I have had that problem with a totally different cause.
I used to store spare change in the ashtray by the Cig lighter. I saw my gauges go bezerk some times and the every now and then the fuse(s) will blow out. I thought I had major electrical problem but then by chance/luck I started to clean out the ash tray and then I noticed that a few coins had gone under the removable tray. I took out the whole thing and found a quarter stuck next to the Cig lighters exposed wire contacts. I took out all the coins from under the tray and I do not store anything metallic in there and since then I have had no problems at all.
Please check to see if you have a similar issue too.
Cheers!
Bob
