okay i heres the deal. when i turn on my dome light using the headlight switch my radio goes nuts. it will shut off and then come back on with all the presets stations gone and sometimes the clock will not be lite up. i haven't gotten a chance to diag the problem yet but i think that it might be a ground. has anyone ever had this happen to them also? if so what was the problem and how did you fix it? any advise would be greatly appreicated.
