Help! have a 1990 27 DA with twin 4.3lt ( for sale by the way) Anyway, hooked up batteries and started for first time this season. Both temp gauges were pegged even before I started second engine. I went back and checked all my negative grounds and they looked good. Even went and unhooked all batteries and gauges still stayed pegged. One interesting note, when I turn on running light switch it makes the oil gauge on one side jump. Then when I turn dimmer switch it actually will move oil gauge. I have to have a short somewhere, but I thought disconnecting power would at least reset gauges. Any ideas?

looks like missing or loose ground wire somewhere

I'd suspect ground, also.
When you say you checked all the grounds, were you referring to the gauges? I'd pull the gauge panel and check all the connections, make sure none are shorting or loose.

If one of the other guages lost their ground, would that affect just that guage or trickle down the line?
Ground doesn't have to be lost on gauge, could be loose ground wire on engine, battery, ground bus etc. In that case your gauges acting as "wire" and letting electric flow through gauge to feed something else. You wrote that light dimmer affect one of your gauges.
