low 12 volt warning 2003 GTX 4-tec.

i just bought the boat this year and it was serviced and a new battery placed this spring. it runs great and starts up fine. I am not adept at self service. Is it safe to run? Will I get stranded on the lake?

Next time it gives warning press start/stop button to stop ski then press set 5x see if you get any codes it may also be a bad rectifier easy to replace

thank you. no codes came up so does that support or not support replacing the rectifier?

 

[Schnitt]

You got it mine did same exact thing I ran ski a few times then replaced the rectifier these skis are computers on water pretty much

Usually,,,rectifier.

 

[DAW67]

thanks for pointing me to the likelihood of this being a bad rectifier. Should I buy the OEM (expensive) or is an aftermarket replacement Okay. And if aftermarket, can someone point me to a good aftermarket brand or seller?
thank you !!

As an added footnote,,,inspect the yellow stator coupler at the back above the stator,,,often the "handshake" causes resistance over time,,,the wires can turn dark,,,and even melt the insulation,,,so before buying a rectifier,,,check that you are getting a good 25 and plus AC volts from each pair (3) as you rev it,,,

thank you! are you able to direct me to a step by step on how one tests the rectifier and stator?

 

[POPPS]

The stators rarely go,,but that handshake coupler gets hot over time,,,i would have a look at it,
To test the rectifier, you can do it at the rectifier,,,remove the red/black coupler,just put meter leads on the red / black pins,,start it,,,and check that is charging 13 plus volts
To do it at the battery put your 12 v dc leads on the battery terminals,,, Start it and check for 12 plus volts dc.
I chose which of the 2 situations are easiest to access,,they vary from model to model,,year to year.

Thank you, POPPS! appreciate you helping me (a novice!)

 

[DAW67]

well I am back for more advice. I have the replacement part but can't find where the rectifier is in the ski! its a 2003 GTX 4-tec. i was hoping for "plug and play"but evidently not :-( Any direction to finding the rectifier will be appreciated

 

[POPPS]

No worries, it is p&p,,,follow the 3 yellow srator charging wires...to the front of the ski,,,yours may be at the front,,behind the storage bin,,you will see the plug...make sure you get the exact one..i had an aftermarket this summer and the plugs would not marry,,,they try to keep the rectifiers in a cooler place,, so up front..away from the motor.

My rectifier is on the air intake box, right next to the air intake on my 2007 GTI SE 155. Black box about 3 inches square, 1 1/2 inches high. Smooth top. I just bought the replacement rectifier from the dealer today for $205. The new part has cooling fins on top of it. Putting mine on tomorrow, hoping it resolves my low 12 volt message and slow crank after riding a couple hours. I don’t seem to be charging well on my ski, although the dealer said it was charging fine. When it gets hot, I think I lose some charging ability, after starting fine to start the day with a charged battery.

 

[DAW67]

I found the rectifier and replaced it. Just where you directed me to look: up front. I removed the hatch access panel and there is was. YEAH!
Oh- but it didn't clear the warning of 12 volt low. :-(
The stator wires look good.
My next step is, I guess, to get a volt-meter and test the new rectifier, battery, and stator. I appreciate any further suggestions.
A related question: the ski starts easily. will i get stuck on the lake if i don't stop it except at my home dock?

 

[Milehighguy303]

I realized that the cooling fins are down in the air box, where the air intake can help cool the rectifier… the smooth bottom of the rectifier is what you see pointing upward. I hope this helps my battery charging. My stator wires all look good too.

Make sure you charge your battery first, before condemning the stator. From experience, the ski can start to run poorly if you don’t have sufficient electrical battery. I haven’t had my ski stop, but I have seen it start and Idle ok, but not be able to accelerate well with increased load.

thanks. the aftermarket rectifier I bought only fits with the fins up. The battery is still good. I was able to exclude that as a problem but I am going to need some help with determining where the fault is. Problem is, my local shops have weeks waiting times for service.
