PerfectPass won't engage

[sun-n-fun]

I have a 1999 Tige 21V with PerfectPass that has worked just fine for many years. All of a sudden, it simply won't engage. It beeps when the setpoint is hit, but does not take over the throttle. Any ideas what to check?

There's a servo motor attached to the throttle cable on the PP module (should be right on top of your engine). You need to run the Servo Motor Test. Here's the instructions on how to do the test:

Every time you return the boat to neutral when PerfectPass is on, the servo will wind in the cable until snug in a clockwise direct. This is the normal starting point for the servo.
Each time you turn the key on or start the boat, PerfectPass becomes powered and the servo will perform an “auto tighten” function and will attempt to wind in the cable to confirm it is in normal position. (If in proper position, it will appear simply as a “click”, “click”, “click”).
To check servo & servo power wire, with key off turn black knob on servo motor counter clockwise ¾ of a turn. Now turn key on and black knob should turn clockwise about ¾ of a turn as part of auto tighten. If it does, repeat procedure, except this time hold black knob gently to apply some resistance to auto tighten. If it rotates with good strength then it would appear servo & servo power cable are fine.
If it does not rotate or just vibrates, then a wiring phase coming to the servo may be loose or broken. Inspect all wiring around servo. Pull both white plugs apart at servo & inspect pins to ensure they are in place. Gently tug on each wire to ensure they are securely in crimp. Check at Master Module where cable is connected.

If you cannot locate problem, contact PerfectPass.

The servo frozen has frozen up and will need to be replaced. Try to twist the black knob and it should move freely. Yours is probably tighter than knickers on a Nun.

It's amazing what you can do with cut & paste

Actually, I had mine get a loose connection within the first 30 days so I actually did the test and found the loose connection. I'm ashamed to admit that I couldn't figure out where it was supposed to go. The guys at the Ski Dock bailed me out.

Hey - that's great information, thank you.

I did the test and no it doesn't wind the cable back up. I'm guessing that knob is supposed to turn much easier than it does on mine. I damn near need a wrench to turn mine. Guess I'm in need of a servo motor. Thanks again for the help - at least saves me a trip to the dealership which would probably take a couple of weeks to get an appointment this time of year.
