Has anyone successfully bypassed the low/high charging functionality of the charging system? Apparently the ECU puts the system in a low or high charging mode based on several factors. This results in the voltage varying from as little as 12.6V, in my case, to 13.9V. The voltage can remain at either level for an indefinite amount of time. This is affecting my audio system and I want a constant 13.9V. I imagine there is a way to trick the system into charging at full voltage continuously.

I don't think opening up yet another thread and then bumping a 5 year old thread is going to help you.


have you tried Googling to see what you can find there? https://www.google.com/search?q=bypa...hrome&ie=UTF-8

My fault. Couldn't find my other thread. Please delete this one if possible.

Well, if anyone else is curious, on the 2011 Acura TL, apparently all you have to do is cut the blue wire from the ELD sensor connector and connect an 820 ohm resistor between the blue wire and the black wire. The ELD sensor is located inside the fuse box in the engine compartment. Then your voltage will stay at the highest level continuously. I'm not sure what purpose the 820 ohm resistor serves if you are cutting the wire completely and leaving one end open circuit. Seems like you could just disconnect the sensor and it would accomplish the same thing. I'm sure it will become clear.

Here's a good explanation: Honda-ELD

Still not clear what the 820 ohm resistor does if the output wire to the PCM is completely severed.
