Hi. Have had trouble starting my astra intermittently.
The starter sometimes doesn't work.New starter. If I tap the rear yellow relay in box behind battery the thing starts ok for some while.The part no is 90226846 and is a hella relay. the trouble is I am not sure what it does.
Can any body tell me and the cheapest place to get a replacement(preferably on the internet as I live on the isle of wight) Thanks in anticipation
