Lighting Issue!!

here it goes I thought my alternator was to blame but My battery light doesnt come on whats going on is I can go out start my car and have bright lights then after its running for a lil bit my lights start to dim and my car starts to bog down and it barely wants to run give it gas it pops and ya after a lil bit my stereo quits playin its on but nothing IM at a LOss but ya my battery light never comes on I can then turn my car off turn the lights back on and IM back to bright any ideas what this could be.?? loose ground maybe ?. Thanx for the help

A connection problem for sure, possibly a ground but it can just as well be on the hot side, possibly the main head light fuse, or the head light switch or the connections in between.
If it is on both the high and low beam and on both sides, I would guess something before the high/low beam switch in the combination light switch, as everything after that is separate circuits.:dozing: 94

delete!!

found out what it was even though my battery light didnt come on it was my alternator Its all good now
