Trouble starting when damp/wet

[awf]

Hi there, I've had my GZ for a year now and has given me very few issues.

It is garaged over night and has no problem starting in the mornings but I park it outside at work and if it has been raining or even heavy mist during the day it is very likely to have starting issues that afternoon or evening. I live in sub-tropical Queensland, Australia so it is nothing to do with a cold winter.

Pressing the starter the engine cranks over but won't fire so I need to bump start it, I assume it is an electrical issue, water getting into the wiring or connections somewhere, can anyone help me with likely suspects or possible places to start pulling apart to waterproof/tape up/whatever may be necessary.

Thanks guys!

Andy
