2002 SC50tx power issue

[a1stump]

I have a 2002 Vermeer SC50tx with a 3024 cat 50hp engine. I turn the key in the on position, computer and display light up as they are suppose to, but in less than 5 seconds, makes a clicking sound like the circuit breaker tripped and all power and lights are lost. Leave the key in the on position and in exactly 15 seconds, it lights up again for a second or two and then trips again. Starting is not an option.

Sounds like a knackered battery

Look, I know it's obvious, but I don't know you're mechanical ability, have you checked the battery and tried to jump it?

sometimes if theres a bad earth going to the ecu if you bridge the starter with ignition switched on the engine may start stick a meter across the battery to see how much of a voltage drop there is during starting then work along the main battery cables to see if there is any drop along each cable the first thing i would do is check the battery as others have said
