Well, the 1st one lasted about a week, and then died. I thought, ok, it happens. I ran through their trouble-shooting guide, checking all voltages under the given combinations and everything checked out fine. I checked the little red LED inside the servo unit, and it would illuminate whenever I pressed either "set" button on the control panel or pressed the brake. I even connected my engine diagnostic meter to the coil lead to ensure that the unit was receiving a signal, and it was. I then popped the vacuum line off of the reservoir and it had oodles of vacuum built up. I stuck my vacuum gauge on the hose and it showed 10psi at idle and climbed to over 13psi at 4000 rpms.

So I purchased another with plans to send the first one back for repair and then sell it. I installed the second one, including the button panel, and this one has failed to function at all. I've performed all of the same checks as I did with the first, and everything checks out fine.

Ok Obi-Wan, what now?
 
Can you elaborate on "something isn't quite right in the setup on the bike". It's a very straight forward installation...
 
I wish there was, but after triple-checking everything, I seriously doubt there's something wrong with the installation. I get the correct voltages and LED indications, and even checked for the tach signal. I plan to contact Audiovox next. This is such a simple device...
 
I assume you do not have anything funny inline on your brake lights, what was it that messes it up, flashing brake lights?

I went though the same thing except my first was as your second DOA, ended up taking the whole thing off in frustration selling one of the two new spares I had to Forest, still have the second one (NIB)and one box full of spare parts(DOA) so if you want any spare parts to play with let me know and when I get home will ship to you. The folks at Audiovox pretty much cover the same things you have already done and had to eat the cost of the first one due to the cut and slash required of the installation. I guess the one forest got seems to be working fine. Good Luck

good luck
 
Tom,

The one I purchased from you was my second install of this model unit and it went perfectly. It's performing well.

Thanks

Forest
 
Like another post stated, do you have any kind of LED in the brake light system. That will cause the Cruise not to work. If you do, then you will need to put a relay in line with the wire that goes from the brake wire to the CC.

If all else fails, try is to unplug the brake modulator.
 
I have both headlight and taillight modulators installed. I turned off the headlight modulator thinking the pulsing was causing the voltage to fluxuate, but that had no effect. I wouldn't think the taillight modulator would be a problem because it's not generating anything until the brakes are applied.

Overall, if it turns out to be either the headlight or taillight modulator as the problem, I'll be getting rid of the Audiovox cruise control because the modulators are safety features I'm not willing to ride without. I'd much rather keep them and get a Vista Cruise.
 
Can anyone offer an explaination as to why having LED's in the taillight would cause a problem? Brake light bulbs, standard or LED, are part of an open circuit until the brakes are applied, so I'm not seeing where it would matter.

Put your brake light modulator on a relay and then you cruise should work. alot has been written about this subject. Try the search feature for more info. good luck.
 
Also, why did the first one work perfectly for a week with the taillight modulator installed?

I'm not trying to be difficult, I'm just trying to get an understanding about what's going on.
 
If it is a brake light issue with the modulator, the problem is when the brake light is off, not on. The modulator may be sending only a half volt into the brake system. Not enough to turn any lights on, but the CC sees that as the brake is on, and will not work. I have an LED bar, and my CC would not work. Put in the relay, works fine. I had a half volt when the brake lights were off, 12 when on.

I do not have a brake modulator, so I do not know how it is hooked up. Just taking a stab at this.

If it is a modulator, then you do not need to get rid of it. Just put a relay in.
 
Research reveals that taillight modulators seem to interfere, but I'm not understanding why. It's been posted to install a relay to isolate the brake lights. The question then becomes, isolate from what? Doesn't everything on the bike operate from the same power source?

Someone stated that the purple wire needs to see absolute zero volts when the brake is not being applied. I'll check that tomorrow after work. It sounds like the relay should be used to control the purple wire rather than the brake lights. It would make sense to connect the brake light wire to the coil on the relay and the purple wire to the switch portion of the relay so that the purple wire is completely disconnected from everything when the brake is not being applied.

Dang it! Now I'll have to wait until after work to try this!
 
I plan to disconnect the purple wire tomorrow to prove/disprove the theory. I really hope that it's something that simple. As I've always stressed to my two sons, you learn far more from your failures than you do from your successes. If everything worked perfectly the first time around, you wouldn't learn nearly as much!
