Our first shipment is arriving today folks.
The 58c will work in your 2010 bagger but you will need to send the OEM EHC to us so we can swap the d-sub shells from the OEM to the new module.
This is good news Curtis...I just sent you an email asking about mine...lol

Hi Guys,

hm, sorry, I have to tell to you that I have sended the first shipment with the upgrated EHC to Curtis, but they are still in the old housings, cause I simply have a delay to get the new boxes in time. However, the new electronic is implemented in the delivery what Curtis got yesterday. So, everything else is as described. I was a bit fast with my post yesterday, cause I was a bit proud of the product what took me about 4 months develope time with fun and tears... I hope it would be ok. Sorry again !

All the best!
Axel

That’s awesome, great features. It says a lot you continue to support and evolve your module.

I’d love to learn more about the Bluetooth module and how it could be used for other applications.

Hi Jwooky,

Thanks for the reply. The bluetooth module is not complicated. It´s just a low power Bluetooth 4,0 module with an implemented 12 Volt to 3,3 Volt converter, cause the usual bluetooth modules work all with 3,3 Volt. The 4 cables are: + 12 Volt, data out, data in, ground. The data speed is 9600 baud and I just send 3-5 bytes from the phone to the module / EHC per every request. You can use any kind of bluetooth terminal app to communicate with the EHC, no matter what operating system is installed.

I have first thought about to put the module in the EHC, but the position of the EHC in the bike will shield the high frequency waves. So, I decided to make an extra module what allow a better position under the seat outside of the battery box. I hope it is ok.

All the best!

This is actually great news. I'm pretty sure I'll need to replace my EHC in both bikes. I recently found out I have I think what they called a Gen 1 half din ECH in my 06 mastiff. I was told it was probably a left over one they put in my bike for the EPA de-tuned TP rocker box engines.

But I do have a question maybe someone can help with. My aftermarket LED's controller box has a single wire that comes out of it. What it is for is you hook it to a 12 volts when the brakes are pressed and it will turn all the LED's on my bike red kinda like a third brake light. The only problem I'm finding is that the wires going out to the rear tail lights are sent from the ECH or micro controller. theres a ground, run and turn. to each light. the controller is what tells both rear lights to come on when either brake switch is pressed. where can I find a 12 v power supply that comes on when either brake switch is pressed. Cause if I read the wiring right its a ground that goes thru both switches and when the controller reads the ground on either or both switches it sends out a positive supply to both turn wires. but I cant hook to them because any time I put that turn signal on the LED controller would read the 12 volts and make the LED's flash red with the turn signal.

Don't hook it up. Bad idea. I had a meeting at the factory a while back, LEDs and neon lights were discussed. The frequency that neon puts out will mess with the ignition system. And tying into your wiring system, when putting LEDs in could overload your EHC.
That being said, I don't know about Axle unit, and hooking up that wire. Ask the Kaptin when you talk to him.

I will do.

Hi Mastiff Rider64,

Thanks for the question. It shouldn´t be a problem with the new box to change the rear light function from US mode to European mode. In this case is the tail light dimmed to 30 % if no brake switch is activated and it light up to 100 % when you brake. So, you can wire your center brake light together with one of the red cables what go to the tail lights and use the tail lights as brake lights as well. However, it´s made for the European market. We often use the same high brightness led inserts for the tail light function and brake light function as well and have the direction indicators separated from the brake lights. You just need to change the program option 3 in the manual from US mode to European mode. The new EHC have the US mode activated by default. So, you might need to change it to the EU mode if you use other led´s. I attach the manual.

By the way, I had send the following led boards to Curtis a while ago: http://elektronikbox.de/bdled_uk.html . I made the boards for my Ridgeback more than one year ago, cause I was not very happy with the brightness of the original rear light boards at this time.

All the best!

Thank you so much. It makes sense as to why i guess with my factory ECH I could never get this function to work on the LED controller for my aftermarket LED's.

Hi Mastiff Rider64,

Thanks for the fast response. You are right. it will not work with the original EHC. We have the same challenges here in Europe when we import US bikes, no matter if Big Dog, Harley Davidsons or American Ironhorses. However, you might can use my Rear Light EU module ( http://elektronikbox.de/rearlight_uk.html ) for a conversion of your bike to other led inserts. I sell a lot of these modules to importeurs here in Europe. It is cheaper compare to a new EHC and I don´t see a reason to change your old EHC against a new one as long as the old EHC works correct. Just feel free to ask Curtis if you are interested and I can put a module in the package when he make his next order. This will save the cost for transport to US.

All the best!

A warning to those with OEM EHCs, beyond the issue with the OEM charging system and if you would like to keep your stock EHC and not spend money on a new replacement. Do not tap into the harness for anything. The stock harness and OEM EHC were designed to handle only the loads that the stock system puts on them. If your going to add anything electrical do it outside the stock system with it's own fuse and relay.

I may have missed the discussion earlier in this thread, I see now there is a requirement to change out the OEM voltage regulator to keep the EHC(Axels) warranty valid. I suspect this is recommended for earlier EHC units too? Nothing mentioned about this in the installation instructions in earlier units(Axels). 2008 Ridgeback.

Hi Kobi,

Thanks for the comment. Yes, we got back some defect EHC resulting from defect OEM voltage regulators, what had supplied the EHC (and the other electronicparts in the bike as well...) with voltages sometimes above 40 Volt. This is too much for the EHC and for the other electronic parts. That´s why I have implemented a voltage measurement in the new EHC what switch off the ignition if the input voltage is above 18 Volt for more than 1 second. Two short horn signals indicate also that overvoltages above 18 Volt were present. This should warn the user that there is a problem in the charging system and not somewhere else.This might prevent the EHC against damage from a defect charging system, but I had (fortunately...) not the opportunity to test it out in my bike. That´s why I agreed with Curtis about the warranty limitation in this case. The EHC will withstand voltages of 18 Volt for some hours and 24 Volt for some minutes, but the EHC might fail if overvoltages of 40 Volt are present for a shorter time than 1 second. These overvoltages could also appear if the battery have no contact to the charger for a short time and there is no significant load what hang on the charger.

However, I don´t let you hang in the rain in case of EHC issues but pls. give me and Curtis the chance to decide in case of overvoltage issues to change the EHC for free or not. I hope it helps.

All the best!
Axel
