Like I said in my other comments, spray ALL electrical connections you can find, because as I found out, you fix one problem, another shows up. I think that's the problem with these little cars; there's no electrical grease, and with time etc, even though they're sealed, the heat, fumes and steam eventually builds up a resistance coating, causing problems (it's there, then later it's not).
