Gauges quit working.

I have a 2008 Dutch Star Spartan Chassis.
Recently all my dash gauges quit working. Also a transmission code came up (J1939) communication fault. Checked all the fuses I could find, they were all good. I might have missed some as I don't know were all to look. I'm wondering if anyone has had the same problem???

Hi and welcome to the forum.

I have removed the other thread you began on this topic since our forum rules don't allow duplicate threads.

Best of luck.

Welcome to the forum and irv2.
Have not heard of the Data link fault in the Spartan chassis as we use to get them in the Workhorse chassis numerous times.
May want to check your harness plugs to dash for one that maybe loose.
In this link there is a diagram of dash board wiring plus all your fuse locations in your DP.
Here is Brochure and Owners Guide for you and in my signature below are links to many others for your Newmar.
Safe travels and welcome to the Newmar family.

Check your battery cables - particularly ground. I had that happen intermittently on a previous coach.

Have you been driving through heavy rain? Are there other things not working like backup monitor, fan blower or other dash electronics?

Hi Grass Hopper,
Welcome to iRV2 and the Newmar Owners Forum. Gut feel says it is a connector or ground. There are quite a few connectors scattered around the chassis that could cause the problem. Consider giving Spartan a call (with the VIN). They can provide some guidance. For me, it would be a visit to a local Spartan service center.

Look around starter for loose connection. Don't ask how I know... Gauges are connected to 'Ignition' voltage. Your ignition voltage is not there or is very low, mine was around 3.3volts.

I had that happen also. My problem turned out to be the ground, but in my troubleshooting I also found that the speedometer is the master gauge and if that goes, the others go with it.

Gauges are powered by the engine computer. Look at the ECM fuse. Locate the Spartan fuse panel mounted on the frame rail in one of the storage compartments. The ECM is a 30 amp fuse. Also that fuse panel is protected by a 60 amp fuse at the battery. My reference is my K2 chassis on the Essex. I realize that you have a different chassis but I think the same should pertain to your chassis.

My gauges come on as soon as 'ignition' voltage comes up. And that comes up when the key is turned. You can measure ignition volts at quite a few places, in my front driver side compt there is a circuit board with two fused busses, one is 12 volts (battery) the other is 'ignition'. Spartan pointed out a fuse number all the way back of the coach in the 'Spartan buss box' (near my rear axles) where ignition voltage also comes up. And a third location was at my engine kill switch. In my case, ignition voltage was at 3.3 volts (gauges dead) and if I turned the kill switch to 'open' (engine off) (open circuit) the engine volts came up to 12 everywhere except at the starter... Bad connection near starter. Hope OP's problem is same, easy enough fix (when you know).
