dash charging warning ligth fails to come on when ignition switch is on.

92 honda accord lx auto f22a1

issue. my dash charging indicator ligth fails to come on while ignition switch is on but engine is off. all other ligths do their job and come on when the switch is on then disapear when i turn the engine over. this ligth used to come on and now im wondering why it stoped. i just put in a new working alternator in the car because my last alternator failed ( voltage regulator ) and this ligth failed to show up when i had the bad alternator in so i figured it will come on again as soon as i put in my new working one. i know it works because the car has full power now and i took it to advanced auto to get it tested before installing it.

any ideas will help thanks in advance

Is the bulb good?

[pike0825]

i havent checked it. how do i check it and where is it?

[Chris2388]

The bulb is in the gauge cluster. You need to remove the cluster to check it.

the bulb is probably bad since it doesn't come on during the ''bulb check'' part of starting the car. later.

ok i will check the bulb. so its behind the glass and behind the gauges with the needles. seems fairly easy. am i rigth?

[Chris2388]

You will need to remove the plastic as if you were going to install a new radio then there are 4 bolts holding the cluster in undo those and undo the 3 clips and then pull the cluster out its a lil painstaking but just take your time. once out just go thru and look for bulbs that look black and replace.

thanks i will check the bulb A.S.A.P. lets just say i check the bulb and they all seem fine( even replace the bulb just to make sure? ) and the ligth still fails to come on. what can i conclude in that situtation? i just ask this because it migth be a hastle to get to this bulb, should i check for anything else before checking the bulb? and are these bulbs some that i can buy at any local auto store?

[Chris2388]

For this question I would wait for someone else to answer. But all i can say is check your fuses and make sure all your wires to your alternator are nice and snug and have no corrision.

[pike0825]

are these bulbs some that i can buy at any local auto store? and also what fuses in particular should i check because ived checked a couple of them that i though were related to the problem. or should i just check all of them?( both fuse boxes )

If you want check the complete circuit, do as follows:

- Turn the ignition off.

- Check fuse #2 dash fuse box.
- Bad, Replace. Turn ignition switch on. Does it light up?
- YES. Good to go.
- NO, Go to next step below.

- Good, Disconnect the 4 pin connector at the alternator.

- Turn the ignition switch on.

- Check for voltage on the BLK/YEL wire on the 4 pin connector.

The connector looks like this:



- Is there battery voltage?
- NO, Repair the open in the BLK/YEL wire.*

- YES, ground the WHT/BLU wire on the 4 pin connector.

- Does the light come on now?
- NO, check for a blown bulb. If the bulb is okay, repair the open in the WHT/BLU wire. **
- YES, replace the voltage regulator. It is in the Alternator. Or just replace the alternator.

This is why I always check the bulb first. You end up checking it anyways

* goes to the dash fuse box and fuse #2 15A

** goes to the gauge cluster charging light.
