Title: Ignition switch and dashboard dials problem
Post by: John Kellermeier on September 11, 2020, 06:40:03 PM

I have a 2008 Beaver Contessa.  We woke up this morning to find that the dashboard is partially lit up even though the key in the ignition is turned to off. In addition the dials are going on and then off repeatedly.  We've tried starting the engine and then turning it off, turning the key to the ACC position and back but nothing stops it.

Anybody have such a problem before or have advice?

Thanks!

I have had similar issues that were the monitor bar that displays the ignition warning lights and the LCD.
We were able to shut it down and restart going very slowly in the start up sequence. 

If that doesn't work you might turn off the coach power and or the chassis batteries and wait a few minutes to restart.

Could be the ignition itself overheated and shorting across inside, or at the ignition solenoid in the 12v electric bay (streetside forwardmost) the solenoid’s high current contact’s are not completely separating when small post ignition power is removed.  Built up carbon from repeated arcing can cause contact points to still barely connect and pass a small amount of inconsistent current.

Others more in the know might think the solenoid’s diode was bad, allowing feedback?  Probably not.

Both the GM ignition in the dash and the solenoid are known to be problematic.
