Good old 'Murphy' paid me a visit yesterday!
In the first couple of days of our recent trip, both LED water tank gauges stopped working. These are mounted next to the solar/batteries meters. They are operated by pushing a button on the face of the gauge.
I put the cause of the malfunction to a loose connection somewhere, caused by the somewhat corrugated surfaces we had been travelling on.
Yesterday, I commenced my sleuthing, with the removal, inspection and replacement of both tank sensors. I had no idea what to look for but they appeared OK to me.
I then started the lengthy and awkward process of following the relevant wiring through the 'van to the inside electrical panel. My dodgy back is not too flash when working under a vehicle or in crawl spaces.
After some time and a calming cup of tea, I ended back at the panel, with the circuitry testing OK on the multi-meter.
I then had a closer look at one of the gauges and noticed a small gap on one end, which appeared designed to have a wee lever used in it.
On opening the gauge, Lo and Behold! There was a small A23 battery inside.
After a drive to my local IGA, purchasing some replacement batteries, inserting a replacement and trying the button, 'Voila'!
All the LEDs lit up, as the tank was chockers. The same with the rear tank gauge.
Now, my question is, 'What are the chances of both batteries going flat on the same day, even if they were replaced at the same time plus, me commencing at the wrong end of the wiring?"
