Anti Dive elctrical disconnects

[Silverado6x6]

I just purchase that timed relay and socket just to try this out, I like the AD feature on my 89 and I'm not quite ready to change my front springs yet.

Just an FYI.

Both of those ebay time delay relays have contacts rated for 3 or 5 Amp, 250V AC resistive. Switching 12V DC inductive will be very hard on the contacts and they may not last long. The 3A will fry pretty quick since we are already over that.

It is a lot harder to switch DC than it is AC, it is also harder to switch an inductive load than a resistive load. I can see these not lasting very long.

 

Now on the other hand, what might work for this is the time delay relay that some are using to delay the turning on of their headlights and use that to control a second relay to switch the AD circuit. I'll look for the parts and post a wiring diagram if you need it. I might have to do this for myself.

It is even easier than I thought.

Just wire in this relay, in series with the EAND relay that is on the bike now.

The EAND relay is located behind the instrument cluster under the dash.

 

Relay Wire

Terminal - Color

30 - White (from EAND relay)

85 - Black (ground)

86 - Yellow (to yellow of EAND relay)

87 - no connection

87A - White (to AD solenoids)

 

This will activate the AD for 10 seconds after you hit the brake and then turn off. If you pulse the brake the time will start over every time the brake is activated.

 

The contacts are rated for 12 DC at 30 amp so contact rating will not be an issue.

 

NOTE - This relay is polarity sensitive. Pin 85 must be to ground and 86 must be to +12V or it will be instantly turned into a desk curio.

To make correct connections

Why not a secondary 20a 12vdc relay like a Bosch for driving lights after the timer relay?

I use those a lot.

This is the same 30A bosh type relay but they open it up and add a time delay circuit and seal it back up. No need for another relay in this case.

What does that wiring diagram indicate?

Can you label the pins for me, I had an associates in ELT and worked around EEs on various projects as a software engineer for many years but I just don't recognize the facilities denoted by that wiring diagram?

Hope this helps.

It's the diagram itself that doesn't make any sense. I've looked at a couple of representations for schematic symbols thinking maybe my "vocabulary" was not up to date but I still don't get it. It does not look like relay contacts and when you said don't connect 87 which I thought would be the flipper or output it makes no sense at all unless it's NO and either connects +vcc or gnd to the wire between 30 and 87A depending upon input, but where is the input terminal?

[Flyinfool]

OK now that I am in the middle of typing out the explanation for how this works I can see where I was a little off in my previous post. I will go back and edit it.

 

This relay is a SPDT (Single Pole Double Throw) Most relays of this style are SPST (Single Pole Single Throw) with the contacts normally open.

Pin 30 is the common

Pin 87 is Normally Open

Pin 87A is Normally Closed. (this pin does not exist on most relays of this style)

 

Since this coil is polarity sensitive.

Pins 85 is the negative side of the coil.

Pin 86 is the positive side of the coil.

 

 

So pin 30 gets the white wire coming from the EAND relay.

Pin 87A gets the white wire that goes to the AD solenoids.

Pin 87 does not get anything connected to it, it is not needed in this application.

 

Pin 85 is the negative side of the coil so it gets connected to the black wire which is ground

Pin 86 is the positive side of the coil so it gets connected to the yellow wire which is the power coming from the brake switches.

 

When you activate either brake, it sends power on the yellow wire.

This power will cause the EAND relay to close and the time delay relay to start timing but do noting yet. The EAND relay contacts will connect power from the brown Signal circuit to the white AD wire.

Since you are breaking the white wire that went to the AD solenoids and connecting it to the NC contacts on the TD relay that power will continue on thru the TD relay to the AD solenoids. Once the 10 second delay has elapsed the TD relay will energize which will cause the NC contacts to open turning off the AD solenoids.

 

 

NOW I should have you throughly confused...........I am........was...........is:whistling:

No, I get it. The inductor has the slash on the side and the active device is wired between 85 and 86. when the timer pops the inductor is energized and draws the iron core into the stable spot which throws the contacts to NO. Or at least thats what it looks like now that I've been told what it is. I'm just not used to seeing things, primarily the contacts, depicted in that way and it threw me. Do you know of a standard for this style of schematics that I could follow up with?

 

This is more what I'm used to:

I just now realized the pin numbers are standardized.

Twenty years ago, I belonged to the Venture Touring Society and we went through the same discussions. I disconnected mine when I got progressive springs and I never missed it.

Yep, the good ole VTS. Still have several run pins from them.
