SWCG not showing 0 amps but not generating

So, if I understand this correctly, if I’m reading more than 0 amps then it’s *not* a K1 relay issue?

Moved from here.
Not necessarily. Bad contacts on a relay can have a non zero resistance which would cause a larger than normal voltage drop across the relay but current would still flow albeit lower current. These symptoms would be similar to a failing cell so it is always a good idea to test the cell to make sure it is in working order.
