So the end of last season before i parked my 89 notch 5.0, 5 speed, I was having an intermittent problem. When i was driving at night my volts would drop sometimes and my lights would go dim.. and id hit a bump or hit the gas and volts would come back and lights would be bright. So anyway I parked it, knowing i would have to deal with it in the spring. Well its SPRING! So I jump the car... and wiggle some wires... its not charging.. eff it.. i go get a new altenator... hook it up...still not charging... ( now mind you I had 2 autozones check my OLD alt and said it was bad.) After the new alt didnt work I had a 3rd place check my old alt and said it was good.. HMMMM ANYWAY.. So i put my old alt back in.. and im back at square one. I wiggle my battery and some wires and boom the volts are back up. so I quickly drive the car from storage to my house and park it. its a half hour drive and it was at night.. lights were bright... volts were high. this was 2 weeks ago. So i put the car on the road all happy about driving to a local car show today and i hop in.. start it up and volts are in the red... i spent hours wiggle wires and strippin battery cables and puttin on new terminals.. tried a diff battery... i took out the volt meter and measured batt to chassis, batt to motor batt to every ground i could find... batt to alt... alt was puttin out 12.6v i spent hours chasin wires cleaning connections..checking with a volt meter.. im ready to pull my hair out... should i try a new alt again ??? i dont get why it would come on and off like a switch... i would swear its a bad wire or ground.. but it starts up fine just the battery wont charge... the alt says its putting out the volts... but im also no electrician... what can i check ?? it was intermittent before 2 weeks ago but today i couldnt get the volts to come back at all.... any ideas would be much appriciated... this is my daily driver now.. so i need it solved quick!
