It works fine when engine is off, seems to be ok when van is ticking over, if I start driving i get the red light flashing 3 times and it cuts off. Any ideas?? Voltage is 13.7 at leisure battery !!
It does it when left overnight as well, I have put in thicker power feed and re done the earth hoping it was something as simple, it would seem not.
I would check the voltage at the propex and if you can check inside look for dull / corroded connections .. it might have got a bit damp. Its easy to get 13.6 volts at the battery, harder to get the same at the load end of the wiring.
Actually sounds like voltage is too high. ( not sure how) Measure voltage and speak to Propex. They are very helpful
Ok. The people at Propex say a voltage spike or dip for a millisecond is enough. The instructions say 3 flashes of LED is voltage to low, 6 flashes voltage to high. I am certain that the unit thinks the voltage is too high even though it isnt and is doing 3 flashes. I have dropped the solar panel to 13.7v and it no longer comes up with the fault overnight. If I turn the fridge onto 12v it doesn't come up with the fault when you are running the engine !!!
I was going to suggest using the fridge on 12v to draw the voltage down and see what occurred Not sorted but at least you know what's happening . What you need is good old fashioned, none-computerised model ... Sent from my SM-A320FL using Tapatalk
