Re: [time-nuts] HP Z3815A manual/info needed
Forgot to mention: if your Z3815A is like mine, then the GPS antenna cable is routed in a strange way. To bypass the large rear connector, the cable is soldered on the PCB where a short cable with connectors then brigs it to the Furuno GPS unit. There is a DC blocking capacitor so that the antenna is supplied by the main board and not by the GPS unit. Chack that connection.

Hi If the 3815 is similar to the other HP boxes, there's a GPS receiver card in it. Some are derivatives of the Motorola UT series, some come from other manufacturers. Swapping the cards between two boxes might speed up the troubleshooting process.
