F225 Clicks but starter does not engage

[pcww]

I have a 2005 F225 that up until now, with 700 hours has been fantastic. It is a dual setup on a Grady White Chase 273. When I turn the key the alarms go on and I believe I am getting juice to the motor since I can hear an audible click. Sounds like the solenoid or relay is either defective or not engaging. I thought I read where this is a common problem. Any ideas? If so is it something a diyer could do. Thanks. Henry

Does the power to the gauges etc go off when you turn the key to try and start the engine i.e. power comes on when the key is turned one click, and then goes off as you try to turn the starter? If so, it is probably a bad battery or bad cable. Bad cables are a very common cause of this symptom.

the click you hear is the starter solenoid picking...when you are trying to start it what reading do you get on the positive post on the starter?..compare this reading to the battery positive post....a fully charged battery will read 12.7 volts before you try to start the engine...the reading on the starter post should be 10.5 or better when trying to start..
