Fleetwood Revolution diesel 40ft Dash alarm comes on Gauges go out dash alarms; with water temp, oil, battery lights gauges light up all together, and then (speedometer, odometer, temp )guages ALL GO OUT ! But it runs fine, coolant is fine, oil is fine, batteries are fine.....can anyone help?

Unfortunately this is a well known issue and well documented.

Your bad cable may have prevented the battery from being charged up good. Put a battery charger on it, or replace it if over 4 years old.

So the problem is it starts and then dies? How many amps did the alternator show? Was it enough to run all power circuits and charge the battery as well? That could be a concern. It is possible you have a bad ignition switch, but first check the fuse for the gauges in the instrument panel fuse block-it may be labeled "gauges" or "meter". The fuse should get power with key on, and then power is sent to the gauges on the dash. Without a voltmeter to test for power coming out of the switch, it's kind of a guessing game. If power is not getting to the gauges, it may also not be going elsewhere out of the switch.

Any issue with a security or theft alarm light staying on? That would disable the engine from running. Post back with year, make, model, and engine size. Maybe I could look at a wiring diagram for further help.

check gauges sensor location upper of the oil filter black color take it out clean it well then try it if no change it and don't worry it's cheap

ALWAYS check the body grounds first. Ground to the dash gages could be faulty, dirty, or just not tight enough to make a good connection.

does your car turn over or start? check for lose ground/power

The beeping alarm would be for leaving the key in the ignition or the lights on. Maybe a gauge that had dropped to zero.
Let us know if it happens again and what the conditions are.

SOUNDS LIKE A RELAY.CHECK UNER DASH AND OUTSIDE UNDERHOOD.

there are 2 connections on the bulkhead/firewall. There is one on
each side.The connectors are brass and the insulators are
plastic with a rubber boot. unless these connections are clean you may get all sorts of malfunctions with switches,lights and electric
motors. Symptoms are similar to a failing battery, something to start with..

good luck

I read on another site that if the indicator on the dash is malfunctioning and there's a fault code in the system, the beeping is a secondary indication that there's a need for service. I've had my air bag light blinking for some time now. Yesterday my gauges went out, Oil Pressure, Gas Level, Temp Level, and the Battery Charging Meter, all went dead. After starting the vehicle, it beeps 5 sets of 5 beeps. Since the dash obviously has problems, (Including the Air Bag blinking thing not working), the beeps I now hear are what you are experiencing. However, if you still see the air bag light blinking, maybe your situation is a bit different than mine.
