Had a short in my a/c rotary switch at neutral wire which melted inside of switch. Put in new switch from blue seas, along with new wiring from switch to main circuit breaker. Put other wires from gen set and shore power in correct positions, I am only getting 70 volts on my digital multitester. Have new smart plug shore power cord and marina checked power box and shows 118volts at box and at cord end. Could problem be in the boat inlet or when the short happened it damaged my main circuit breaker. I think the short occured when I turned my cruiseair heat. The neutral wire was a bit loose at the breaker. any ideas on low voltage. I am not at boat but plan on going down to run genset and see what I get
