'89 345 LE motorhome temperature gauge - see photos - hasn't been working and all of a sudden started working showing crazy numbers in the temperature window and then started smoking. There was a heavy electrical smell. It is located in the overhead area above the sun visors. We disconnected it. We tried to contact the maker Larson Electronic Mfg but they were sold and resold 4 different times and now the current owner doesn't deal with this gauge.
Are there any suggestions out there for replacement? Thank you.
