Charging question

[ucontrol]

I have a 2000 GTX RFI Sea Doo. This last week, the unit ran good for about 3 hours. Then it refused to turn over. The dash went blank when ever we pushed the start button. All the starter did was click. It stayed the same all day long and would not start. When I got home the unit started on the trailer. I pulled the battery out and charged it all night. It took a very high charge as the gauge read over 6 on the charger for over 6 hours and then started to drop down. Inthe morning it read about 2 on the gauge the next morning. I then took it to my dealer and he did a load test. He said the battery was as best he had ever seen and it was fine, reading 13.5 volts. He wants $130.00 to diagnose the problem, but he says it is most likely the rectifier. That unit is about $190.00. Do you guys think I should gamble and just buy a rectifier or have the dealer do the job and pay the dagnosis and then whatever part I need ? Thanx Steve rovnr@aol.com

Well... load testing a battery directly off the charger is going to give you a false reading... unless the battery has an internal short. Also... you shouldn't be using a charger that big on a PWC battery. a 6 amp charge will literally cook the battery, and boil the acid out. You need a small charger. 2 amps max.

Before you pay a dealer anything... did you check the fuses? there is a 15a fuse for the charging system on the MPEM. Did you check over the electrical plugs? Something could be loose, or corroded.

There is a good chance that the problem is the rectifier/regulator... but before you put the $$$ down on a new one... check the basics.

I am about to order one too. If you want to check out the below, this is the direction I am going.

Personally I think the rectifier you are looking at is overkill, too much money plus you will need to modify it and mount it outside the front E-Box. I bought one from this company and it's the stock size.

I might have explained my situation wrong. Thank you for replying to me. The battery in question was a heavy duty one, with extra power, in March of 2012. It is a sealed battery. The charger I am using is a 2/6 amp unit. It charged at a very high rate for about 6 hours b/4 it started to drop off. That, to me that indicates a dead/low battery. After leaving it off the charger overnite, I took it out of the ski and went and had a load test done. ( I did charge the battery in the ski, but disconnected) As for the charging fuse, I am not sure exactly where it is. I did check all the plug/wire connections, and they seem good. I have learned that the 2000 RFI rectifiers are not very dependable that is why I am leaning towards that. The ski is 12 years old, but it only has 150 hours on it. Is that a lot of hours? Should the rectifier last longer than that?
