Just curious what the typical volt meter reading is:
1) when you're sitting at the stoplight 2) cruising down the boulevard at 3-4000 rpm Trying to see if I'm seeing typical or low readings Thanks I just recently noted a low charging issue that I believe came down to an alternator/voltage regulator mismatch. I was using a Bosch VR with my Motorola alternator. Now I've switched to a Marchal VR and the charging voltages look better. About 13.75 volts while cruising. |

As far as LED current is concerned, my brake boards burn about 5W when on. Turnsignals about the same. So worst case is sitting on the brakes with turnsignals on. That would be
5W x 2 + 5W x 2 = 20W which is a bit lower than 2 amps. Not sure about LED headlights. I would assume 15-30W each. 1.5-2.5A each. |

But we still have some higher legacy loads: Anyone ever meausured the following items? Wiper Motor - TBD Ignition coil - TBD Radio and/or auxillary amplifiers - TBD. I know my modern radio is fused 10A (4 ch. x 25 watt RMS). Probably draws 4A steady state. Fog Lamps - depends of LED or conventional. Other goodies - radar detector, phone charging, etc. |
