Double check my math?
Okay, so I am in the process of finishing my front light bar, and I decided to run the numbers before I install my new lights.
(all numbers rounded to the nearest tenth for ease of calculation)
R1 (Hella 500ff1) = 0.6 Ohm
R2 (Hella 500ff2) = 0.6 Ohm
R3 (Hella 700ff1) = 0.7 Ohm
R3 (Hella 700ff2) = 0.7 Ohm
^ This all stand to reason, seeing as they are the same light bulb, ideally, pulling the same amperage.
It=88.88(rep) A @ 14.4v
That is a lot of amperage to yank off of a stock alternator.
Need an upgrade much?
