Timer waits for no-one - Neither do inline fuses!

I didn't drive the Vogue today - there were too many obstacles.
Firstly, last night I plugged into my wall timer and checked that is was set to auto - only to find that it had stopped entirely. The timer is a Chinese copy of the TP8A16, 16A 240 VAC timer.

It was designed to come apart, so come apart it did!

The 1.2V, 80mA/h NiMh button battery had EXPLODED.

I removed the cell and checked out the rest of the board - it appeared fine after a little cleanup.
A quick reverse engineer and I discovered that they use the battery as a 1.4 volt regulator. Without the battery there is about 6 volts at that point. The electronics doesn't like that so it didn't work. When I turned off the 240VAC, it worked for a few seconds as the voltage went down through the acceptable region. So the electonics was probably OK (amazing).

I removed the exploded cell and substituted two diodes in series where the battery used to be. It all worked fine. It only lasted about 5 seconds after mains disconnect but that would do for the night.

At least they used a 16 A relay.

I went out to the car at around 6:45AM this morning to check all was well (timer was set to start at 5AM and finish at 8AM) - but all was not well. I charge at 3 Amps and needed 6.6AH - so a bit over 2 hours required.

Battery pack #12 was indicating finished charging - all the rest were still charging as they should have been.
I checked pack #12 and it certainly wasn't fully charged - another inline fuseholder! I should have had them all changed out by now - oh well. previous fuseholder failure

Pack #12 is under the controller tray and hard to get at so I'll take my daughter's car as she is not due home until Thursday and I have to give it a full tank and wash it anyway.
That way the Vogue is also in the carport for some wiring surgery tonight. I'll try to bypass all three fuseholders under the engine bay without removing the controller tray. I'll see how I go...
