Bypassing your EHC

Well, got the word that my EHC is good, but there were some major electrical failures, so Curtis is wiping it clean and re-loading it and I am checking all my wiring for bad connections, as you can see the solenoid connection was not good, anyway I am gonna re-install my EHC and change one other thing, I don't want to be at the mercy of the EHC anymore, so I am gonna do what I did to my 05 Bulldog some years ago, I am bypassing the EHC and powering my ignition right from the battery! Then I am installing a slam button so I will always be able to start it! Even if the EHC fails, I will be able to get home, anyway here's how I am doing it, the toggle switch is replacing the old key switch to power the lights, speedo, etc....





First you need to pic up a few supplies!

I removed the battery box so I could access the starter, if I wasn't installing the slam button I would not have done this.

Next I have been checking all my connections with my Multi-Meter and visually, looks like one of the terminals on the starter was damaged and had a lot of corrosion on it!

This is how it should look!

I removed the damaged one and hopefully Curtis can get me a new one or I am gonna have to figure something out, maybe the harley shop might have something similar?

Ok, enough of the starter b.s., lets get on to the "old school wiring!" Haha! Here is the toggle switch after I mounted it under my coil, I used a thick piece of plasted to mount it, did not want to use anything that might conduct elec., probably don't matter but that's what I had around the house to use, I know it's fucking "blue" Ker! Lol!

The wires are connected to the original key switch wires.

You see the new key switch is installed also, that thing fit perfectly Ker! Just like it was made for the bike!

Next I crimped some connectors to the wires so I could remove the coil cover without cutting wires!

Now I ran the two wires up the backbone and out were the original wires are and put the same connectors on the ends.

A litte shrink tubing cleaned things up nicely!

Next I mounted the coil cover!

That key looks good don't it Ker! And it's cheap! As you can see the toggle switch is not visible unless you really get down and look up under there, but is really easy to access.

Ok, that's done, I am ready to head to the battery box and do a little work, here is the other end of the postive power I am pulling directly from the battery, that's a 15 amp fuse in there also, see the wire shield I put on there, it was the old VR shielding that I saved, works and looks great!


Well, that's it for now until my ehc and slam button show up! Also just for shits and giggles I did a test on all the connections with the M.M. and everything was good!

Just curious because I'm not exactly follwing, is the toggle switch spliced into the key switch and then ran to ignition module?
Thank God I am not the only one!!!!!! I was starting to worry...


Here my questions on a PM to John:

Well, I just readed (twice) again..... Nope!!! I have not a clue what the F you've done there... you talking about "wires"...

1. what wires?
2. new, old?
3. where they come from and going to?

Sorry..... but not being done much electrical stuff before I have no idea of what wires you are referring to. you just mention wires, but there are dozens of wires.... LOL

No they are two separate systems, the toggle switch is replacing the original key switch, it only powers the ehc, the new key switch powers the ignition only, what I did Tyler is find the power wire comming from the ehc and going to the ignition and the I cut it and took the end coming from the ehc and folded it back and srink wrapped it, the took tbe other end that was going to the ignition and ran the new power wire to it that was coming directly from the battery via the new key switch!

I've been talking to John via PM but I still don't get it..... Its like when you ask for directions and the person who is giving directions to you is assuming you are a local and you know all the landmarks! To give directions is not easy either....

John gave me permission to post his Diagram... it might help someone.

So basically you have hot wired you're ignition system with the new key switch and every thing else is powered by the toggle switch and are still controlling the starter selinoid with the ehc. Is that correct?
