i changed my alternator and my battery but my battery light is still on.i also changed my ignition lock cylinder because i couldn't get the power to turn off
time to have a mechanic do some hands-on testing!
A ignition is in two parts, where you put the key to turn it and a second part that is the ignition itself. Between the two parts there is a small flat pin or bar. This is where your problem is, the pin/bar is broken. You will have to replace the ignition to solve the problem. If the security light is blinking it will not start. The security system needs to be reset. You will have to have a fully charged battery to reset the system. With a full charged battery turn the ignition forward until the warning lights come on and leave the key in the on position for 15min. Turn key off and wait 10sec. then try and start.You may have to perform this procedure a couple of times, however, it is usually successful the first try. The reduced power light can be set by a low voltage/poor charge battery Hello,  
  
Put in new batteries and try again.  
  
If new batteries did not solve the problem, the next thing to check would be the battery terminal.  
  
If
 the battery terminal is rusty, the battery power won't contact and the 
calculator won't turn on. So, use a flat small screw drive to scratch 
the battery terminal so that there would be contact.  
  
If the above
 is not the problem, the next to check would be the wire connecting the 
battery terminal to the the calculator's main board. There is a wire 
between the battery terminal and the calculator board. When the battery 
is inserted, the power from the battery goes from the terminal to the 
board through this wire. There is a possibility that this wire is cut 
in-between or is loosing contact. In this case, you need to get a small 
screw driver and carefully disassemble the calculator in order to check 
the wire.  
  
If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.  
  
If non of the above helps, then it means the calculator is dead and needs a replacement.  
  
Regards. problem is a bad capacitor on the power board. caution if repairing yourself as capacitors in tv's hold a charge long after set is powered off and can be lethal. 
  
 when looking at your power board for a bad cap look at the top of the capacitors. a bad cap will have a noticable "bulging" on the top of it compared to others. be sure to note polarity of capacitor (will have a "-" on one side indicating negative. to fix on/off issue simply unsoldered bad capacitor and solder in a new one with same voltage and capacitance rating being sure the new capacitor is oriented the same as the old one was before it was removed. Here are a few things to try to help you diagnois your problem.  

1.Check for corrosion on battery terminals and the fuses.   

  

2.Fuses are good - Did you check the fuse on the top of the solenoid?   

  

3. Take a screwdriver and jump the solenoid wires to start the engine. If it starts, then your starter is good. (could be a bad solenoid - but lets check some wires first)  

 Your solenoid operates when you hit the start button.  

 Your start button won't work until you turn the on/off switch on.  

 Your on/off switch only has power when you turn the key on.  

4 Use a test light to test the following:  

 Right Handlebar switch house - Test to see if you have power to on/off switch - Turn your ignition key on & off to see the testlight come on - if light comes on that means your igntion switch is good. If no light, the problem is in the igntion switch. or the main fuse to the igntion switch is bad.  

  

 If the light came on then you have power to one side of the on /off switch - test the on /off switch by turning it on and off. When switched to on you should have power to the other side of the on/off switch which is sending power to the rest of the bike which includes your starter button.  

 Test your start button with the test light by putting the test light on the solenoid - Turn key on - turn on/off switch on - push start button and see if the test light lights up. If the test light lights up that means that your solenoid fuse may be bad. It is located right on the top of the solenoid. If the fuse is good then that means your solenoid is bad. Replace it with a new one.  

 If the Test light did not come on then your starter button is not making contact and needs fixed or replaced.  

  

So follow the power with the test light until through each component until you come to the faulty one.  

  

NOTE: If its a blown fuse, check your wiring. You'll have to find out why the fuse blew and fix it or your fuse will just blow again. Could be a short somewhere, installing a battery wrong will blow fuses. I have this problem too. I've tried many way too fix it but my phone still have this problem. timgoos,there seem to be a few threads about this issue. most people, at least those who bothered to respond back to this forum, seem to indicate that turning off the "lock screen controls" resolved the issue for them. my guess is that there's a bug somewhere in the app, and they haven't either figured it out, or looked at it. i'd suggest that you go to settings -> sonos -> lock screen controls and make sure it isn't green (on). it's inconvenient, if you're accustomed to using the lock screen like i am, but then again if it doesn't kill the battery, that's a plus.and if you'd be so kind as to come back and post here to let us know if it works for you, it might help the next person who may be in your shoes.thanks! Hello guys  
  
I had the same problem. My LCD ViewSonic VX 924 has been blinking   
  
For repar it i changed the following capacitors : 100uF/400v  
330uF/25v and 330uF/35v   
  
if that always flickers you can also change the two 470uF/25v capacitors

DO NOT TOUCH NOTHING D'OTHERS ANS DISCONNECT ELECTRICITY CABLE BEFORE PROCEEDING hi everyone, just to close this topic, i could get a proper power supply and in fact it was the problem..

thaks everyone for your time and help ! either it can be issue with blown fuse controlling the central locking or its issue with central locking control module.many a times these module gets wet,due to water getting collected there and after that such problem starts.clean the water and dry that area and recheck,if its working.
