Help Me With this Wiper Delay Circuit

[blown240]

After searching for a wiper delay for my Panel I came across this schematic. I like to tinker with electronics, so I am going to build one and see how it works. From what I read, this should give an adjustable wiper delay from 1 to 10 seconds.

Even better, I dug around in the garage and found most of the parts I need.

Here is where you electronically inclined guys can help. I need to figure out the smallest way to lay out the components on a circuit bread board.

Here is the schematic:



Built exactly like this will require a different wiper switch than stock, but it would be pretty easy to get the stock switch to turn on a relay to power this circuit...

I can't help you with your electronics project and while I am all about building things yourself, it is hard to beat these already made wiper delays.

Thanks for the reply Capitainfab. I didn't know there was already one available. If the one I build doesn't work, I may go that way.

Buy one. Pull the pot/switch off the board and extend it with wires to the dash mount the rest under.

I have two of the ones sold here on the board. One is installed and works great, the other is waiting on my lazy but to install it.

I have two also and they work great. You can get spoiled quick by them.

yup bought mine off the board a couple years ago

Installed mine a year ago. Really like it as well

[blown240]

Thanks got the replies guys!

I got mine build, but when it didn't work, I realized that one of the transistors I bought isn't what the guy said it was, so back to Frys. The thing I really like is how tiny the circuit is.

SUCCESS!! I got this working and it works very well!

Delay is adjustable from 1-1/2 seconds to 55 seconds. The pink wire goes to power, and the white wire goes to a relay to switch ground on the wiper motor.

[Captainfab]

That's good to hear that you got it to work.

When in delay mode, do the wiper arms always stop in the park position or do the just stop wherever?

[blown240]

Yes, the wipers park every time.

thanks!

I will try to get a video of them working later this week...

[blown240]

Here is a video of it working. It parks every time, and the delay if from basically none, to about 55 seconds...

This may only work with a single speed wiper, Im not sure. The cool thing is that there is still only 1 control for wipers...

[Captainfab]

Looks like it works good. Did you replace the original wiper switch with the delay pot?

[blown240]

Yup, Replaced original switch.

Thanks!!!

Its a real good feeling making something that worked out so great!

thats cool! you going to share the parts list?
