Electrical issues utopia

[Crocket]

I have a 2006 utopia and I started having electrical issues. My stereo, bilge fan, 12v outlet and wheedles system stoped working. Every thing else works fine ( lights, horn etc), The fuses are good, I have 12v across all the fuses and the 2 20 amp fuses are good by the battery. I have no power at any of the listed components. I'm stumped where to look next

The problem might not be with the 12v side, maybe you have a bad ground? Check resistance from the negative wires of the non-working items back to the battery negative terminal.

I was thinking the same thing dsm, I have been trying to find a wiring diagram of the utopia but unable to find one. I put my wife's skis in the locker that night then the next day on the water is when I noticed things weren't working

I have the EXACT same problem and the shop manual does not have a schematic. I tested the the blower switch and it doesn't get 12V. Blower works fine when I give it 12V from light switch. I changed the Twin Engine control for a new one and same issue.

What is the really in the dash for? It seems like it is wired to the ICS and Blower switch. How do I test it? It is not even listed in the shop manual or parts.

I would love some schematics.

I can only find schematics for the challenger and speedster, I am going to do some wire chasing tomorrow night and see if there is another fuse. I’ll see if I have a relay

Pretty sure you have one tie wrapped to the main harness. I have seen references to it before but can't find any now.

Currently having a ground issue on my boat. Not sure about the Utopia, but most of the grounds go through the boat's ECU. It has been a frustrating problem to say the least.

ECU or VCM (One in the dash)? It also commonly called a Twin Engine Interface.

If the component is controlled by the ECU it switches the ground, 12+ is always supplied and present. Things that you control ie: lights, bilge pump are run through the VCM and switch 12+. The VCM is a second fuse block.

I am having a similar issue with my 2007Utopia, the only switch that works on the dash is my stereo. No horn, bilge pump, nav lights,or blower
checked grounds,All fuses are good that I have found so far.
checked 12v at the switches and all seems good.
any suggestions Would be helpful.
cant seem to find a wiring diagram for Thor this year and model again any suggestions would be gratefully appreciated.
I’m stumped

 

[Mister Magoo]

All of the components you are having a problem with run through the VCM. There is no way to troubleshoot the VCM other than to verify the correct voltages going into it and not coming out of it.

 

[Rogermrowe]

Where is the VCM located In a 2007 Utopia?
Does anyone have a wiring diagram I could possibly use to verify the correct voltages?

The VCM is located under the from dash, you should have a small door that swings open to reveal the VCM and fuses.

Please PM your email address and I will send schematics.

I fixed the issue, turns out it was 1 of the fuses behind the battery cut off switch. To access, remove the switch and look around in the hole for 2 pigtails. The fuse is located in there.

If your gauges aren't working, check the rear ECU boxes for each engine. There is gauge fuse in each box.

I located and fixed my problem.It was the 20 amp fuse behind the Battery cutoff switch,there are a total of 4 fuses behind this switch I initially found and checked 3 Fuses didn’t see the problem one.it sure would have been easier to troubleshot with a schematic,I would still like to get one if anyone had one they would like to share,PM me.
This was definitely a learning experience. In my troubleshooting efforts I located a total of 16 fuses in this boat and of course the last one I located was the culprit.

Wow, in only found 2 there.

PM me your email address for schematic.
