Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Do you have a volt meter, can you work in wire testing, can you remove the cluster?
Review this diagram https://dl.dropboxusercontent.com/u/90220402/ICdelay.pdf
The relay you hear clicking is the accessory delay relay. This relay powers the windows and radio. The instrument clusters internal battery saver relay controls the accessory delay relay. Since your cluster is cutting out. That means the focus is on the cluster being bad or it is losing power or ground from bad connections. I could help you test this, but you do not have the tool we need.
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Sorry you were not pleased with my help. What would you like to do now?
The sending unit could be faulty and causing the gauge to read incorrect meaning your issue was caused from running low on fuel. Do you need the diag steps for the fuel gauge reading incorrect?
