My dim lights work fine when i click over to high beam they work for like 30 seconds then they go out. if i flip them back off and turn then on again back on dim they work fine and will stay on..i have an rpm gage also when it gets up so high it goes crazy... and also my radio when i turn it up to a little under half full volume it starts to fuzz out like its not getting enough power ....i checked the grounds going from the lights there all fine i cleaned the connections and also the power supply wires but it still does it..the engine is grounded to the frame properly also... any ideas where to start or what to do?
