Corinium Duo 2017. All worked just fine until I had HPC and SemiAir fitted. Afterward, the GasIt LPG gauge lost its perm 12v supply and the below problem manifested.
Problem
On occasion, the 12v circuit will switch off entirely; there is a noticeable click from the oven/sink area, and everything goes off but the fridge lights on Gas. I cannot see anything that has "tripped". Switching the EC480 back on, it does so for about a second then it trips out. I can see briefly (as you can with EC480 "off") the various levels and disturbingly I can see the vehicle battery range up and down from 0v to 16v! Disconnecting the vehicle battery at the ignition makes no difference other than at some point it settles and correctly reads 0v from the vehicle battery.
It will do this consistently for ages until I physically turn off the EC500, wait a few mins, then turn it back on again. Then it might all be good again for hours or days even, but at some point, it switches off and we go round in circles again.
I've tried the above with EHU connected and not connected and I've tried it with just the 12v on, no pump or lights and get the same issue.
Solution?
I wonder if you good folks have seen this before? I'm tempted to think it's the charger unit because I can't see what else might trip out and couple that with the odd vehicle battery behavior. Of course, it could be something to do with how the wiring was done for the HPC and air compressor but I'm at a loss to explain what or where the 12v "trip" is...
Your thoughts in helping me troubleshoot are welcomed - thank you...
