I have a 1980 Sundowner and need to replace the voltage regulator and over voltage relay. The part number on the voltage regulator is B-00349-1; it is a Lamar. Does anyone know the replacement part number or know where to go to find it. I will also need the over voltage relay as well. Thanking you in advance.

You didn’t specify your SN, but being a 1980 I assume that you have the 24V system. The regulator should be PN B00306-2 and the OV Relay should be PN B00344-1.
I could not find your name in the BAC website. If you are a member, or if you join, you can type in “voltage regulator” in the upper right search box. You will find quite a bit of information on the subject, as well as references to parts sources. I personally recommend against buying more of, or working on, the Lamar parts. I have found them to be highly unreliable, especially at the price. Try Hazotronics instead. They may not be cheap, but they will last almost indefinitely once properly installed. They typically also provide additional diagnostic capability and circuit protection, depending on model.
