I've been having a few issues with the car not wanting to start all the time over the last month or so.
Typically it would struggle to fire up in the morning, turning over very sluggishly.
Sometimes I would get rapid clicking like you get when the battery is flat, but it was very temprimental and I was in fear that if I drove it anywhere I'd get stranded.
After some searching on here everything from done batteries to starter motors and alternators being gubbed were suggested but poor earth was suggested a few times by multiple people.
To cut a long story short here is how I solved my problem so you can solve yours if you've done a search and find the same symptoms.
I had been doing some work removing the battery so I probbably upset the conection.
I noticed the terminals were pretty dirty looking so decided to clean them up.
Undo and remove the negative terminal first then before undoing the positive, loosten the top bolt that pinches the terminal to the earth plate/ wire then you can loosten and remove the positive terminal.
I gave it a quick clean with a cloth, and some steel wool with a light spray of wd 40. I did the same with the negative but didn't remove it. I also gave the battery pins a clean the same way.
The same goes for the plates that are on the positive side (remember to clean underneath)
After putting back together I made sure everything was done up nice and tight.
The only thing still to do is put some vastaline over the exposed positive and negative pins to protect them from contamination.
I've read this is an old practice due to older style batteries giving off vapour that can cause corrosion and eventually effect the conductivity of the conection; perhaps someone like Chris Wilson could advise on the corect practice here as I'm unsure.
I've noticed since the clean up the car starts first time like normal and seems to have fixed my problem
I also had a power coupling attached that I had no use for so I removed it incase it was causing an issue.
Can anyone say what I would use this for?
Cheers
