Ok Wiper motor.

three wires

 

earth sorted.

 

2 lives 

 

1 live will power the wiper but will not start the motion

 

2 live will start the motion. (and keep the motion going even if 1 is disconnected)

 

so if i have 1 connected nothing happens until i trigger it with say a Mom. switch on 2. it will then stop until triggered again

 

then if i have 2 connected the wiper will run until switched off but it will stop at the switch off point no home return which is there with 1 connected.

 

how would you wire this up

 

i can do the single wipe and self park with a OFF/ON/ON+MOM  but the continuous with self park has me stumped.

 

i am thinking it will be two switches.

Right, last time I did this it made my brain hurt as I seem to remember I bought a triumph spitfire switch to get
an xjs wiper motor working on a Kitcar as I couldn't figure it out. I'm pretty good with wiring but that had me pulling my beard out

Here's a thread on retro rides, any help?

yes kinda. changed my thinking the 1 conection should be live 24/7 as it is actually off (could be switched as an override).  then if i use a on/off/mom that should work fine .

Hmm so your saying there is two lives 

 

Live 1 (park switch contact Live )  - will power the wiper but will not start the motion

 

Live 2 (Run Live ) - Triggers the motor to start  (and keep the motion going even if 1 is disconnected)

 

 

 

If Live 2 is powered but Live 1 is dead ,  the motor runs continuous 

If Live 2 is powered but Live 1 is dead and Live 2 is disconnected the motor stops instant no park

 

If Live 2 and Live 1 is Powered , motor runs continuously 

 

If you keep both live then disconect Live 2 the motor parks and stops? 

 

If you Make both live then disconect Live 1 the motor keeps going

 

As for if both are dissconect the motor should stop instant 

 

 

Is this all right?

You could use a single 2 position 2 way (ON/ON) switch here. Wire your 2 positive feeds to the 2 outputs from the switch. That way when switch is in position 1, live 1 only is energised so self park function operative (effectively your OFF postion). When switch is in position 2 the live 2 is energised so starting the wiper. Not clear if you need live 1 to be energised for live 2 to be able to start wiper. If you do the just wire a diode across live 1 and live 2 such that current can only flow from live 2 to live 1. That way when switch is in position 2 (effectively your ON postion), live 1 and 2 are energised so starting the wiper. Turn the switch to position 1 (OFF) and live 1 only is energised so wiper continues until parked.

no it does not if 2 is powered up only the wiper works and stops where you switch it off it is also needed to override the auto stop in the self park.

 

i am thinking i will do best with two switches in series.one off/Mom and one on/off

And all the rest ? 

 

 

This is the image i used to get my head around it 

wiper.gif

Then you want to keep 2 permanently live this is park switch then switch 1 which is the run connection 

 

Live 1 = 53 Live 2 = 53a

 

Could get just a Mom/Off/On.

Make sure you agree before you go buying stuff :)

Could get away with a simple SPST just means you cant use the momentary function do do a single wipe you would have to toggle it on and off to get it. 

 

Or as you say put a mom in parallel to a SPST

HI  you don,t say the age of the vehicle but on early three wire motors they worked by switching to earth. There was one fixed earth sometimes marked E, one switched live via an ignition supply usually terminal 2 and terminal 1 was switched to earth via the wiper switch, this was for single speed motors and I think in the two speed set up a third brush was fitted in the motor and the second speed switch possition put 12v onto it. Wiper wiring can be confusing but you have to remember its the switching to earth. The self parking works internally on the motor by open circuiting the internal earth return once the switch earth is removed by turning to the off position.

I hope this helps you understand the wiring setup.
