Hi friends, I have a maxum with a 4.3l thunderbolt v set up, we have just purchased this boat knowing it wasnít running, it tries to start then as soon as you turn the key for a 2nd time it clicks rapidly, Iíve had the battery tested and itís perfect, (also tried 2 other batteries) and had it on jump start with the same rapid clicking, the tilt trim also works on the 1st attempt to start then it clicks rapidly trying to use it after the 2nd attempt of starting, iitís definitely not a battery issue (which seems like the obvious answer) Iím assuming it might be an earthing fault? Iíve cleaned the main earth on the back of the block and at the battery, also put in a new starter motor, starter solenoid, relay, and coil pack, leads and plugs. Iím absolutely stumped as to why it tries to start 1st attempt when cold then nothing there after, same result 4 weekends in a row. Please if anyone has any proper input help! Much appreciated.
