Is your right three gauges the ones that are going wacky?
Thank you for all answers! This site is really helping me a lot over time.
Somehow I don't think it the cluster itself. All gauges, including the compass and the computer and the light-level, are whacky. The whole cluster restarts itself, except for the speedometer and the rpm. And it is somehow related to the temperature for sure.
I'll think my first option is to check out the ground as suggested. The floor is not wet, but there is certain dampness in the climate with snow and fog. This may very well be the reason, but still I wonder over the intermittent behavior related to engine temperature.
Is there any chance that a clogged cooling fluid sensor can trigger this behavior? There was a post on crazy gauges, where the guy claimed that he found oil in the cooling fluid.
Here in Sweden the Bonneville is an extremely rare car. Not many repair shops are willing to address electrical problems, and model specific spare parts are hard to get, and quite expensive. So if I can't fix it myself with a cheap spare part, I'll settle with disconnecting the dinger or installing a switch on the fuse that controls the cluster.
