A 15A fuse blew recently in my 2004 120-series, the one for indicators and hazards. I replaced it, and took the 120 to my local independent, who checked for shorts but couldn't find anything obvious. We agreed to wait until it happened again and that I would make a note of which was indicating when it happened.
Yesterday I was on my way to pick up the kids when the fuse blew as I indicated left. I left it like that until I got to the school. A bunch of lights came up on the dash: ABS, VSC, battery, etc.
Then, when I tried to start it after picking up the child, there was nothing. The lights on the dash came on, but no cranking. I replaced the fuse. Nothing. Pulled driver's side battery, took it home in different car, charged overnight using the Optimate, looked fine. Put it back today, wouldn't crank. I have now removed and am charging both batteries. One is almost certainly original fitment (!), and that is a GS Yuasa 85D26P-MF, while the other is a Halfords job that is too long for the battery tray (which is for batteries around 270mm long).
I now recall that twice over the past couple of months the 120 has needed charging after being sat for a couple of days. So, could it be weak batteries that are causing the short? Both look old and tatty, and maybe they are creating electrical problems. Having read this recent thread, I'm thinking of starting by replacing both with Yuasa equivalents, namely this on the driver's side:
https://www.amazon.co.uk/o/ASIN/B00KNQU1VE
and this on the passenger's side:
https://www.amazon.co.uk/o/ASIN/B00KNQTOAI
The specs on these two aren't huge, but I'm not a particularly demanding user, and I do rate Yuasa. And they will fit properly in the battery trays.
EDIT: The YBX5096 would also fit in the tray, and has a bit more power, but there doesn't appear to be a version with terminals the other way round. No big deal, I guess.
Any comments or suggestions?
