Volvo Penta EVC issues.

[myultrasound]

Hi all..

Just bought the boat.

Single Volvo D3-130

EVC helm gauges:

Voltmeter only has a very small blip when I turn the key. Registers no volts.

Trim gauge sits at -5 and doesn't move whether drive up or down, no green or red light.

Orange flashing triangle. 3 beeps on key switch and electrical system fault shows up on the LCD display.

The drive will go up by the morse control switch but not down.
I get no signal voltage from the HIU for the trim down. But I do get a signal voltage for trim up.

The leg will go down using a jumper at the relay.

Is my HIU fried?

Can anyone shine some light, anything I can try?

Many thanks.

The suspicious in me says this is the reason the boat was for sale.
Seems a bit coincidental that the problem only occurred after you bought it.
I would suggest don’t start to fix it but check out your rights
There are some really knowledgeable people on here who can advise.

Hi..Thanks for the reply.
The boat has been sitting for two years and I did buy it as-is. Its a bit rough.

I'd just like to see if anyone can help.

Many thanks.

Has the possibility of like an almost dead battery been eliminated ?

 

[myultrasound]

Various new batteries have been tried.

Thanks for reply.

Thanks for reply.

@Momac is on the most logical tack. VP electronic engines are very susceptible to low voltage which can also eventually fry the ECU.
Odd that you have tried “various” new batteries. Have you really bought more than one set of new batteries?

Hi.. Talking to me like I'm a lying 4 year old?
I didn't say I "bought" various new batteries.

So, here goes..Explanation about the batteries.
I told the sellers (Jenneau Noirmoutier) If it starts I'll buy it. They put a large battery and got the engine started, then took their battery away. Got the boat home, I don't have a battery, called a friend and he has a new 90 amp battery to lend me while I'm tinkering. I bought my own 90amp battery yesterday, and gave his back to him.

I'm still thinking the HIU has given up.

Regards

Jon

How large was the battery the dealer used to start the engine????

Please dont take offence.
It is sometimes difficult on the forums to judge the "timbre" of a reply from the text on the screen.
This forum is a valuable vast vault of hard and expensively gained experience freely given .
Would suggest that every single poster on this forum has been in your boat shoes at some point and still got the financial scars to prove it.
Some of us even after far to many posts still come on here to find help when all else has failed.
At the very least it can suggest which blind alley not to throw any money up .
The fact the boat has been standing might suggest nothing more intially than a wire brush some contact cleaner ( not WD40) plus good earths and cleaning all and any loom connection blocks .
Off to my boat later , to find out why all my navigation lights are mysteriously coming on when they feel like it....... but not when I actually need them.
This will reduce the list of boat jobs to do under to 99.

What else did the dealer do to get the engine started? was it literally a new battery, turn the key and it started? If that's all they did, there's something wrong with your battery (or its connections) if it's not starting for you with your new battery - which if you have since tried 2 batteries makes this unlikely.

I guess then it's possible that they also swapped in some components off a nearby boat to get it running then swapped those back before selling it to you, without telling you the full story of what they swapped. but it doesn't make sense that they simply put a new battery on and it started, but when you do the same it's dead.

Guess you need to borrow an hcu and try it out, or speak to the Dealer and ask what else they did to make it run.

He has not said it won’t start , or have I missed something , some four year olds do have short temper .

Hi all... Just to be clear, the engine does start. No problem with that.
My issues are that the drive wont go down because working back, there's no 12v signal from the HIU. Electrical System Fault on the screen and some gauges not working at the helm.
I will look again for any wiring or connection problems.

I will get onto it again tomorrow.

Thanks !

Dont forget to apologise as well.

 

[myultrasound]

Apologise?

 

[Seastoke]

Apologise?

If you don’t know , that explains it . Goodbye.and good luck.

Hi Jon

If it cranks and runs and also trims up then I'd suggest whatever battery you are using is good.

Can you send a photo of the dashboard, specifically the control panel for the engine. Can you also confirm the 10-digit engine serial number, as this will help identify the EVC generation.

From that I can assist with a few steps to try and isolate the issue, and from that hopefully assist with ruling out the HIU as the cause. We also have some test equipment for the D3 which I could loan if you are in the UK as this would also help prove a point if the HIU is suspect.

Look forward to hearing from you

Hi.. Andy..
That's very kind for your offer to help. I have now re-fitted the HIU and taken some pics of the helm. I had a spare brand new volt meter that I tried and but still reading zero volts on the gauge.

I was thinking maybe the link cable is faulty but what I find baffling is that I don't see any 12v down signal from the HIU wire to the trim switch. I do see a signal from the HIU to the trim up switch. Also, whether the drive is up or down, the trim gauge stays at -5.

Many thanks in advance...
Jon

have you tested the volts at the battery when it is running ? Assuming this is a 12v boat it should be 14 plus volts.

To me this is power related. It says electrical service required. Find out what this means from the manual. Volvo have no customer facing support. It is all via the dealers who are variable.

Logically it is saying it has found a mismatch of volts somewhere which it can't reconcile.

What is the voltage powering the control unit when the engine is running.

A poor earth somewhere would be the prime candidate or a faulty alternator which can be confirmed or otherwise by the volt test above.

Hi jrudge...
Good point, I'll see what volts I'm getting at the HIU tomorrow morning.

Er, just re-read your last paragraph. There's no alternator on the engine. It was seized. Just waiting for new one to arrive.. I've not run the engine for any length of time without the alternator. Just started it up for a few seconds.
