I got my R.I.P kit from Curtis about 2 weeks ago and what a difference! He was even on the phone with me for like an hour just shootin the shit. It took about 2-3 hours to do the install but was worth every penny! I can finally ride ANYWHERE without the worry of it dyin on me.IMG_4998.JPG

Gen 2 connects to the Backbone harness verses replacing it as the Gen 1 does.
Some say its an advantage but the only advantage I see is if your back bone harness needs replacing which is not always the case.

Can't argue with that statement.
But until several have been in the field for awhile, with no issues, I'm not so quick to jump in.
I've always wondered why TH could build something somewhat simple and not have issues but BD just didn't seem to be able to get it right.
Of course there is a whole lot more to the story with owners doing shit they weren't supposed to be doing too.
I was working on something similar but just don't have the education, skill set or time.

The last 5-10yrs before I retired my company thought it was better to throw 20-30 people on a design project, and all they accomplished was having meeting after meeting and putting so much bullshit into the design than what was necessary. They put MFG engineers, Electrical engineers and Design engineers on the project together and it took years to finish a project. It was over thinked:oldlaugh:
Prior to that we designed the machine and told the Electrical boys what we needed and it was out the door in 6 months and it usually have thousands of cycles on it from testing.
BD wanted all that data stored for warranty claims from people abusing and not breaking in correctly.:oldbang:

I think this thing Axel is working will be the cats ass, to be able to just plug into the OEM wiring harness will make it a 10 minute install:whoop::old2: how kool will that be:boing:

I bought the 50pin connectors actually still have them.

Before all these other options were out I was going to make a plug and play for the WP. Where you could just solder he wires of the WP outside of the bike then install the WP and just clip it in. Badda Bing. When I bough my second bike PO already put a PDM in so I never got to test it.

There is definitely connectivity issues with using that connector which I assume WP, RIP, DOC all wanted to avoid. However, it's almost idiot proof.

Hi,

I just want to give a small update. I potted the first EHC today and found out that the internal blue status led´s of the outputs are diffult to be recognize when the potting compound cover the led´s. So, I´ll laser small 5 mm acrylic pieces and put it on the led´s before potting the EHC. I think this will help. An other issue at the first test device was the paper tape what covers the threaded rivets and should protect the thread against the potting compound. However, it was not working perfect. I think, an other kind of tape will work better. I attach 2 photos of the EHC together with my first provisionally EHC tester.

However, We´ll make the final test together with the 2004 EHC in the second April week and I think, that the first devices will be available. The EHC2004 with 1 connector should be ready in April as well (if I haven´t put some funny mistakes on the 2004 board...)

All the best and happy Eastern!

Thats enough to give a guy a chubby, looking at those pics Axel brings back a lot of memories from when I designed tube feeders and robotic grippers to place those connectors on the PC boards before wave soldering.
Keep up the good work,:old2: and Happy Easter to you also:whoop:

So why didn't you build this for us 5+ years ago asshole? Lol

Alex I am curious how this unit is going to stand up to, and handle, a situation where the starter has a loose connection or a short and draws a huge amount of amperage through the unit during start up. BD built in a safety mechanism for that.

Yes its a mosfet breaker but in the BD module they had software protection also so if the system exceeds a certain amperage or the module sees a short in the starting system it just refuses to allow voltage to the starter solenoid.
Personally I don't like it built into the module as it is too easy for it to cause damage to the module.
When I build the TH kits for the 03 bikes I use a secondary external starter relay with a 30amp fuse to take the load off the module.

I don't know about the RIP, but I would then assume thats what the fuse is for on the ESC that I have. I'm not a sparky but it don't hurt to ask:old2:
