cant keep a runniing light fuse in my 08 roadglide instant pop any
body had this problem?

 

Check for a bad or dirty connection around The light Relay. Failing that check any add on accessorys especially any lights.

 

thanks for the advise it seems the front turn signal wire was pinched
where it comes through the fairing lesson 1 start with the basics

 

Control housings on the handlebars are another common place where wires get pinched. Also, inside the fairing, any wires laying on the radio heat sink will wear through and ground out. Both these happened to me...
