[TR] Power budget woes, was re: driving lights

[Joe Laurito]

And if you like to stay warm in the evening, don't forget to save a few amps for your heater fan! I did the same math and came to the same conclusion. That's why I bought an alternator conversion from British Wiring.

Subject: [TR] Power budget woes, was re: driving lights



I had written a thread about how to mount driving lights on my 4A. After some brief thought, I suddenly had a sinking feeling about where all this light was going to come from! 



The driving lights are rated at 55W/12V, and so are the headlights. that means each bulb will draw 4.6A. That amounts to 18.3A when the driving lights are in use. The generator is good for 22A. That means that I am left with 3.6A for EVERYTHING else. The ignition alone is at least 2A, and all the running lights are certainly at least 3 more amps, and probably double that.. 



My energy budget goes into the negative zone as soon as I use the driving lights!!!! I wouldn't be surprised if I am drawing 5+ amps more than the generator will supply! Not a problem if I had an alternator.... Which I don't. 



So, I just ordered the H4 lights from BUSDEPOT as mentioned in a previous thread. I think I will get the relay wiring harness from VB. Moss has a kit for headlight relays what costs $130! I wonder what the extra $90 gets me compared to the VB kit.
