    Hi all,

    I have an 04 BD Chopper RT frame. I'm pretty sure my EHC is done but I want to run it buy you guys before I spend coin I don't have. Bike is never left outside (only sees rain if I'm already on it) I've had trouble starting the bike, new battery voltage is good starter motor working. It does start but when it when it won't if I leave it a few minutes and try again it will usually fire up (not flooded also checked the plugs no issues) recently I've had the bike just shut off a few times while riding (scared the crap outta me) then have had trouble starting it up. I think it's my EHC, anyone think otherwise? Also I'm looking at the Big Dog EHC RIP kit but I see guys talking about the WSW kit. What do you recommend and why? Keep in mind it's an 04

    My 07 k9 had 4600 miles on it when I bought it a couple months ago, never in rain never even washed just polished, it sat for the last two years but ran perfect on my first ride it cut 2-3 times but always started back up, figured was bad fuel drained it put fresh in it fired right up again , it sat for 2-3 days went to start it no power and after 10 seconds horn went off so I grabbed the axle ehc I had brand new installed it problem solved so it sounds to me the beginning of ehc failure , axle has a plug and play also for the 04 model I highly recommend it

    Lots of threads on this topic, do some searching and reading, there is 3 options, ECS, RIP-1 & 2 and Axels, choose which is best for you. I personally have DOC's ECS.
    First I would verify that your battery is good meaning have it load tested, and 2nd, when its running do a voltage check to make sure its charging.

    Start with the simple things first. Do you have a red light on, on the ignition module. It may also be a broke wire in the ignition circuit. That's what I found on my 04.

    New battery fully tested, I checked my lights (will check again) was green. Ignition circuit is a great idea I'll give that a look but would cause a shut down?

    Ignition box, is the silver box. It has 3 lights. red one shows it has power, the other two indicate which cyl. is firing. The cam sensor is located in the nose nose cone, on the right side of the engine. Providing your 04 has the 107 ci. engine

    Thanks. Been told my EHC is bad on my 04. Everything works but the headlight, and she is slow starting.
    Thanks for all the support everyone gives.

    I don't think it's the EHC, its either ignition or fuel

    My 04 has the RIP1 had to replace the original ECH because the the thunderhart ignition module was not getting enough voltage from the EHC and would not function properly and bike would not start.
    A year after replacing the EHC the bike would die and sometimes start back up and sometimes not until a few hours later. I did notice that again the thunderhart ignition module was not acting properly the red light would come on if I press the run button and go out as it is supposed to do but would not flash while cranking, so I replaced the cam sensor and everything works as it should.

    Yes it's possible that the EHC is bad, I'm just saying, let's check the easy cheap possibilities first.

    Thanks, that gives me a few things to check. I did check the fuel already replaced the plugs and ran a tester. I also replaced the battery and tested the voltage. I haven't tested the ignition module. It's -10 here right now so I gotta wait a few days so I don't freeze
