MANTI5 Posted October 14, 2013 Report Share Posted October 14, 2013 Found a little more out from a poster on another car audio forum: There is a black box on the negative battery terminal called a micro shunt. It can handle up to about 1200 amps peak current and 300 amps constant. Here is a spec sheet on one: http://delphi.com/shared/pdf/ppd/sensors/et_ivt.pdf Seems there could be two ways to hack this. 1) measure the voltage going out on the sensor wires when A/C and/or lights are turned on. Then use a resistor to sum in some voltage to emulate and tie it to a switch. You would have to do some wire tracing and measuring with a DMM.2) Find out how much load current must be pulled from the negative terminal to trigger the alt to full volts, then ground some of your system components (maybe front channel amps) to the lug on the ground sensor so the current is detected and will kick in the alt.Just a couple of ideas.

Just a couple of ideas. From the datasheet it looks like the sensor outputs Local Interconnect Network (LIN) or Controller Area Network (CAN) digital signal back to the main control module. This may not be as easy to hack as the last gen ELD. The sensor on my 2012 CR-V is completely sealed. I'm going to do some o-scope probing on the output this weekend. It looks like these are used on all the new generation Honda's, so we need some good data on it. Link to comment Share on other sites More sharing options...
MANTI5 Posted October 17, 2013 Report Share Posted October 17, 2013 Yeah, it should be canbus from what I've read. Thanks for the help, every little bit we can find out will be helpful as I'm sure more and more vehicles will be headed in this direction. Link to comment Share on other sites More sharing options...
HatersGonnaHate Posted October 17, 2013 Author Report Share Posted October 17, 2013 I just think the big factor is, the people with the newest generations still have some kind of warranty on their cars and haven't wanted to void the warranty by adding aftermarket alts and whatnot. And they probably have no idea what the eld does, nor do they care or even know about it. But, eventually, the info will pop up. Just takes patience!

949 Posted November 5, 2013 Report Share Posted November 5, 2013 hi, I was wondering if you could give me directions on how to do it on my accord? I am one of those who need exact directions and any diagrams/pictures. so please bear with me. car: 2001 accord v6 ex. I want to do the mod WITHOUT the relay or switch. i don't mind having the alternator on H.O. all the time. the mpg doesn't bother me. so im not sure how to do it from that. i assume its a lot more simplier because im not using the switch method. thanks for any help or pictures that will guide me.

HatersGonnaHate Posted November 5, 2013 Author Report Share Posted November 5, 2013 http://www.hondaaccordforum.com/forum/audio-visual-electronics-10/honda-electrical-load-detection-eld-bypass-32726/ I just replied to your pm. This is the exact guide that I used, and this one is specifically designed off of a 2001 accord.

949 Posted November 5, 2013 Report Share Posted November 5, 2013 thank you for the reply!!! i am actually seeing if i can leave out the relay part of this mod? is it possible to just do it with out the extra relay and switch? im not hooking it up to the stereo or a remote. i don't mind having it on all the time.

949 Posted November 5, 2013 Report Share Posted November 5, 2013 I just noticed that your diagram is easier to understand, and for me that's a plus, than the original one from keep alive. I was thinking about it after staring at the picture. why cant I cut the pcm wire and then directly connect that to the resistor. and take the resistor and tap onto the ground? wouldn't that work?

MANTI5 Posted November 6, 2013 Report Share Posted November 6, 2013 Any new info on the 9th gens? DC Power has h/o alts available but they're pricey, sure other companys will have them before long just need a bypass now. Link to comment Share on other sites More sharing options...
