Starter Problems

2005 LT, new Odyssey battery.

I have been away for the last two weeks and came back to find my battery dead. Very unusual considering the battery is only a month or so old. Anyway, jumped the battery to my car, read 12 volts and got all the regular lights etc no problem. Pushed the starter and no joy. Tried the usual suspects, the sidestand, reverse knob, hitting the starter button several times, turning the kill switch on and off to no avail. When I do press the starter switch I hear a very faint click down where the starter is located. Incidentally when I use to turn on the ignition all the lights would come on and then I would have to press one of the buttons on the alarm fob in order to disengage the immobiliser. As far as I can remember when I pressed the button on the key fob the hands on the clocks would jump to full rotation. This jump does not appear to occur now. I have a spare alarm fob and it does the same for it also. How the hell can I get this beast started.

Re: Starter Problems

If you have replaced the battery you may have left one wire off of the positive terminal (there are several - don't remember how many). One of these feeds the starter relay (click but no start). Also the alarm has been known to go back to the immobilizer default with a dead battery. Or the alarm has just failed. In the "Files" section under "Technical" I have posted a procedure to bypass the alarm on the 05 and up bikes.


Hope it is just a forgotten wire. I get the sweep of the dials upon key on, but then I have had the immobilizer turned off since I bought the bike. This may be a clue that the alarm has failed.

Re: Starter Problems

I have done a couple of thousand miles since replacing the battery. I will check out your advice in the technical section.

Thanks

Re: Starter Problems

My first thought would be to fully charge the battery. Jumper cables often don't work as well as you might thingk. And if you start the car and try to jump it, I think that is considered a no-no on the forum. Not sure why, but I recall reading soemthing about it (jumping with/without motor).

As for the starup sequence, when I turn on my key I definitely get a full blown instrument check (all needles move, al lights flash) just when I turn the motorcycle on.

I will also offer the old adage about the alarm reetting to factory defaults. That setting imobilizes the system so you can't start it. When that occurs, if it doesn't register your key fobs, you need to use your security key to reestablish the link between key fob and alarm. Mine, thankfully, was reset by the dealer to disable that feature so the alram is only active when enabled by the rider.

Re: Starter Problems

One other thing there is a circuit in the starter relay that prevents it from engaging if the voltage is too low. This was done to preclude the "welding" of the relay contacts during weak battery start attempts. Follow the recommendation of a good full charge.
