What's this? (Gen. control box)
After the mysterious starting issue, discussed earlier, I decided to clean contacts in the control box. I disconnected the shore power, but not batteries. I used a voltage tester (light) to check the terminals and contacts that I could see before disconnecting and cleaning contacts. My tester showed no voltage.
To the right of the three relays (see photo), is a rectangular devise with two lugs mounted vertically. I removed the top red wire with yellow collar and touched the side of the "box" that the lug is mounted to with a resultant arc - similar to crossing battery terminals. Again, I had tested that lug with the tester (which was working properly) and it showed no power.
I put the wire back on and checked to see if I could start the generator. Not surprisingly, the pre-heat would not come on. The two circuit breakers (switches?) mounted on the front of the control box had not tripped and the 5w and 10w fuses were intact.
Two questions: What is that black thing (for lack of a better word) with the two lugs? Is there another fuse or circuit breaker I need to check (the 12v fuses under bed are good)?
