Anyone else out there with S-Tec 30 and GPSS?
Any of you having issues with the internal fuse in the GPSS module?
Mine blew once during construction and was a real pain to ship back and have S-Tec (whatever their name is now) solder in a new one. I attributed that to using a power supply (even with a battery) to run my panel during build testing. It has since blown again and I am trying to figure out a way to not have to go through this PITA another time.
More importantly, what is causing this little critter to pop in the first place?
The rest of the panel works fine with no other avionics issues. I have gone back to my engine monitor to look for any recorded voltage spikes....the highest I have is 14.0 which should be within the normal operating range of the system (?). I have spike catching diodes on my relays and have a process for powering up and powering down stuff like this to prevent it from happening for other reasons.
Your thoughts please,
