Check if your charging light on the dashboard comes on when you switch on ignition if not...on the alternator there will be a thick red and a thin blue wire check if the connections are tight and the blue wire is not broken off... if ok take a piece of wire,clean both ends and put end on the post where the blue wire is connected and end anywhere on the engine or the body of the alternator switch the ignition on and check if the light comes on... you have a faulty alternator if the light is not coming on the problem is on your wiring or your dashboard... if you have any questions contact me at 27822600976 my name is Solly.
Power comes from Battery. Sounds like A.) possibly you may have a loose connection. B.) If you mean the Alt is not charging the battery... well question. Did you disconnect the Negative wire to the battery? If you shorted (sparked) the Positive to ground you may have blown the diode in the Alt. or blew a fusible link on the Positive cable. Hope I helped
Check alternator for out put. Check fuses
Easy to see why
starters do not charge batteries
alternators do that
SOURCE: 95 jetta wont start
check your fuses under the hood and under the dash
check polarity of battery (if you unhooked booth leads)
is the battery any good?
you probly conected the leads to the starter incorectly (recheck them)
(the following asume your tur n key ignition system is functioning properly)
to test your tur n key system simply hook up a test light to the small lead running to the starter cylynoid "while the wire is disconected" and have a friend turn the ignition over. [dont furget to test the test light first lol]
or even got the wrong starter completly (usaly a store problem)
did you " bench test" the new/used starter befor installing it ?
iv goten brand new starters doa
is the ground strap hooked up ? is there corosian on the battery posts or any of the high amperage conections?
is the cylynoid on the starter or somewhere else under the hood?
cautiously try to bypass the cylynoid ie run a hot wire to the small lead on the cylynoid
(this can usaly be done by jumping from the main red wire on the starter to the hot lead of the cylynoid)
notes: when bypassing the ingnition system (jumping the cylynoid)
DO NOT have the ignition in the on postion and it is best to remove the lead from the cylynoid (incase of a short in the wire's some place)
if nothing remove the large red wire on the cylynoid and touch it directly to the starter lead itself (there will be a fair amount of spark when doing this its normal) but make shur you are conecting to the starter lead and not a gound point as this will cause exsesive sparking that isn't good
dose the starter tur n the engine over
back track untill you find the fault be it starter itself,cyclynoid,wiring,blown fuse,corosion,bad battery,
still cant find the problem take it to a shop!
hope i helped yah
Testimonial: "it was very helpful my friend came over it is the alarm system we diarmed it and it started right up thank you for your help "
SOURCE: 99 saturn SL sometimes will turn over, and
yes, it could have a dead spot on the commutator. Try hitting the starter with a hammer. If this works to get it turning, replace the starter. If you need instructions or have more questions, please let me know.
