will bad ground cause intermitten ignition problem and intermitten battery light?
yes first thing to do is clean battrey posts and body ground cable
yes, corrosion, weak connection, anything can cause this. Clean the posts and any ground connection you can get to. Make sure the connections are snug and not going anywhere.
Thanks so much for your responses - seems to be working -so fsr so good- removed and cleaned cables and found ground to block loose-removed and cleaned connector and put on good and snug Thanks againAndreww and Karl
