Just wondering about all your 12 volt items you say ur useing, were is your 12 volts coming from, you stated that you have a 6 volt system, 1156 bulbs are 12 volt and be be very dim and your cell charger and radio are probably 12 volt also. Acc power from ign switch to fuse panal is correct, but were is the 12 volts coming from. My posts are going to be kinda speratic cause I am working most all day and night but I am an auto and truck electricain and have been for 30 years. So I like getting involved in this stuff.
Every thimg I've seen so far on this post is good, just getting confused about your 6 volt system and your 12 volt components. I have done several rewiring jobs that we changed out all 6 volt lighting to 12 and used step down voltage boxes to run original 6 volt ignition ect. but a 6 volts system with 12 volt stuff don't compuut.
