Just wondering if anyone can give me some advice about some starting issues I'm having with my C15 diesel van, please.
Over winter I've been having problems starting the van. Some mornings it has taken three or four attempts to get it going, letting the little pig tail light go out a number of times etc etc. I had the battery tested at Halfords at they said it was OK. So I thought the glow plugs might be the problem. Got them taken out, and three out of four weren't working at all. Had them all replaced.. and I'm still having problems. I thought it might be the alternator, but I'm not getting the alternator/battery light come up on the dash. All the lights are working etc. and don't seem to brighten/fade when I rev the engine. So now I'm thinking the battery might actually be buggered and Halfords just tested it wrong or plugged the wrong voltage in or something... I had just driven it 15 miles to get it tested so might that explain why it was showing up as OK? Can batteries lose charge quickly once they're not being used? (If I leave it more than a few hours it won't start properly again..)
I put the battery on mains charge earlier today and the charge rate started at around 4 and within maybe ten minutes it had dropped to 0 (or very close to zero). What does this mean?
Thanks so much for taking the time to read this! Pray it's not my alternator, please...
