Re: Dual 90hp Etec's

Just further feedback on my charging issue...

 

EVSoftware indicated exactly the same parameters for both motors, however, battery voltages were shown as follows:

 

Starboard motor - 11.6 volts @ 1500rpm

Portside motor - 13.8 volts @ 1500rpm

 

All other voltages, amps and everything else were almost identical between the 2 motors. Exept the above.

 

The technician is currently still investigating.

If anyone could possibly have an idea as to where to begin to check, please let me know.

 

Thanks

Re: Dual 90hp Etec's

Hello all - as said earlier, all parameters per the EVSoftware are correct according to spec.

The only reading tthat does not correlate, is "BATTERY VOLTS". No matter the RPM, reading to battery remains as battery voltage only. In this case, 11.6 volts. No charging increase whatsoever.

Charge Fault Indicator on EMM switches off after motor has started.

 

And thank you all for your help. It is much appreciated.

Re: Dual 90hp Etec's

Just further to my charging problem....

It seems the fault have now been identified and it seems that the regulator in the EMM has popped.

How this happens overnight with the boat switched off, is beyond me. it seems that the EMM will have to be replaced.

 

Anyone know where I can purchase a new one and have it DHL to South Africa?

Re: Dual 90hp Etec's

Just another interesting point. The service/repair manual states - "should the battery drop below 12V, between 500 to 2000 RPM, a fault code 26 will be logged and the charge fault LED activated".

 

None of the above actually happens. No fault codes or LED. Motor runs/acts perfectly normal.

 

Could  this possibly be something else than a fault with the EMM?

 

 

Thanks

This is the exact reason we suggested to test the charging system using an ammeter, load bank, and voltmeter per the factory service manual before condemning expensive parts.

Re: Dual 90hp Etec's

Once again, thanks for all the interest in this topic.

We have done the same test with a brand new battery. Results are the same. Battery fully charged to 12V.
Connected to motor. Motor run at 1500RPM. No increase in charge volts to battery.


Did the same with the other motor. Charge volts increase to 13+ at same RPM.
Remove the EMM and connected to the other motor. Results identical. No charge to battery.
It seems that the regulator/rectifier has popped. EMM will have to be replaced.


Who can help with shipping one to me here in SA?

Re: Dual 90hp Etec's

Hi Bill

 

All possible tests have been concluded and the opinion remains that a CAP in the EMM has popped.

 

I would like to talk to someone that could assist in shipping a new one to me.

 

Would anyone know of anybody I could arrange this with?

Re: Dual 90hp Etec's

Hi David. I have the same issue as you had. I also have 2 90hp etecs 2012 models. I was wondering did you ever solve the problem? Or did you find a reasonably priced source for a new Emm? The charging electronics on these motors does not seem to be very robust. If I can get a new Emm I am going to attempt a repair on the old one.

If your dealer has not contacted Evinrude support to see if anything can be done to help alleviate the cost of an EMM, email your serial number and a brief history of the motor to  http://www.brp.com/en/forms/contact-us.html
