i plan to build a bulb discharger this weekend and would like a little help from you guys
1. how many bulbs shall i use? i read somewhere that a single bulb pulls 2 amps, so ill need 10 bulbs for a 20 amp discharger, right?
2. i will use 12v automotive bulbs. shall i use a single or double contact bulb? is there a difference in their amp draw?
3. if i use a double contact bulb, how do i wire it? i know i have to wire them parallel but how do i do it? do i wire both the contacts at the bottom of the bulb together with all the other bulbs to the negative lead?
i found my old deans black box 2 and i will be using this as a cutoff device
thanks for any info
