Is anyone familiar with the circuit for the Blue Sea PN8248 battery monitor. Mine (N331) suddenly stopped working – the charger is ok. The circuit shows that the monitor should be fused close to the battery but I can find no evidence for a fuse. Connecting a temporary supply got the monitor working. I have traced the circuit as far as connection 15 on the internal fuse/junction box but where if anywhere would the fuse be? Any ideas? Thanks Mike Can supply some images if that would help.
