[oletrucks] Heat Guage

["Billy Gibson" <bgibson@internetwork.net>]

I need help on my heat gauge, I have put in my third dash
unit and get a different response each time.
The sending unit I bought from Chevy Duty seems to be
working fine, 0 ohms when cold and an increase in ohms
when heated, there is voltage coming from the dash unit.
when engine is started gauge perks up to were it belongs
then in a few minutes it pegs out  to the hot side.
any and all suggestions are welcome.
Thanks in advance
