How can I tell if it's the battery or altenator on my Renault Master Van that's causing the battery & Stop light on the dashboard to flicker on/off? Thanks for your help.
start it....disconnect batt cable...should run down if alt problem....OR...use charger to see what % batt reads---some also have alt testers built in...AND...could just be loose or old sending unit since it's flickering
