No Gauges Working

[LamontD]

I have an 2003 Sunscape which I put in the lake in early June. Everything was working at that time. Finally got out to use again today and started right up. However none of the gauges were working. Put my hand under the dash and wiggled around some wires and nothing. Took it out for a spin anyway and kept wiggling the wires and eventually everything came on. After about 30 minutes the depth gauge started beeping and showing "bait" then all of the gauges went off again. Disconnected all of the connectors and the contacts look clean. Plugged everything back in and still blank. Any words of wisdom would be appreciated.

Welcome, I get that occasionally on my boat too ... usually hitting a double up fixes it for me. Good luck.

( I would check the grounding strip.)

Check connections by the battery. That is where the power distribution splits in two seperate feeders, one going to the engine room and the other feeding the helm area. The dash MMDC puts out the "batt" warning if it see's less than 10.5 volts and since the engine is still running fine, that tells me the low voltage is isolated to the feeder that supplies power to the helm area. Check to see if you also loose power to your accessories when the dash power is lost. This can help you isolate your open connection.

My 2000 Sunsetter had no working gauges.

I bought a new Computer plugged it in--same-- no working gauges.

Took the Gauges to Bakes and they bench tested all 3 in about 5 minutes!

The Tach was bad. (it did not work last year)

I had Bakes copy the wiring diagram for the computer input plug.

Testing the contacts showed only 0.8 volts at the ignition part of the plug.

Tracing this wire to the dash and piercing the wire showed 12.5 volts.

I untaped the wiring harness and found two 2 amp buss fuses buried in the harness!!!@#$

The 0.8 volt wire was a glass fuse with both metal ends un glued (maybe from wire strain) and the unblown fuse filiment tickling the connection.

Replaced the 2 amp fuse, put my old computer back in, bought a new tach, SUCCESS!!!

I'm not impressed with inacessable or poorly located fuses--shape up Malibu--these are the stories that get repeated most.

I have the same boat. I'd love to see a pic. of exactly where those fuses are buried.

I have a 2000 Escape with a similar problem that I have not been able to fix yet. I'd love to know where those buried fuses are too!

I was out at the boat today. Again started right up, no gauges working. All accessory switches work, radio works, no circuits blown. Looked under the dash and jiggled things around again and heard a beep and the gauges popped on for a few seconds then off. Nothing looks loose. Unplugged the plugs and plugged them back in and still nothing. The ground bar looks good. Anybody with a wiring diagram?

I am "in the same boat" LamontD!! Wish I could help but I have the same exact problem but just one step behind you...I don't know what the ground bar looks like....
