Q: repeat wrote now loud squealing on startup when engine warms up squealing goes away. squealing only occurs simultaneously with alternator gauge needle bottoming out in charge position alternating with normal position in which case squeal disappears-i.e. as long as needle swings back to midrange position squeal disappears only to reappear when bottoming to charge position. squeal and bottoming of needle go away completely when motor warms up. it sounds very much like something somewhere is shorting placing a heavy load on the alternator and making it drag really hard on the belt. the deflection you mention doesnt sound abnormal but might be just enough to let the belt slip a little and make lots of noise when the alternator is under full load. its also possible the voltage regulator is failing putting full field current on which puts the alternator on full output which squeals the belt etc. etc.. thats probably more likely than a full-out short on the alternator output which is of course also the battery positive. it could be the alternator itself shorting. very worn brushes or an intermittent diode could be the cause. this isnt very likely. -- liberals used to be the ones who argued that sending u.s. troops abroad was a small price to pay to stop genocide; now they argue that genocide is a small price to pay to bring u.s. troops home. -- jonah goldberg .

friend has a 88 dakota v6 auto 165k 4x4 -- nice truck. recently started setting code 13 only. today we filled with antifreeze non-related replaced air cleaner and cleaned housing and tubes added 1.5 quarts of atf non-related cleaned throttle body inside and out with seafoam checked wires and hoses for cracked replaced air breather and hose replaced pcv valve charged a/c - non-related adjusted ac and alt belts non-related put seafoam in gas treated intake with seafoam cleared codes this truck runs 100% better starts better and idle speed went up about 500 rpm at idle se we adjusted it to spec. it runs great ac works and doesnt miss etc. ran about 50 minutes on road and idle and didnt set codes. then it set code 13 again and comes one almost instantly when cleared. im thinking map sensor - but the one listed has a picture with three wires going into it and a hose and the one on this truck doesnt have a hose tube on it - right on the side of throttle body other suggestions are pcm anyone have any help and great ideas on this thank you .
