So recently, I had a melt-down with some of the monitor wiring on the cluster… to counteract that, I have some parts on order (RS Components annoyingly seem to have changed their shipping policies, so I suspect I’ll get them Monday)… namely some thermocouple extension cable, some small 250mA fast-blow fuses and suitable in-line holders.

In the meantime, I’m doing without the power controller, just turning the voltage down on the mains charger so the solar controller did most of the charging.

This, isn’t terribly reliable… and for a few days now my battery voltage has just sat at a flat 12.9V, which is the “boost” voltage set on the mains charger.

Last night we had a little rain, and today I see this:

Battery voltage today… the solar charger is doing some work.

Something got up and boogied this morning, and it was nothing I did to make that happen.  I’ll re-instate that charger, or maybe a control-only version of the #High-power DC-DC power supply which I have the parts for, but haven’t yet built.
