Expert: Charles Griffiths Date: 3/6/2008 Subject: relay questions
Question 81 928S- Runs good, but every once in awhile I can turn the key over to start and get "nothing", no click, it will not start and it makes no noise.. I will try again sometimes more than once and it starts.. I've changed the starter, no change, I'm thinking that it is a relay.. but holy shit, there are many relays!.. which one is the starter relay?.. the book says #14 or something like that.. but where is it and how do you know you are replacing the right one????? thanks
Answer Amazing car! Amazing number of fuses and relays under the passenger foot board too. I made it an annual event to rotate all the fuses in their sockets yearly on all three of my sharks over the years.
I could recite the relay numbers, part numbers, and locations however its time you found a good source for information like this and parts as well. Go to https://www.928gt.com/default5.htm which is 928 Spec.
Websites left hand panel has the relay charts. Jeannie and David can help you out.
