I have an old coachman genius 1994 and it has been connected to the mains as we have been restoring it... today the 12v system just stopped working, the lights etc that run on 240v still work fine but nothing in the 12v... the battery charging light and battery indicating light used to come on but not anymore... please help! Thank you
