One of my first EPS controlled boats would flash a code for not having enough voltage to the EPS unit, after running the stereo amplifiers too long. The EPS systems require and consume a lot of power, and if you loose it in one of the large systems, as in the systems boats use, its next to impossible to steer. They went as far as putting a pressure relief valve on some models, to bleed down the system and use as manual. How long have you been running those HID's? I ran HID's for one weekend, and they really took too much power, my voltage gauge normally showed about 13.8 (rectifier charging only) with the lights and heater on, the HID's pulled it down to just over 12. It was too much, even with the alternator turned on and running, it charged under 13. It barely started after we stopped for a break. So I ran home with no heat and only dims. I had 55 watt HIDs that pulled 18.5 amps with all 4 on. My stock 27 watters pull 9. Add that to the dashlights, taillight, heater, ignition system... They take a lot to run and maintain a battery. And as the battery ages, it won't hold the amps it did when it was new. A 300 amp battery may only hold 1/2 the amps after a few years. Do you run your batteries in series or separate for start and accessory?
Throw a fluke on the battery. See how many amps are in it. Then start it, turn on the lights, heater and turn the wheels. You'll be surprised at the drop. I believe the rectifier puts out 25 to 30 amps. I was pulling over 40 amps with heat and bright lights on and I don't have power steering. Getting rid of the HID's and putting in my stockers back it brought it below 20 amps being used and it's been fine, since.
A few idea's. Hope it helps!!!
