    thank you Moe,
    I will try that.
    Another question if I may ask.

    my car also has a (luke warm) idle problem.
    It is fine during regular operation and on next day cold start, but if I leave it for an hour or so, (worse in winter months). It bogs as if it is going to stall giving it gas does not help, I usually pull over for a few min, it almost stalls a couple times then seems to be fine again.
    very strange.

    Do you thimk this could be a different issue or could it be related to the same problem?

    Thank you


    Tom

You may have a faulty alternator or and internal part in the alternator, replace it with a dealer part and that may solve the problem, it must be a dealer part..

    sorry for being late to respond..
    but your problem maybe common and none related but it maybe possible that it is related to the electrical problem(due to the high and low voltage) which may have damaged a circuit..... but two thing can cause the problem which are the Thermostat and the Coolant temperature sensor(s)
    let me how this may help......

2003 civic stalls at stop


If a Honda is not producing enough amps it could cause it to stall but the battery should die if its the alternator. Sounds like the coil or distibutor.

2007 civic si battery drain


Seen this "mystery drain" many times. Check spark at the battery to see how big the drain is. For this simple test, blow away any (explosive) battery charging fumes. Leave one terminal on and gently touch the other to its post in fairly dark surroundings. Then try it again with the wires taken off the alternator. Your spark is now probably much less. Usually bad diodes leaking electricity backwards through the alternator cause this drain. Replace the alternator or the diode pack inside it. Some mechanics recommend actually measuring the drain.... hahaha. OK whatever.

My 98 civic when driving it shuts off loses all power...turn key off n turn on again like reseting it starts up why is this?


It sounds like you have a major electrical issue or bad (shorting) battery. When you say it loses all power, you mean radio, lights, horn etc? Clean Battery terminals & look for ground wires that need to be cleaned & reattached. Check the black ground cable that goes to engine block. The more I type the more I think its a bad ground somewhere or the battery is shorting out inside the case. Good luck and I hope this helps you.

  1. Note the radio security code and the radio presets.
  2. Disconnect the negative battery cable, then the positive.
  3. Remove the power steering pump.
  4. Detach the wiring from the alternator.
  5. Loosen the through bolt, then loosen the adjustment locknut. Then loosen the adjusting bolt.
  6. Remove the alternator belt.
  7. Remove all mounting and adjusting bolts and then remove the alternator unit.
To install:
  1. Installation is the reverse of removal.
  2. Adjust the alternator belt tension.
  3. Enter the anti-theft code for the radio.

Hope helps (remember rated this).

2005 honda civic ex automatic stalled at 40 mph


Check the main fuses under the hood. There are several large ones there. A loose connection on one of them could have caused the sudden, complete electrical failure you described. If it is a loose connection, it would certainly explain why it "came back to life" by itself.

Also, might you possibly have any sort of aftermarket security system that has an immobilizer feature on it? While I wouldn't expect this to disable the entire car including the radio, if it were incorrectly installed I suppose it could.

I hope this help. Good luck!

The window of my Honda civic 2000 SI had stop to run. It is an electrical system. First I was thinking that it was the motor and the regulator but I just bought a new regulator and it still not work. What...


test with a test light at the switch for power if power is present the switch may very well be faulty if no power exists then ck the fuses if all are good the issue most likely resides within the rubber boot between the doorjamb remove it and check for power starts and ends and repair as necessary with a wire connector or a new length of wire

Car is losing power and speedometer not working


The alternator is dying...
It is not charging your battery. Don't use your headlights (big power drain) until you have the electrical checked.
AutoZone will analyze (free) w/o removing alternator (IN-CAR test)

Hope this helps, soon!

Honda civic hatchback si it has power till turns the key


It sounds like you have a loose connection at the battery, the door chime and ecm lights don't require much power. As soon as you turn on the key, more power is required, with a bad connection the power from the battery, will drop off. My guess either bad connection at the battery or a battery with a dead cell. Hope this helps.
