I just installed the EB 3CS kit on my 2015 DL650A. I also have the EB H4 headlight relay kit with 3CS connection option. The main fuse in the 3CS is 30 amp, but what size of fuse should I be using for the H4 relay circuit on the 3CS?

The direct-to-battery H4 kit comes with 2-15 amp fuses, and the stock fuse box has 15 amp fuses for high and low beam respectively. So I'm thinking a 15 amp fuse is required in the 3CS, but I'm not certain. I couldn't find any answers on the EB site.

15 amp.

Math:
60w per OEM light (max) x 2 = 120w
120w/12v = 10

You have a theoretical max pull of 10amps. 15 will cover it.

Or I could be totally wrong and someone will come along and correct me :grin2:
