Using Candoo and maybe found the reason: Battery Voltage Too High!! How to fix that?

[brobertov8]

Hello All,

Just got the CanDoo Pro out of the box today, and looks like it is already did help me.

Please find attached these two erros codes on the screenshots below:




First one: Battery voltage too high!! Could this be the reason of "warning flashing light" above 6000rpm??? I believe yes, because it match with the rpm on the screenshot. What could cause that?? How can I fix it, please?

Second: Temperature too high.... Yes I got twice these warnings and went to limp mode... Could be that 3 holes on the J Pipe??

Or the second error was due the first one?????


Any suggestion would be very appreciated.

Thank You,

Could this thing be the reason of the "battery voltage too high" and maybe also that issue related to high temp?

I think you and I may be having similar problems, I'm certain that my regulator fried but I'm not sure why.

Bro, your regulator is shot:

From the manual:
Rectifier/Regulator
All Models
The rectifier receives AC current from the magneto
and transforms it into direct current (DC).
The regulator, included in the same unit, limits
voltage at a maximum level (14.5 to 14.8 volts) to
prevent any damage to components.

See page 562: http://www.sea-doo.net/SHOPMANUALS/PWC/2004/smr_2004_lineup_a.pdf Section 12 provides detailed instructions for isolating problmes with the charging system. I suspect the second fault will go away when you fix the charging system ... even the second fault refers to an over voltage condition.

Exactly! I believe we have similar problems!!

Can I ask you where the rectifier is located on the hull? I will remove it after do some tests on satudary.

thanks

Thank You for a so detailed explanation!

Perfect!!! I also believe the second fault will go away!!!

I will perform the tests according to the manual, before change it!! but I cant agree more, it should be toasted (rectfier)!!

Thank YOu a lot! I will post the results!

Sometimes regulators just fry, unfortunately. A partially discharged or shorted cell in your battery can cause this too, this circuit is not meant to charge a battery, just recover it after restarts.

If your battery doesn't measure at least 12.5V it's either discharged or has a shorted cell, don't run your ski unless the battery is in good condition.

While you're at it troubleshooting the rectifier/stator circuit, be sure to measure the stator resistance to ground, there should be a complete electrical isolation, sometimes they can become shorted to ground which causes the charging circuit fuse to blow.

But if your system voltage is too high, it's b/c the regulator/rectifier is malfunctioning.

I cleared all the errors code on candoo and went to test it today. After a while, above 6000rpm... warning flashing light came on...

Went to home.. and checked again: error code again "Voltage Too High".

Then I cleared all errors codes and went to the water again, with a volt meter connected to the battery... and confirmed: Above 5500rpm I got 15,5v and at 6000rpm 16v or more...
Then I stoped the ride and I realize that warning light flashing was for the "too voltage" since it occurs exactly on the situation of high voltage.

Just bought the new rectifier and waiting for it arrives. I believe (and I wish) the warning light will go away with the new rectifier.

So that "warning flashing light" it is not just for oil pressure and low fuel... could be a lot of things... like on this situation too high voltage (almost sure).

Thanks

As I said, your regulator is shot. While you are waiting for your regulator to arrive, I'd encourage you can read up on your ski in the owner's manual link I sent to you. Understaing how the ski's electronics function will be a great help when using your Candoo scanner to troubleshot problems.

In the manual, you will learn helpful things like:

"Message Display
The information center features a display
area that blinks a message whenever
one of the following circumstances
occurs. The abbreviations between parenthesis
here are the code displayed:
• engine overheating (H-TEMP)
• low oil pressure (OIL)
• low battery voltage (12V LOW).
• high battery voltage (12V HI).
• low fuel level (FUEL-LO)
• maintenance reminder (MAINT)
• check engine (CHK ENG)
• sensor failure (vehicle electronic equipment)
(SENSOR)
• invalid safety lanyard (KEY)
• safety lanyard, learning key active
(L KEY)
• end of faults (END)
A beeper will sound depending on the
fault occurring to catch the driver attention
when necessary."

Thanks a lot for your suggestions.

Actually I read the manual in details during a boring flight. The problem is any of these codes did not helped me.

1. The manual does not say at each circunstancias the warning light flashes;
2. I did not get any error code on the cluster, except a "A-TEMP" which is not explained by the manual as well!

Any way was helpful for test the voltage and to know how much volts it should read at each rpm.
Also it would be helpful to test the oil pressure if it would be necessary (hope not).
I will post results.

if you have any tips about the two points above, please feel free to help.

Cheers

Here's the phrase you're looking for "whenever
one of the following circumstances ..." and then it goes on to list faults that may be displayed. So, if you have an overvoltage condition, the information center flashes, and you'll hear a beep. Overheat ... same; low oil pressure ... same, and so on. In your case, A-Temp relates to the temp sensor; not that it's a bad sensor, but rather that the voltage it too high which is caused by your regulator problem.

As you showed us in your first post with the scans from the Candoo (2d picture), your temps sensor doesn't like having 16VDC thrown at it. The scan actually says " ... or voltage it too high".

I agree, the root cause for the warning light is most likely the regulator not functioning properly, the battery voltage is becoming too high.

Guys you were correct.

Just changed the rectifier and voltage now is ok at any rpm.

Best part: No more warning flashing lights! COOL!

Almost complete all the repair service, only left one issue... I will open another thread.

Thanks
