2002 Holiday Rambler Imperial dash short

[DrWil]

I replaced the coolant temp gauge and now all other gauges have stopped working. The dash lights work. The tach, oil pressure, trans temp, volt meter and fuel gauge all went off, i turn the dash lights on anf the trans temp gauge needle goes all the way to the right.

Looks like a short or a grounding issue.

I have the schematics and im looking for some troubleshooting help please!

Looks like a short or a grounding issue.

That would be the most likely thing that is common to all of those. I'm not sure exactly what you are looking for but it is pretty common for a dashboard to have a circuit board of sorts that numerous items are installed into and with a single ground connection. Once you have access to the back of the dash, look for something of that sort, locate the common side which will be the ground and use your ohm meter to measure between it and a good chassis ground. If it is not good, look for the place that the ground lead is connected.

I discovered the ignition switch is broken apart. Im having to replace it now.

Any guidance where to purchase the correct switch?

I replaced the ignition switch, there is still a short somewhere

A short, or a missing ground? Since it effects so much I still believe that a common ground is the most likely. If you use an ohm meter it isn't difficult to check for one.
