Feroza F300 Temparature Guage

[K1W1]

I recently had my temperature sensor replaced by an auto electrician and in his attempts to get an accurate reading from it he wound the gauge forward with the result that my truck often records temperatures in the H zone when in fact its not.

I've had the dash board out but haven't figured out how to re adjust the gauge & the sparky wants money to make the adjustment.

Does any one know how to do the adjustment?

Cheers

Chris
