Check the big white battery power connector to make sure the metal tabs are making a connection to the female connection when pluging in the battery to the ups. If the tabs are not aligned the battery is not making a connection to the ups and will not engage the relays in the unit. Again check the metal connections in the male connector to make sure the flat tab is aligned with the female plug when connecting the plugs together. I could not get my ups to power up and the reason was because when I connected the battery the tabs in the plugs were not making a connection and the ups was not getting the voltage from the battery that it needed to power up the relays. I checked everything in the ups and then I looked closer at the battery connector to make sure the ups was getting the power form the battery and it was not electricaly connected to the ups because of the large white connector tabs were not aligned to connect to each other.

It could be the wire from the alternator to the ECM. Or the ECM has shorted.

Car was rinning perfect. One day it would not start. there was nothing, no clicking ,bell and guages were working. Jump start was nothing. Installed a new battery there was nothing. Went bact back 2 hours...


It sounds like you have an issue with your PassLock security system. I had the same with my 2002 Impala. Key turns OK, but won't start, won't crank. Wait 20-30 minutes, and car starts normally. There is usually a clue from the Battery and Security lights.
The problem starting to happen once a month, and eventually 1-2 times a week.
There are several write-ups on this problem for several GM cars for 2000-2006(?). Search this website, and search the web.
The official solution is to replace the ignition switch. The best solution is to bypass the Pass Lock system. I went ahead and did a full bypass, which involves cutting wires and adding resistors to the ignition circuit. I have not had a problem since.

Its not hitting right in the motor , its running on 5 cylinders when its a 6


Missing on a cylinder is always an ignition system problem. Replace plugs, plug wires, coil/distributor unit. Make sure your plug wires are routed right. Make sure timing is right. This should fix your problem.

1997 Cutlass Supreme charging system problem


Check the bettery cables at the bettery and at the engine and stater, if they are corroded rusty or greasy, it will cause this problem. If there is corrosion at the battery replace the terminals with after stock from autozone. Also check the wires at the alternator to make sure they are also ok.

Hunter ceiling fan w/handheld remote. At times the fan will shut itself off and/or the light will go on by itself ( ie. no one has been near the wallswitch or remote)


1. check your bettery. put in a new battery. retry.

2. pull out the remote unit in the ceiling fan and check the wiring. be sure all wiring is securely wired together.

My 1992 Buick LeSabre custom won't start at all. So where can I find the Fuse Box for the Alternator?


an easier solution to this is to disconnect the negative and/or positive battery terminal with the car running, if your alternator is working it will keep the car running. To find the wire that goes to bettery can be a PITA, so I reccomend going to an auto parts store and getting some 8 or 6 guage length of battery grade wire and connect that directly to the alternator and the positive end of the battery. I'd do this because you may have a faulty wire that doesn't keep the battery charged and it's hard to trace the wire route through the rats nest of wires it runs along with.
