Charging upgrade
Today I upgraded the charging system in my 72 C10. I have an LS swap in it. Before I did the work today, I was reading just under 13 volts in the cab with windshield wipers that were incredibly slow and caused almost a 2 volt drop in the system when operating. After the work, I’m sitting at 13.8 volts at idle and my wipers now operate at normal speeds without a voltage drop. Below is a diagram of what I did. I got this great info from mad electrical.
