temp gauge

[clint]

cruising at 3800rpm..engine temp at 175..suddenly needle drops to 0 and back to 175 back and forth several times...switched engine off and on again and this didnt happen again...faulty connections in the sender unit?? replace gauge?

If it drops all the way to zero then immediately back to 175 it's definately a bad connection. Could be at the gauge or at the sender itself.
