Help with damp electrics please.
Hi. 06 gt 2.0jts. Installed aftermarket stereo and works perfectly until it rains! When it rains it switches on and off usually straight away but at random.it's very annoying. It maintains its settings when going on and off It just looses power randomly. Have rechecked all wires 100 times and got a replacement ctsar003 and still happening. Can't duplicate the problem but it always happens when it's really raining hard. I presume I have damp in the electrics somewhere and have seen a product called wet protect which you spray all over your electrics and it displaces damp and water and protects against it. I can't find anywhere that sells it in the UK, could I get something like Holt damp start and spray that everywhere? I Mean to spray ecu, battery connections and fuse boards to see if I can got rid of the problem. I am not very technical so bear with me! I found a wire under the bonnet which was fastened to chasis. Presume this was ground/earth, checked this and cleaned it but cannot find any other earths/grounds to check. Basically is this spray ok to spray all over electrics? It's Deffo caused by rain/damp. Didn't have no rain for 2 weeks and not 1 problem then as soon as the rain starts its back. No other electric problems.
