Jeez fellas, way to hijack my thread...
Seriously though, great to see more discussion, interest, and cool ideas (many of which go WAY above my head
). Not to mention I've hardly been punctual with this thread... but now I'm finally back for an update.
So I ended up cutting the black resin from the old Thermistor/Thermostat and used the new ones simply by sliding them back in (they're held tightly enough, and the fan still operates as it did previously). I then drilled new mounts in the chassis, and stuck the new boards in... but (there's always a but
), the longer boards now created a clearance issue with the +/- MB wires to the +/- back panel terminals and the cooling fan. So after some strategic trimming of the fans shroud/frame, I managed to sqeeze it all back in, and in the end I just cable-tied the front panel voltage switch board through the grill/holes in the front panel (saved me buying a glue gun for this one job!).
And then, it worked! And has been working fine for 8 months now.
To note I did get an explanation (of sorts) from Cher on the mysterious eye terminal that comes out of the middle of the CB. Quote - "engineer said the cable is protecting the board when home AC power switch to inverter.
" So seems it's Battery Charger/UPS function related?
Also I cant recall original readings (I recall others saying upto 8 Amps?) but with new boards idle current now sits at about 2.6A. Not great, but I think it has improved. The only thing thats still not fixed is the over sensitive, over voltage protection. But now living as the run-about inverter for job's around the block (bore/transfer pumps, circular saws, cement mixer, etc) it been well worth the investment.
However, there is one thing I love more than my LF5000... my LF8000!
Idle current has definitely been sorted here... 0.6A! And it's soo quite compared to the hum of the LF5000, and easily handles everything I throw at it. Again the only issue is over voltage - that's next on my todo list for both units. I'll post another reply soon with a few questions for the local electrickery legends to help me nail that issue. Then I should be humming along very nicely indeed!
