I found out my paddle wheel speed sensor failed. Here are the steps that the nice folks at Perfect Pass walked me through to find that it was truly failed.
Leaving the paddle wheel plugged into the PP Black Box turn on the key.
Using a pin and volt ohm meter (12 v dc). Check voltage on the red wire by using the pin on the back side of the paddle wheel input wiring clip. You need the pin because you will not be able to get your meter leads into the back of that really small wire harness connection. Should see some where between 11 and 13 volts.
Now place the pin on the next wire up which is the green wire. The green wire is the speed sensor wire. Using an alligator clip put your test lead and pin on the green wire so that your hands are free.
Pull your paddle wheel out of the hull by removing the holding pin. Easy to do.
Watching the voltage, rotate the paddle wheel 90 degrees. You should see the voltage change from either 12 volts to 0 volts or vice versa. Rotate another 90 degrees and the opposite should happen.
If you paddle wheel is failed like mine was, you will have 10.6 volts and as you rotate the paddle slowly, there is no change in that voltage.
At this point either the sensor itself has failed, or the wire between the sensor and the perfect pass is broke. Being very small gauge wire this is very possible. To make sure that it is not simple a bad wire, cut the wires about a foot or so from the paddle wheel. Strip them back.
Put the white wire to Ground -, Red Wire to 12 volts +, and then do the same test on the green wire. If the voltage pulses and the paddle wheel is working, your wire is bad. You could splice a new wire from that point back to the black box. If the voltage does not pulse then you definetly know the paddle wheel is bad. There is magnets and a printed circuit board in that paddle wheel. The circuit board must have failed.
So here is the kicker. I have a 2002 SN. the Paddle Wheel is somthing called st200. It uses a 1 3/4" hole in the bottom of the boat. It has been discontinued in favor of the st300 sensor which uses a more standard 2" hole. These sensors are manufactured by a company called Airmar. Not looking forward to making the hole bigger and putting in a new paddle wheel. Makes what should be a 15 minute project into half day ordeal with all kinds of bad potential consequences.
Great People at Perfect Pass. I should have called them a lot sooner. This whole deals sucks. Correct Craft bangs me for a $150+ bucks for new gauges because thier old ones suck and keep failing(Teleflex) and during the process, I find the paddle wheel that they put in is discountinued. I am sure I will be $500 bucks deep and a lot of hours trying to get every thing working on the boat. Which by the way already had the gauges replace once in 2004. And these gauges failed again in 2006. What do I do with these Teleflex gauges? Throw them in the garbage or try to get them warranted directly and then sell them to some sucker.
