Gauges stopped working on my 220SD

[MLB1311]

I have a 2008 Sea Ray 220 Sundeck and the Speedometer, trim on the center gauge, and digital led screen on the tachometer (not tach) all went out suddenly while boating last weekend. Otherwise boat ran great had no issues. Ive checked all the fuses visually and with a multimeter, none are bad. I pulled the dash panel and checked all the connections, none were loose. All the gauges are getting power. What else can I troubleshoot to correct the problem.

Try jiggling your ignition key/switch. Could be bad switch

Do you have power at the purple wire on the ignition switch?

Update: Jiggling ignition key/switch made no difference.

Can you find the “cannon” plug behind the dash?

when this happened to me, I disconnected it, added dielectric grease and it’s been good so far.

Yes, I have power to the purple wire on ignition.

I decided to try to reset gauges by disconnecting everything attached to the batteries and it worked! When I powered it back up everything came on and is function as it should.
Thanks for all the suggestions, your help is much appreciated!
