Replying to: overtorqued (Jan 04, 2007 2:25 pm) You have a break in one of the wires. More than likely at the break lights. Replies to this message: e7engineer (Aug 26, 2007 6:57 am) e7engineer (Mar 16, 2008 9:29 am)

2000 metro.4 cyl.i have new batt. new alt.the starter is real slow when trying to turn over engine.am getting over 14 volts at batt. , lights are bright. where is voltage regulator in this car? any diagnosing tips? happy new year.
#5 of 10 geo/suzuki voltage regulator by whaler2 Jan 01, 2008 (8:44 am)
I need to find where the voltage regulator is on a 2000 chev metro. Is it on the alternator? any ideas on diagnosing charging output? happy newyear.

Replying to: e7engineer (Aug 26, 2007 6:57 am) Had the same problem, replaced alt. Voltage stays at 13.8 with headlights and A/C on. Voltage regulator should be inside the alt.

battery was checked by battery shop and is okay, however the wife did leave the lights on for several hours before. charged the battery back up;drove 11 miles to work...cold weather but only after 8 hrs it didn't start...dead...alternator appears to be okay.. what's the problem? Also the engine compartment has some rattle coming from the drivers side? Replies to this message: zenden (Jan 03, 2009 5:36 pm)

Replying to: blueknight2 (Dec 30, 2008 2:40 pm) I would say that it has bad diodes in the alternator. this is most likely the reason that you had to replace the bat in the first place. If the diodes are bad in the alternator the voltage drops, it must produce 13.7 volts to charge that bat properly. Because the diodes are bad and the bat is new, you will not often see any trouble with the system, only when you discharge the bat to far for it to recover with that week alt. To prove that you have this problem with bad diodes get a dc volt meter start the car and turn everything on! create a full load on the system! then hook up your volt meter to the bat if it reads less then 13.7 volts then your alternator is BAD! As long as you never drain that bat down below 30 percent charged this monster will never leave you broak down; but once that bat becomes 2 or 3 years old the alternator will not be stronge enough to charge it up enough to keep you going. Your alt has 6 Diodes, they burn out for 2 reasons! (1) age!, or (2) giving or getting a hot shot! An alternator produces (AC) alternate currant; a bat will only take a charge from (DC) direct currant. The diodes convert AC to DC; they are delicate, and are like a one way valve, making the elect. flow one way only. When 2 car are connected together by jumper cables; one is running and the other one starts the 2 DC come together and blow out the delicate diodes; then the Volts drop below the needed 13.7 that it takes to properly charge a 12 Volt bat. in any car.  I hope that this helps you!
#10 of 10 car wont start 97 geo 1.3l by bogeyplyr Jan 17, 2009 (1:05 pm)
i got voltage to ignition coil but not sure how much hardly nothing at spark plugs tried two sets of wires different distr. different rotor, diff. cap different engine. im assuming crank shaft sensor wiring problem or pcm problem any help please!! How do i check voltage to cps and how do i check pcm to se if it is working properly.
