Blowing Fuse when hit Starter

[Krlee99]

I have a 2001 Ski Nautique with GT-40.

When I hit the start button it blows the fuse on the battery cable. I have replaced the Starter, Starter Relay and two other starter relay's (small black boxes) on the motor and still have the same issue.

Have checked the battery and cables for issues, everything is good there.

Could it be the key pad?

Anyone else have this issue?

It sounds like you might have a worn cable that is grounding out when the starter relay makes contact. Follow your positive cable from beginning to end and make sure there are no worn spots.

bad ground. The power from your batter does not send - it pulls. So if something is pulling enough juice to pop the circuit there is to much juice getting requested. In these cases there is almost always a bad ground associated. A faulty ground can essentially cause your current back trace, this is literally like the ground going up stream to try to ground. A bad ground can also, cause to much power to be requested because the polarity is weak, then suddenly there is a huge spike of energy when the draw happens and poof, your fuse goes.

Take a look at your starter solenoid. The starter feeds from a master solenoid and then to the alternator. If your master relay is bad which can happen what you are describing will occur If the starter itself is bad it will also occur. If the alternator is not grounded right this should not occur, at startup , however would occur once the engine is running.

I would put my money on the starter solenoid or the master solenoid.
