    anyone else have a volt meter dance up and down when the plow has been used for a while? i have a 2005 sierra and my volt meter moves like crazy! i changed the battery out for a optima red cover battery but the meter still dances. i took the truck to a local shop and had the electrical checked out but they said all was good so, any suggestions?
