When I first checked the hydrometer I thought that the float might be stuck to the side of the glass as the float did not rise at all. After some jiggling I tried a second hydrometer but found the same result. The battery acid (such as it is now) had a specific gravity of less than 1.1, as low as the hydrometer will read. I have never encountered a battery with a specific gravity this low. |
The charge controller has two glass cartridge fuses. On our last trip we found one of them blown but lacked a replacement. Fortunately Ken (WA7PIX) had a 25 AMP blade fuse and some small jumpters so we were able to get the repeater back on the air. After replacing the fuse I left the remainder of the box at the site so we have some spares up there. |
