Audiovox cruise control Sensitivity setting

[MP]

For those who have the Audiovox Cruise Control, do you set yours at medium, as per instructions, or high, as a few have stated?  And why?

I believe I have found out why mine would not set.  My brake wire connection was not right.  The Audiovox sends a low volt signal down that wire, to see if the brake lights are connected.  If not, meaning no brake disable function, it will not set the cruise for safety reasons.

TIA,

Mornin MP.  I set mine by the instructions but haven't been able to test it yet.  I have to debug my brake light issue.  I've got a LED brake light and have done the relay mod; however, it still doesn't work.  When I get that taken care of I'll let you know what I find.

I have the stock lights, but I figured using the relay would be good, so would not have to worry about it IF  I did a\change lights.  That is where my problem is.

Instructions say you need a connection to the bulbs, as the Audiovox sends out the signal to tell if still connected.

But, how does the relay do that?  The purple from the Audiovox goes to a terminal on the relay.  But, when the brakes are off, that terminal is NOT grounded, so the controller would think the system is not hooked up right.

I am confused.  How does using a relay give a ground to the brake light circuit?  I am headed out to the garage to see if I can figure it out.

A suggestion, be sure to go to the back page of the instructions.  There is a trouble shooting guide there, to test the circuits.  Do that as soon as you are done.  Double checks if hooked up right, although I am thinking it will not tell you if a ground on the brake lights.

It's a "normally closed" relay. It's the opposite of what we are used to seeing. Therefore it is always connected. When you depress the brakes, the relay is opened.

I'm using a single pole dual throw relay.  One terminal is normally open and the other is normally closed.  First I'll make sure everything is hooked up correctly then I'll break out the multimeter and start checking.  I'm also not using the stock Audiovox switches.  The master power is on a Kury master cylinder mounted switchbox and the set buttons are on a Pingel switch.

I've got 2 Valks, both with Audiovox cruise control, and many thousands of miles on both. I've found that the best results for me (by far) are with the following dip switch settings:
SW1 - ON
SW2 - OFF
SW3 - OFF
SW4 - OFF
SW5 - ON (gives the best performance maintaining speed on hills)
SW6 - OFF
SW7 - ON
Also... leave basically NO slack in the bead chain connected to the throttle linkage.
And... the best relay to use is the "normally closed" SPDT 5-pin relay (single pole double throw) - wired as follows:
Purple wire fron Servo to terminal 30, Run a ground from both terminals 87a and 85, Bike's brake wire to terminal 86, terminal 87 is not used.

I think I used the wrong relay.  Mine only have 4 terminals, not the 5 you have listed.  I could not get it to work with the relay.  I hooked it up direct, per Audiovox instructions, and seems to work. Have not had it out on the road yet, as it is raining, 34 deg, with some snow flakes.  And I have 1 1/2 miles of dirt road to get to the highway.

whats the reason your were running the relay?

[MP]

I am planning in the future to do something to the trunk lights, for turn signals, etc.  Audiovox says that may cause problems.  Also, if use signal minder, or any of the other products like that, might be a problem.  They do not ground the brake light wire circuit.  Need to do that to get it to work.  Thought I would just be a step ahead?  Oh well, best laid plans.  Al least now, I know what I need to do to add the relay.  Especially use the right one!

I am using a MCcruise control, not an audiovox, but when it would not work with my Kisan Tailblazer brake light I just wired a conventional bulb into the harness under the right sidecover (black tape over the bulb) to add the resistance necessary.

[MP]

The resistance is not the problem.  The audiovox sends a low voltage signal down the brake light wire thru the ground for the bulb, to be sure the brake light is wired in.  If not, it will not set, for safety reasons.

Fudge, who're you asking?  If it's me I put it in my first post that I have a LED brakelight.  Since LEDs are diodes, they don't let the cruise detect a ground so you have to provide one that will allow the cruise to disengage when you hit the brakes.

To MP. But he cleared it up for me!

I have all LEDs on my I/S.  I used the SPDT (Single Pole Double Throw) relay (5 pins).  Coil is wired to brake light on one side and ground on the other side.  NC (Normally Closed position) connects the purple wire to ground.  When energized (Brake light comes on) it switches the purple wire to the opposite pole, which is also wired to the brake light (+12v when activated).  It says that the purple wire will float high (+12v) on its own if not connected, but decided to force it high just to make sure it cuts off when I hit the brake. 

Also... DON'T rely on those crappy crimp-on connectors.  Solder into the brake light wire to ensure a good connection and make the thing cut-off when you hit the brake.  Trust me on this!!!
