thing that works is the horn.? My Car starts first time and sounds good but, after 20 minutes, the Engine dies, ignition lights go dead, as do dash lights, headlights and everything else, except horn which works perfectly. I thought it was a faulty battery so I fitted a new one. The terminal connections are tight, but problem unresolved. After about half hour, everything comes back to life on its own and the car can be started. It runs perfect for rest of day. This is a daily occurance and is driving me mad.
