INTERMITENT WIPERS?

[dirtworksequip]

Is there anyway to incorperate some kind of delay or reostat into a standard one speed wiper to make it an intermitent wiper?

I've seen aftermarket add-ons for cars, don't see why you couldn't do it for your tractor.

Bingo.

Thanks Will, I see your lurkeritis has advanced to lurkeritis-uwritus.

lurkeritis-uwritus.

Ya, lately I've had quite a bit of free time on my hands.
Been nursing a fractured rib. 6 down and another 2 weeks to go.

Get well soon! Thanks for the help.

Hope you're better soon.JC Whitney has one I've used for several years(much cheaper)

1*Wire one of those switches that controls the brightness of your dash lites into the wipers.
or 2* wire in a turn signal flasher.

You can make one for about ten bucks with a TTL 555 timer chip, some resistors, capictors, potentiometer, relay and a switch.

Here's a link to a kit for under $15.00.

Moss, good idea. I don't have enough knowlege of elec. to put something like that together. Thanks for the thought.

Mossroad has the right idea.. a rheostat would be a super poor choice to slow wipers.

A timer triggered module ( can be built with a compariter and a slow charge cap circuit.. Can also be built with a mosfet, setup as a PWM. Way better motor controllers because you have full supply voltage and current.. just on time is sliced up.. vs a rheostat that drops voltage and reduces current.

I've used them to control wipers and heater fans.

I built several of these 20 years ago, back before most cars came standard with wiper delays. GM cars just put 12V onto the wiper relay to turn on their wipers. All this thing does is let the 12V out to the wiper relay at intervals that are adjusted by the potentiometer. Mine were adjustable from 1 to 20 seconds. I also had a switch and circuitry to make the wiper swipe twice, then wait. You know how sometimes one swipe almost gets it, but just quite not enough...

A PWM is a -way- better motor control than a resistive element, as it still allows the motor to draw the same current.. and thus have less chance for stall at slow speeds on the brush type dc motors.

For ac stuff.. triac based controllers are good and easy to rig.
