Do you think it would be ergonomic to use the screen UP/DOWN switch on the RH handlebar switch from an Exec as a cruise control ACC/DEC switch on a non-Exec?

I'd like to know if it's awkward to hold the throttle steady while operating the switch.

My cruise control doesn't have an input for a cancel switch anyway, so I would have the functions I need.

Of course it would be sweet if a push inwards, like on the indicator switch, would switch of the cruise control.

It's not awkward I do it all the time.

I agree. I have no problem holding the throttle steady while using the windshield switch.

 

[ErikDK]

Thanks a lot.

I proposed a price and bought a new switch for 71 Euros on Ebay including shipping, list price is 101 Euros.

Somewhat expensive, but completely stealth, and easy to operate, according to you.

I'm not sure if it's waterproof enough for the cruise control electronic circuit, but if that should pose a problem I can always insert two relays in the circuit.

I think I have an idea how the starter switch could double as cancel switch, even though it will flash the headlights in the process.

Cutting the cruise control supply would purge the set speed, so it needs to operate on the brake sensing circuit, and flashing the brake light once is not misleading, and would also occur if I only apply the brake to shut off the cruise control.

Can somebody please explain how the screen relay works ?

Are both coils really energized at all times, except when you push "up" or "down"?

 

[MJR]

Both wires to the windscreen motor are normally grounded through the relays normally closed contacts to the B/W wire, when you press the switch one way it turns on one coil on applying power to one wire (G orR) of the windscreen motor, applying to the other turns on the other wire (G orR) allowing it to move up or down by reversing polarity on the motors wires.

 

[ErikDK]

I've looked a bit more.

Assuming ignition is on:
Both coils have constant plus, and they both have ground when neither up or down is pushed.

When both coils are hot both motor leads are connected together and to plus. The motor is acting as a brake.
When one of the coils are turned off, the corresponding motor lead is connected to ground, and the motor operates.

When ignition is off, neither coil is hot, and both motor leads are connected together and to ground. The motor acts as brake in this situation as well.

I'll need a score of relays to invert the switch functions to my cruise control needs.

i see what you mean, leave it to Suzuki to do it that way instead of having the relay at rest and just switching it on instead of off, lame especially considering a relays cycle life.

ABS light as "cruise on"

Here's the wiring diagram for the "Engaged LED" of my cruise control switch assy.
Since I will be using the screen switch from an Executive to operate the cruise control, I will miss the "Engaged LED"
However, I don't have ABS, so the ABS warning light is vacant in the combination meter, and could be used for this purpose.
How do I get the cruise control to switch on an 1.4W 12V bulb instead of a weak led?
the 1.st resistor is 680 Ohm, the second 100 Ohm, the transistor is a PN2222A.
I've calculated a current of roughly 15mA through the diode (13 V -(2*0.7V))/780 Ohm, is that in the ballpark?
I'm looking for exact components, not general ideas, but please educate me.

Re: ABS light as "cruise on"

Bonus info:

The ABS control lamp gets constant 12 V like the other control lamps, so theoretically if I could find a LED that fits the socket I could just connect the negative side directly to the "engaged LED" output of my cruise control.

DHL delivered the new switch today.

To boost motivation, I made a "CRUISE" label and stuck it on.

Re: ABS light as "cruise on"

Now if I could only change the red "ABS" symbol to this green cruise symbol:

Thanks to the mod for merging my two threads.

I've found the recepy for changing the ABS symbol to a "CRUISE" symbol:

A great project Erik.

I had to move some of the terminals around in the 10-pole connector, since the Standard has 2 wires, Grey and Pink, from a contact that works in reverse of the hazard switch and is connected to nothing and two wires, light green and black, that serve a function, in a separate 2-pole connector.

I end up with a 10-pole connector with 2 vacant positions and a 2-pole connector.
Someone at Suzuki had a brainfart when they engineered it that way.

Time to play with the instrument cluster.
I have a foil cutter at work to make signs, maybe I can make a template to scribe away the black material to form the "cruise" symbol. A green LED and a lamp socket, and I'm nearly there.

I may have to do this myself since I don't have the anti theft feature so can use the real estate for an indicator. Nice project so far! Though being that i have an exec, it'll just be an indicator with the controls mounter under my left handgrip.
