

That's a shame, on some vehicles they're about the easiest part to
get to.


I know - not in this car though.

I have been considering splicing this
into the first stage of the switch then changing the second stage to
normal speed continuous and doing away with the 'fast' speed.
However if I do that I might need a diode on the output so it's not
back-fed during continuous use - if that's likely to bother it -
probably not as it'll be going into an open relay.

Exactly. An open relay won't be bothered by it at all. Just make
sure you wire the power connection on the relay to a constantly
active positive supply, not the power from the low speed motor
line. otherwise you might power the intermittent circuit even when in
continuous wipe mode (not that this will cause any problem except
unnecessary wear on the relay). Actually this will only be a problem
if the relay wired in the "normally closed" position, I don't have
time to check whether you'll need to wire it up like that or not
to get it to begin stroke as soon as the intermittent mode is turned
on.


I'll spend more time thinking on it when it arrives and I've had time to
play. Thanks for the advice, always appreciated.

Quote:
Actually the use of a diode (or two) might be handy if I can't get
the interval short enough to do a one wipe cycle. The voltage drop
might slow the motor enough ... (Thinking out loud.)

Not likely. A bunch of diodes in series might make enough of a
difference to the motor speed, but this will reduce the torque
of the motor as well, and generally be a rather poor way of
solving the problem.


Yeah, was a tangential thought while typing. Must learn to leave those out
.... Wink

Hi group.

My car doesn't have an intermittent wiper setting and I've been
trying to sort something out for a while now. I'm not competent
enough to make my own module with a 555 and perfboard and, unlike
back in the 1980s, fit-your-own aftermarket intermittent wiper
modules aren't readily available.

So I'm thinking that this might do the trick;
http://www.aliexpress.com/item/1-PC-12V-Cycle-Delay-Module-Cycle-Relay-Switch-Relay-Module-Timing-Chip-ControlCycle-Delay-Module/32348079007.html

Am I right? (I'm crap at deciphering Chinglish and going by
feedback there are no instructions with it.) I'm looking to wire
this into the first setting on the wiper switch and have it pulse
power say every ten seconds for two seconds or so then swap the
second wiper setting from fast to normal (I've only used fast once
in 10 years so, then only for 30 seconds I won't miss it.)

This is exactly what I want yeah? <fingers crossed

Put the switch of this device in parallel with the existing wiper
parking switch. and set the on time long enough to get the wiper
going and the off time to whatever, eg: 15 seconds.

Thanks, yeah that's a thought, leave the existing switch as-is and

on.)

It is highly unlikely that is in a welded in space, it would be able
to be removed,even if difficult, without cutting any body.


Yeah you're right. I just went out and checked. The linkgages and spindles
the wipers fix to are all inaccessable in the 'gully' but the motor is
mounted underneath with the drive spindle to the linkages going through the
firewall.

LOL! Speaking of Chinglish I found this today. It's from a description of an
audio amplifier on AliExpress;

"The 2.1 version of the amplifier design a single power supply, this is the
power of design, the main feature is cheap, practical, elegant design is
taking, light show design line, the machine can not find a jumper, clean
look hot moaning large pond filter NE5532 low frequency handling sealed
potentiometer Kingboard sided FR-4 1.6mm sheet from the perspective of each
element are perfect acoustics and aesthetics to consider whether or not the
intentions of the senior players at a glance!"

I didn't make that up, honestly! A friend wanted a small amp for driving PC
speakers so I was browsing the site;

Wow! My Chinglish certainly hasn't advanced anywhere near the
level required to decode that. I'm not sure if it's safe to
think about a "clean look hot moaning large pond filter". :)

Mind you, if you look up the forign Aliexpress sites I think
the listings are shown in their native language, so perhaps
it's actually an automatic translation by Aliexpress. Then
again they often reply to questions in the sort of tortured
English that I can't even imagine a computer being able to
invent, so I don't know. Maybe the sellers type in their
attempt at English and AliExpress translates that into
the other languages, in which case I can't imagine what
those poor forigners have to put up with.

Especially when you consider "whether or not the intentions of the senior
players at a glance". ;)

It's getting to the stage where I just look at the pictures on AliExpress
and maybe read reviews - a lot of which are translated from Russian.

(It doesn't help that I needed some large syringes ... I grow dwarf fruit
trees in containers and when it rains, especially when I've recently
re-potted trees, the water that overflows the saucers is full of the
nutrients that I carefully mixed into the media. So I suck it up and store
it in a barrel to be used in drier weather. The only syringes available that
are above 100mls are sold as sex toys and for 'rectal irrigation' so now my
search results and the 'you might also like' lists in confirmation emails
etc. are interspersed with some ... interesting items.)

Circuit board maker was discussing soldering and said to the chinese
