2004 Instrument gauge issues, it’s not the Gatew

Maybe this will help.

Yep, the ballast pumps still work.  

Hey Gibson1525, do your ballast pumps still work? That is the other weird thing. When I put my circuit breaker box, gateway and dash in my buddies boat his ballast pumps would come on. Mine will not come on in my boat.

Does anyone have a full boat wiring diagram? I looked on planet nautique but only see diagrams for the 40 pin and some dash items (mostly SE version).

I think my next step is to get some duetsch connectors and start redoing connections and running jumper wires to see if I can get them to fire up.

My buddy with the 05 changed out his capacitors and stepper motors in his gauges and now has all of his gauges working. It may be what you will need to fix yours.

Warning, long post. But, we learned a lot yesterday.

I went to my best friends house yesterday. He has a 2005 SAN 210 and is having gauge issues as well. Since we had both boats there we decided to trouble shoot both our problems and at least leave with one good boat.

My boat gauges don’t light up, turn on any back lighting except the ballast tank gauges. They are just dead. We checked and we are getting voltage to the bus wire plug on my boat. So, we figured bad gateway or bad gauges as well. Not so fast….
my buddy has a brand new old stock Gateway that he came across as well. Just a little piece of gold sitting in his garage. We changed out my gateway with the new gateway thinking this was it.. Nope.

So, now we decided let’s swap some parts between the boats. We took off my dash and put it on his boat with the new gateway. Boom, all gauges, lights, work except the oil pressure. But, it works on the digital display to scroll through. With his dash on and the new Gateway he still has the same problem he had before where nothing lights up or powers up.

We decided to take my old gateway, my dash, my circuit breaker box and put it in his boat. All gauges still light up except the oil pressure gauge which is a faria replacement gauge. So, it may be the gauge is not compatible.

Has anyone found a particular wiring issue that fixed their boat? What I do know is that I have a good Gateway, good circuit breaker box and all of my gauges work except the oil pressure gauge. I also know I’m getting good voltage at the bus wire to the gauges.

next we took the 3 position switch apart and I alligator clipped the non bilge wires together and I still don’t get power to my gauges. We also changed the two 30A slow fuses under the back seat. We checked the fuse back behind the throttle quadrant as well. I’m stumped but at least I know that my Gateway and most of my gauges are good. Does anyone have any idea where to go from here? Thanks
