help posable short

what car it is would go a long way... I do assume by the problem it has a rallye dash as this is common failing to it and by the other post yesterday stating you had three posts on the back of the fuel gauge. The rallye dash fuel gauge has the voltage limiter built inside of it. When the limiter goes bad it sends battery voltage to all gauges save the amp gauge. All the gauges peg and quickly burn up the insulation on the nichrome wire (that is what you're smelling). You will need to replace the gauges or have them rebuilt and eliminate the internal voltage limiter for an external. Try contacting redfish PM on here and he should be able to help you with repairing your guage(s). http://www.demonivr.com/Chrysler Rallye Gauges.html

I would disconnect the round plug in the back of the dash to try and preserve what maybe left of the guages. There is a bi-metal strip that the nichrome wire is wrapped around so killing the over volt issue now may preserve the bi-metal from being destroyed rendering the gauges un-rebuildable.
