Thread: Rectifier Problem..
02-12-2008, 04:24 PM #1
Have any the forum members had any experience of a rectifier going bad on an Efi ski..??
Basically i'm looking for a description of issuses when a rectifier goes tit's up..!!!
Pulled mine out today after the ski was running like a dog yesterday.. got a code 19 fault on the MFD..
Turns out, One of the pins on the rectifier was corroded to shit...!!!

Had the same problem... It melted like a birthday candle... The way the rectifier sits allows the plug to get wet and hold water in it like a cup... There was another thread on here with the HONDA part number and pics to replace your plug if your rectifier actually got to the point of burning up... If you cant find the other thread pm me and when I get home ill shoot you the part number... Check your fuses too...there probably blown

Yeah i dug that thread you were referring to up will having a search on previous threads..
There's really not that much about rectifier issues at all..
Certainly nothing that describes how the ski is or would be behaving when its fuc..... eh.? faulty..!!!
One of the other issues that has me concerned is the voltage was dropping like a stone.
About .1 of a volt every 10-20 seconds when it hit 8.5v the ski died..
Got it beached and swapped batteries with my buds ski (04 gpr) his battery is 3 months old max
That also started dropping like a stone was showing 11.5v within two minutes again code 19 on the MFD..???
The ski was still running like a sick dog with the fresh battery..???
I had thought with the fresh battery in the ski, it would perform not unlike a total loss system would..
There's no way it would have lasted more than half an hour or so..
The warning light and buzzer came on with-in 1 minute of putting the new battery in..???
I'm sure someone must have some input on this problem..??

Mr Quad, u didnt use the search finction, now did u
Heres the topic:
Your symptoms are correct. With a fully charged battery and the bildge pump disconnected, i had 45mins of riding time on a freshly charged battery. If i stalled or stop, I would be impossible to start it again.
U can not start a gpr when the battery has less than 10 volts.
Measure the voltage of the battery when the ski is running when the rectifier is working normally the battery will have a voltage of 14 volts.

Mine went a few month ago. Didn't get any fault codes the ski just stop and the wiring loam was on fire
When I fixed the wiring and fitted a new rectifier, I put a volt meter across the battery to check things. With the ski not started it was something like 12.4 V but with the ski started it goes up to 14.4v which is just the same as on a car when the charging system is working correctly.
With you voltage dropping I guess you have a prob there with the charging/rectifier where it's shorting to earth to create such a quick drain on the battery.

The fuel pump will run the battery down with no charging system.

Good point WFO..
Never considered the fuel pump.. add that to the bilge pump..
Then there's the juice required for the spark and the pulse for the injectors, plus however many sensors..??
God damn flux capacitor these suckers need..!!

I found it quite odd that my dealer had both the after market plug and rectifier in stock. Its such a random part to have for a place that doesn't stock head gaskets... Kind of makes me wonder just how common it is... Its deffinatly a salt water only problem. My ski was pretty close to stock when it burned too. As funny as i always thought the fire extinguisher was... I actually had it in my hand for the first time in 10 years of owning skis.

I have a spare rectifier if you want to buy a used one and not pay $170 for a new one.
