WOW! Somebody doesnt have much to do...lol..Well the dealer put the bike on the computer that said it was the EHC causing problems....Dont get it wrong, I'ma Big Dog Fan! but the EHC seems to be a little "Problematic"...Come on we all know, Big Dog could have improved the circuitry..."Hence" Wire Plus....Lets not be "blinded by the light":cheers:
Problematic? Your ECH can certainly be bad but not sure what the definition of problematic is. 1%? 5%? of the dogs on the road have bad EHCs??? Again I am not an expert but I would think that albeit a pain in the ass for some the percentage of legitimate bad EHCs is fairly low. I bought my 08 left over 2010 of this year and it runs great! Just say'n. :D

MV here's to a new year and quick fix to get your dog back on the road! Hopefully you'll get one of those new fancy BDM replacements and let everyone know how it goes.

My EHC was acting up and the bike would just die and maybe restart but then it got worse and wouldn't even turn on.

THAT DAM EHC!

You know what the problem was.....LOOSE WIRE CRIMPS ON THE WIRES AT THE BATTERY. Thanks John.

I hope everyone gets there bikes fixed, I have about 30000 miles, do most of my own work, and love my dog. I figure it's as beautiful as any women, I give it less attention and get more from it, cost me less then any women I have been with PLUS in most cases I get something for my money - shiny piece of metal or something to install instead of having to think about my feeling or what someone thinks I did wrong, even if I didn't do anything, does not talk back and when it does (back fire) I like it. I get to wash it and touch it anywhere I want, OK now I guess I am getting carried away - I Love MY Bigdog, most good things in live you have to work at and I would rather work on the DOG. Is this the right tread OH WELL, OH on second ECM first replaced under warranty and no other problems to date.
you need to get laid!

The local stealer here had Ironhorse, and Swift. They now have Appolo, Bourget and Brass B.

I was ther on a sat and two peeps brought in there bikes that were f'd up

1. Ironhorse (pulled the seat and the ground bolt on the bat was ready to fall out

2. Big Dog (owner had installed LED's with the wire crimps bent upward:loony: and the seat had broken the wire.

Two easy fixes that the owner could have done. But paid the $65 per hour plus travel time just because they didn't check it out.

Thanks PurpleDog for tracking my Dog issues, but at the end of the day, I need a 30K dollar bike to perform and not be in the shop...No disrespect...

Did you really give 30K for that bike. I haven't seen a 30K dog in awhile. They're selling Bulldogs in OKC right now for 28K and those are 2010's.

Good luck on getting it fixed. Mines still under warrenty also so I understand running it to the dealer at the first sign of trouble. I also want to know the how and why something broke so maybe I fix it myself when it's out of warrenty. There's a lot of help on this forum. Just have patience and let everyone know what mods you've done to the bike and what the problem is. You can bet it's all happened here to someone before.

Also buy yourself a service manual for that bike. It won't be under warrenty forever. Unless your going to run it to a shop everytime it breaks your going to have to get your hands dirty. You did buy a hot rod of a bike.

Let us know how the EHC replacement goes and how long it takes. There's bikes at the dealer here that have been sitting around since summer waiting on EHC's. I would have to get proactive and spend the money for a wires plus kit. Spend $500 and ride now or wait until who knows when and ride later.

You guys dont get it...No bike under warranty should sit at the Dealership for over 30days...of course, mine have only been 1 week, but BDM must provide a solution to the downtime...I'm confident they will get me up and running soon OR provide me with something to ride in the interim...Its not my fault they're inventory got low and they waited til they were fresh out to produce new computers...For those who need business advice, don't wait til your "well run dry" to look for more Water...And No, I didnt pay 30k...I paid 21.5k.....But 2 years ago, folks were paying 38K or more for a K-9 EFI...Also, for the Record, I have all the tools I need and I'm a decent mechanic...But remember, I cant touch my bike! Its still under warranty, so I have to let BDM service center screw with it....I may not be riding for a while, but it's called holding a company responsible for taking care of customers...I'm pretty sure they will take care of me soon...

hey some guys these days don't like to get their hands dirty, they should ride vespas!
Is this a "Big Dog" Forum, or a "Self Modified chopper", which started life as a Big Dog Forum...Seems to me Big Dog is taking credit for everyone's Mechanical and financial ventures....

Miami, will you please set us straight. Who modded your bike? Who added the so called bling bling lights? How were the lights wired, were they spliced into existing wire or directly to the battery. Even wired directly to your battery can cause the ECM to fail if the batteries weak. Were any other electrical mods done? This can help us further understand and maybe help out better. I noted a lot of things have been done to your scoot but would like a full view in case anything was over-looked. You said that your ECM went out, just would like to know exactly what happened here. I'm not trying to be a smart azz, just would like clearification on what all was done. The bling lights may have voided your warranty and could be the cause of the ECM malfunction... Just saying...

Miami, dude forget the wise cracks, people here are trying to help ya. I think from previous posts there has been mods done to the bike since you had it. BigDog factory could say screw you we ain't fixin nuthin' since the mods. You said the bike never ran good to start with, was that brought to the attention of the service center before mods were done? You were joking about the "loaner bike" right? I've had Honda's, kawa's, and Harleys and have never got a loaner bike, this ain't your local Ford or Chevy dealership. Did you research BigDogs before you bought one? They are in deep trouble just to stay afloat, if it takes time to get parts than that's the nature of things. Look I've owned many bikes but always wanted a VRod, finally found a great deal in '08 on an '04 with only 116 miles on it, yes 116 not wrecked miles. On my 480 mile trip home it died in rush hour traffic when I was three lanes deep, not fun. I managed to get to the side of the road called in the calvary to bring a trailer and took her home, damn I paid cash too. Didn't get too frustrated, since my bike set up for 4 years with no TLC, I wasn't surprised. Turned out to be garbage in the injectors. Since you are mechanically inclined use your common sense and if you have to get involved directly with the BD Factory for support than do that. I had to intervene on my own as well to get things done to my satisfaction when I thought my service center was slow, even though I can't complain about their work. Don't mean to beat a dead horse but you said you can't touch the bike while it's under warranty, but in fact you have when mods were done. Many people here have multiple bikes and don't mind the down time when they have another bike to ride, as I do as well. These bikes do require more attention than others, so if you don't think you can live with that you may want to look at a RiceBurner, not to be derogatory 'cause I ain't a brand bigot, I like them too. I hope you get your issues resolved and can ride soon and many here know more than any service center tech. I've learned much from reading the "how to's". Good luck. :up:

How is Big Dog taking credit for everyone's Mechanical and financial ventures?????? Also this site isn’t sponsored by Big Dog.

Don johnson,

my best advise to you is to ask the mods of this site to delete all your threads.

BD monitors this site and they WILL deny warranty because of info they find here.

just saying. :rolleyes:

I think many of us on here absolutely get it and are trying to help. As some on here have said many of the problems can be a easy fix. Some of the problems are brought on yourself by making mods to the elec system and not doing it properly. At any rate I'm sure I don't need business advice from you. First of all I do plenty of research before I make a purchase and know what I may be getting into. You bought that bike for 21k because the economy is in the toilet and BDM is struggling as are many others. A quick search on the Internet or a few conversations with other owners at a bike night would have done you some good. BDM obviously has some back ordered parts issues. All I'm saying is if your really having EHC issues and are wanting to ride you may have to be proactive and spend a little money outside of warrenty to get it moving "wires plus" etc. Warrenty doesn't mean shit to me if my truck is in the shop waiting on back ordered parts or keeps having reoccurring problems they can't fix and all the while my $2000 a month payments are coming due.

I would start over with the original problem and the mods you did in the order you did them and see if we can help you out. As far as the EHC goes I guess if it is "Caboom" then you can probably wait 6 months for a new one and scream at the dealer or try the wires plus and get to riding. Good Luck.
