Alpine wiring

Newby here looking for help diagnosing an intermittent electrical shut down.
While heading home from a winter away we travelled 1700 mile north problems. At 65 mph the vehicle lost power and all indicator lights came on on dash. As quick as this happened the power came back and lights went out. This happened one time and no problem getting home. I remember while doing research that the vansco 2820 had recalls due to this exact condition. So I’ve checked all connections in the engine bay scanned for codes (there were none) and pulled the gen slide out and visually checked those connections
Any and all positive information much appreciated

When I've had issues like that what I've done is Remove, Contact Spray, & Replace any and all connectors that run from the engine compartment to the dash. Inspecting too, looking for contact anomalies. In my '02 Diesel, there's a bunch of them. That wiping action of R&R connectors has done the trick for a couple of my dash gauges bouncing. There is also a big connector on the engine, and one on the tranni.

And then, there have been reports of a manufacturer who put a large multi-wire connector between the engine component boxes and the dash UNDER the RV. Where it's subjected to road water, salts, and other nasty stuff. Getting all rusty and groady. My memory may be faulty so please excuse me if it is, but I think I read that about the Alpine.

Someone with your model might have better advice.

I appreciate the guidance so far looking to replace the ignition switch and testing each connection
I’ll keep you posted on progress
Thanks

Next "suspect" if electrical goes out (including Allison shift pad) is the IGNITION SOLENOID. The ignition switch turns it on/off.


Use alligator clips and a digital voltmeter on the "out" side of the ignition solenoid. If voltage drops when ignition on, next place to check is the small 12 VDC positive signal wire from the ignition switch that closes the solenoid and powers the engine/transmission, etc.
