Fridge / battery loading

[tonyg3nwl]

Hi Again. I am still on the trail of possible battery failure, but have now concluded that the fridge is nothing to do with the original problem

 

Yesterday I carried out a series of discharge measurements/tests over a six hour period by turning on all interior lights and measureing volts/amps at hourly intervals. After the 7 hour the internal lights were off and control panel showed battery low/ sysstm lockout.

 

Terminal voltage measured at battery terminals, still showed 12.2 volts, so I thought about it overnight and investigated again today. The panel reset ok and lights again worked, battery volts 12.2 on load, panel indicated battery 90 %, this after overnight rest with no charger.

 

While fiddling with wires around battery area, The control box clicked several times, and led me to think dodgy contact somewhere. I am hoping that by changing the push connectors on the fuse providing the sensing voltage, that the problem has been resolved. I cannot reproduce the intermittent symptoms again yet. Panel now indicates 90%, voltage 12.2, and lights functional. Charger now switched back on to fully charge up ready to run another soak test.

Hi again.

 

12.2 volts is a heck of a low value for a battery supposedly at 90% charge, on load or off load. Just my immediate thought while I ponder the rest mentioned.

Hi once again.

 

Yesterdays further tests for a 6 hour test from full charge with all lights on, the Panel still showed 100% at a voltage of 13.5 volts.

 

Does this mean that I have finally cracked the problem ????

 

Replacing the crimpon connectors on the voltage sensing fuse, has stopped the intermittent readings, and the battery capacity hasnt dropped yet... so maybe a new battery is not required after all ... Fingers crossed.

Looks like you have it cracked at last.
