240dl 1986 temperture gauge reads erratically

I know a jumper can be installed to replace the circuit board that has gone bad but I don't know how to do it or where it is. Can you help me?

I can't tell you exactly where to jump the two contacts, I'm sure someone will chime in with the exact location. In the meantime though, you can try a search of the forums using the part name as a query, the part in question is the Temperature Compensation Board.

More then likely this is your issue.

Clare, welcome to Matthew's Volvo Site.

Go with FCPGroton's advice and buy the bypass board from IPD.
