Instrument cluster accuracy off after winterization

[Paul Perryman]

After winterization all gauge cluster readings seem off. Temp +20 deg from typical (but steady), Fuel +1/4 tank from actual, volts low, psi high. What do I check that could impact the reading of all inputs?

Check all the electrical connections to the module. Corrosion or loose connections can cause high resistance and give you overall high readings.
