2002 ski nautique

I just checked power at solenoid, there is a constant 12v but nothing on the other terminal when I push start.

Pull the cannon plug off the back of the main keypad and check for 12v on the pins in the plug.

Skier, Not to send you toward another dead end and others that are more knowledgeable will correct me but I am going to go out on a limb here and suggest 12.3 volts at the key pad may be a problem. And I repeat MAY be a problem. I would definitely think 12.3 should be more than enough but from what I understand 12.3 means the battery is only 50-75%. I researched PlanetNautique.com and found a thread posted by Pat-Oz ( in Australia), titled “Key Pad Not Working” from November, 22 2004. Apparently he had similar if not the exact same issues you are having. His lights would only blink while 1 and 4 were presses and the went out when released and had other similar issues. As you read through all the posts it turned out with him it was a voltage issue that was resolved after attending to his battery cables/terminals. Something to consider. On many older boats the battery cable corrodes inside the insulation and therefore can result in poor contact between the battery cable and the battery terminal connectors where the terminal is clamped to the cable. Also checking/cleaning the negative cable ground at the block isis important. Apparently the key pad can be very sensitive to voltage. A poorly charged or weak battery supposedly will also cause issues with the key pad.  Sincerely hope this information helps

Just for grins skier, put a battery charger on the batt and try again.

So if there is no code embedded then anyone can buy a keypad and take any nautique they want? 400 is a good price for your choice of nautiques... I hope there is something we are missing to unlock the new keypad. Thanks everyone for all your help, it has definitely helped me figure out where to look.

Don't see anywhere to hook one up

With the new battery I am getting 12.5 at the red wire and the exact same at the battery. I got a group 65 battery like it calls for. 750 cca and new ground terminal... I get the same voltage at starter and solenoid, just no communication from keypad, and no power at any other wire from keypad when I push any button.

No power out of either green or orange wire makes me suspicious of the key pad. I asked Jeff if he would check the voltage of the key pad wires on one of his boats since I am 2000 miles away from mine. I am sure he will be willing to help but has yet to post back to me. In the mean time I would be calling NautiqueParts and get their thoughts and if appropriate sending you a replacement.

I could be wrong but as a ballpark range a resting fully charged battery should be 12.6-12.8v. 12.9 and above is considered overcharged. An alternator puts out 13.7-14.7v. A battery charger initially puts out about 14.7 and the floats at 13.5 v. There are other poster on here that are a lot more knowledgeable about this than me.

I guess I'm going to box this keypad up and send it back for a replacement... I checked the wires again, and with 14.5v the orange wire makes the multimeter kick on very dim, not enough power to read but a very little must be trickling through it. That should be a sure tell sign that this new pad is faulty, correct? Or it has a code in it from factory and they have not supplied it for me?

Skier, you said when you push the start your “dash lights” come on. Do you mean the indicator light immediately below the # 4 button. If so you have entered “unlocked” mode. Which is a good start and what is expected since we can assume no code of any kind has been successfully installed thus far. In “Unlocked”mode and with the indicator light below button #4 “ON” you should now have power to the key pad to the right of the steering wheel and all function on that key pad should operate assuming your boat came with that option.

Yes that is correct. It must not be unlocking. I just checked PlanetNautique and no new posts there yet. Sounds like you have already contacted NautiqueParts for a replacement. Hopefully in the end you are the “one in a million” guy that gets the faulty key pad. If that turns out to be the case, buy a lottery ticket for a million dollar drawing. Maybe lighting will strike twice.
