I have a 91 Previa with some electrical woes. It is an intermittent problem.
The gauges, temp, gas and speedometer don't work. Along with the idiot lights and the overdrive. The van starts and runs good. The first thing I did was check the gauge fuse it was good but I changed it anyway. I have been chasing down the problem with the electrical wiring book but that is not the clearest thing to follow. I just looked through the forums and didn't see any similar problem but I did see a very useful "how to remove the dash"
Does anyone have any helpful ideas?

Thanks, Rick
