The cable that goes from the battery positive to starter has a block on it, is this a fuse?
The connector to block has snapped and car wouldn't start, can I repair this, is it a fuse, if so, what rating is it and can I add another one onto the existing cable, I am a carer in a care home and need to be able to get to and from work. I also have autistic children that require me to come to and from work to home when they have a melt down, I please need someones help.
