94 k75s reinstalled battery after 3 months no workie

[ludwig]

I'm thinking this is probably something simple, but my newbie status has me ignorant of the problem...

Parked the bike for a winter's sleep about 3 months ago in a non heated garage so I did my due diligence and pulled the battery (Odyssey PC680 about 1 year old)) to prevent slow drainage.
All systems were fine, bike running perfectly before parking and the battery was fine. I trickle charged the battery up to max anyway after I pulled it so it would be stored with a full dose of charge. Today, before reinstalling the battery, I reconnected it to my trickle charger just to be sure, and it went to "storage" mode after a few moments.
After re-installing--
No ignition lights
No lights
No sounds, no clicking or whirring
Clock is on 000, but goes blank with key on
Aftermarket headlights work with separate switch

Cycled the kill switch many times.
Removed and re-installed battery twice.
Pulled and inspected and reinstalled all fuses on left side fuse box.
Unplugged and replugged in ecu over battery.

Still same symptoms as above.

Hit me, friends.

I think you have a bad charger and a dead battery.

Have the battery load tested.

Check across the terminals with a voltmeter. It should be around 14v. If not then it's a dead duck.

Almost sounds to me like you missed connecting a wire. Other than that I agree with the others that something is amiss with the battery or charger.
Have you tried another charger?
Charging voltage should be in the 14V range. A static voltage reading should be closer to 13 and not much more.

[ludwig]

Leads across the battery read 12.84. Seems at least enough to bring the cluster up to at least dim illumination or get some kind of sound, but except for the add on lights there is nothing. Just the clock and again, it goes off when key turned.
I agree that it seems like something is not connected but the harness was right where I left it and all possible wires are in place at the battery.
I ran the probes across all the fuses in the left fuse box and they all have continuity.

Follow the ground wire from the battery to the engine, probably at the starter mounting bolts, check that the connection is clean and tight.

greetings ludwig...

so... is your clock showing 000 or is it showing 0000...

On the road again...BINGO!!
Thanks Scott and all the replies.  :clap:
Looking forward to hopefully meeting you guys at a rally in person one day!

Hey, what was the problem???  What did you find???  Was it the battery or the ground???

[ludwig]

Oops. It was loose ground connection.  :2thumbup:

Yup, my experience is that most electrical problems are related to loose or corroded ground connections.  The first thing we did when faced with a starter, charging, or power panel problem was go through cleaning and polishing all the main ground connections, especially on the batteries and the engine block.  About 2/3 of the time that fixed the problem, especially when commissioning in the spring. 

I never got into the chemistry of electrolysis, but it seemed the closer you got to the negative terminal on the battery, the worse the corrosion would be.

I hope you cleaned everything nice and shiny and put a little Vaseline on it.
