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 ?

Various new batteries have been tried.

Thanks for reply.
