[QUOTE="johnnyvolcom5, post: 7648874, member: 605736"] ok so here is another problem i may be running into in the future. I should prob post this as a new thread but since this one is already started i guess ill try here first. Apparently hondas manufactured for use in the US have something called an ELD (Electronic Load Detector) that, if im understanding correctly, basically tells your alternator whether or not to be in "high output" mode or LO mode depending on what you have running. For example if you were driving in the city at low MPH with nothing on in the car, the ELD would kick in and say low output mode, making the alternator put out only 12 or less volts to battery. The problem is the ELD doesnt pick up things you add to the battery before the fuse box, meaning it wont know your amps are on and drawing power. WHich could lead to undervoltage at amps ect. So here is my question, can i just run speaker wire from my battery terminals to my DMM probes so i can monitor the voltage while driving, or can i purchase a reliable voltmeter i can hook up? I want to know if my car is kicking into this LO mode while driving....i tested my battery with car idiling every minute or so for 20 minutes and it was always normal but maybe changes while driving.
