Let me start by saying ARRRRRRRRRRRRGGGGGGGGGGGHHHHHHHHHHH!!!!!!!!!!
Ok, now that I got that out. I bought a new battery for my XB12R off www.batteryweb.com from their Buell page. They had a few different models listed for my bike. I settled on the YTX14-BS, a nice sealed no maint. battery. Well I get a battery in the mail, right form factor, look at the model number, and it sounds right although I didn't go back and look.
So anyway, I plop the battery into position and hook up the cables and WHOA the cooling fan comes on full boar. I quickly pull off the cable and stand there a little surprised, then look at the polarity markings on the battery and notice they are opposite from what they are supposed to be.
I hooked the battery cables up to the right poles and turn the key and NOTHING..... no lights, dash, nothing.
I hope maybe its the battery, so I grab the old one and hook it up, still nothing, oh no, oh no....
So I fear that I may have fried something in my electronics. I checked the model number on the battery I got compared to the one listed on their site and sure enough there is one letter difference which apparently must mean opposite poles.
I left a message at the place that kindly sent me the wrong battery, and perhaps caused me much grief and suffering, but I'm hoping some of the brilliant minds here might be able to shed light on what exactly might be the state of my Buell. Your help is GREATLY appreciated.

Check your fuses first and foremost. Your 30 amp fuse might have blown. Otherwise you could have fried a number of things. At best is a relay, worst your ECM among other things.

H-D/BUELL batterys are "NEGATIVE" to GROUND BATTERYs ... |

Your fan is wired 'live' so it runs on when the ignition is switched off, if the motor is still hot enough for the fan switch to make contact. That is possibly why your fan ran, but probably backwards.
I'd say at worse you've done nothing more than blown the 30amp fuse.

you should send it back and get a battery from harley. they are not all that much more money. i'm changing mine today. i'll get one from from h.d. and bite the bullet. the battery is tough enough to change as it is. i would check all fusses and wires first. then start checking wires and relays. if still nothing get the ecm checked. good luck bud. hope it is an easy fix fro ya. |

Buy an after market BATTERY and save $$$.$$
MONEY$$$.$$ to put up the "STRESS & BUELLschite" ...
Buy a H-D/BUELL BATTERY and you can go for a "RIDE" sooner |

Wasn't buying an aftermarket battery to get something cheap, but to get something good. They sent the wrong part and I didn't double check it, their bad, combined with my bad 
I'll check some of those options this morning and see what I can find. I figure worst case scenario, stock ecm's aren't hard to come by with all the muffler upgrades around here and there are only three relays, so even if I really did do a number it can't be that bad (fingers crossed). |

I notice they have diodes in the fuse block as well, not sure if one of those could be toasted as well. Easy to check if you have a "diode checker" on your Digital Volt Meter, a littler harder otherwise. |

From the wiring diagram, the components that would see the reverse polarity would be the voltage regulator, the instrument cluster and the ecm "keep alive" terminal, and apparently the fan through the ecm. I don't think anyone's done it before. If your fan ran then you should have no blown fuses or diodes. I would be inclined to hook up another battery and keep an eye out for smoke. If no smoke then check the battery fuse, ecm fuse and key switch fuse.If any fuses are blown, don't replace them and try again, get the fault fixed. If they are OK I would turn on the ignition and go from there. If the motor starts I would check that the battery is charging. I don't know if the voltage regulator would survive reverse polarity or not. It would be best to check it electrically by the manual, or if you can't wait, at least disconnect it until you can. Also disconnect it from the stator to be safe. |

Well, one blown fuse for the instrument cluster which when I replaced the needles ticked over and back, all other fuses checked out fine including the 30A fuse, but still get absolutely nothing when I turn the key to the ignition on position.
So it would seem at this point that the ECM is probably affected after all. I didn't think about the voltage regulator, so I'm glad you mentioned that.
Thanks for the suggestions everyone. |
