Volts but no amps?

Forget about being incorrectly wired, as i keep saying, that and the failure to display alternator amperage is irrelevant to the current problem, that's a separate issue for another day.

The current problem is the lack of any reading of input from the solar controller. If the solar controller has failed in such a way that it is allowing the full output of 215w of solar panels to be fed to the batteries unchecked it will cause a lot more damage than a fried controller. I cannot see the batteries surviving such treatment, let alone electronics.

I'm glad someone agrees. As the battery monitor's not reading the input amps, then even if I were to re-wire it right now, I wouldn't know if I'd done again good, the alternator input would just be another bucket full of amps that I couldn't see going in.

Freeflowing the solar input (with care) doesn't seem to be causing any short-term problems; we're disconnecting it if nobody's aboard and/or if we feel the battery voltage reading or temperature's are going too high. Our domestic battery bank's 450 amp/hr, plus another 100 amp/hr from the start battery if we connect that in, so with a peak solar ampage delivery of 15-20 amps, we're only pumping-in around 3% of total, albeit at a higher voltage than we'd like; the highest battery voltage reading we saw yesterday was around 13.8v, so still lower than when the alternator's spinning.
