Nope, wrong again, you need to start with a fresh battery and work backwards, it may be a bad switch or in the fuel system, ya got to think before you post so not to give mis information like I have a few times, but I am right more than I am wrong, it comes from years of wrenching, that is all I do and I do it as good as I can with very few complaints and repeat customers
Did you even read the OP's post? He said he removed the switch and cleaned it and even removed and changed it with another one, still the same issue. What does a fuel issue have to do with lack of or no electrical power?
