Electrical Power Failure - 2020 G25

[Scottkclawson]

Hi Everyone,

I’m new to the forum and trying to get any help I can for an electrical power failure we have on our 2020 G25.
We were riding through some relatively choppy water and after hitting a bump the engine unexpectedly shut down. I then noticed there was no power whatsoever to the boat. No, horn, lights, anything.

Battery switch and connecting wires are in tact. tried to trip the breaker resets, looked at as many battery connections as I can get access to. Nothing seems to be lose or out of place. Safety shutoff button is in place.

Our dealer service dept can’t see it for a month and we really need to get it back on the water before then. Any suggestions to look at would be greatly appreciated.

Thanks.

Look for a breaker on the engine. I'm not familiar with the 2020 boats but nearly all of boats have a 50 breaker on the engine which will kill everything if it pops. I've had this happen a couple times over the years.

If like in previous years it should be mounted by the ECM and will be a red button.

Thanks so much for your help! I can't seem to find the breaker on the engine. I did find the fuse box by engine and checked and all the fuses seem to be good. Can you point me to where I should look on the engine for the ECM?

Thanks again,
Scott

Have another look at the big orange 30amp fuse in the engine fuse box. Sometimes it’s hard to see when they blow.

Is there power to the keypad? Linc system powers up? As you know when you enter your code the led on the keypad should light. Are you sure that that that the battery switch is intact? I think some people had them break. You pulled cover under dash, and took a good look at the back of it?

I don't think an engine fuse would keep lights and hort from coming on.

Scott,
Correct, there is not any power at all to the keypad, horn, etc... I did check under the dash, and from what I can tell everything is tight and in place...

Thanks, any tips to tell if the big ones are blown?

I would start there then and use a test light or multimeter and make sure you have power to the battery switch. Battery switch is positive.

See pic. Keypad get's power from battery switch. So if keypad not working then power probably not getting there from battery.

When I turn the battery switch from “off” to “on” I can hear a small click in near the engine. Which makes me think power is still getting there. Maybe just dead near panel? Trying to figure out how to attach pics I just took on my cell.

I think it's voltmeter time. Start at the battery and see what voltage you have there. Then go to the breaker in Scott's diagram and test for voltage on both sides of the breaker. Follow that to both sides of the switch with the switch in the on position. This will take you to the bus bar. If you end up with good power there you have something in the electronic circuitry going wrong like a bad Power Distribution Module or loose cable to one of them.

That a series of hard jars started this mess would certainly open the possibility that a cable or connector to one of the many electrical components could have been loose or not fully locked into place and has come disconnected. Since this is potentially a season ending event it certainly wouldn't hurt to start a one end of the power and nut and bolt everything. Start with the basics by insuring the ground cable to the engine and the power cables at the alternator and starter both look good and are properly connected. Work your way up the electrical system from there. Look for any loose wire connections, any cables that may be pinched and check all connectors you come across to ensure they're tightly connected.

Believe it or not it typically the simple stuff that ends up being the cause of issues like this.
