I folks as the title says I got a ktm with a e start problem it keeps blowing the main fuses every time I Push the e start button
I swapped over a lot of bits trying to fault find but no joy even disconnected the two yellow cables coming from the coil or and it didn’t blow the fuse but still won’t start put in a new wiring harness in and still no joy. I’m really at the end of the road now and so disheartened by it
Has anybody ever come across this fault before
Thanks
Peter

Somewhere in the circuit there's a short..could be in a component, or one of the wires. You need to know what all is on the circuit after the fuse to know where to start. I haven't been able to find a wiring diagram for the bike, so I couldn't suggest a starting point....other than an issue that KTM had prior to 2017. Apparently there is a condenser in the circuit which sometimes fails. When it does, the fuse also blows.

Thanks for the reply
I changed as many parts as possible from another 350 (2016) there a brand new loom gone into the bike.

Did you change the aforementioned condenser?

Another possibility is that your starter is starting to bind, likely caused by really dirty brushes, and is now requiring more amperage to start.

Does the bike run if you push start it? Just the actual starter is the problem?

Hi all
the bike still blows the main fuse even if you try to bump start it
the condenser was changed and the stater was changed too

Load test the battery and test the Stator.

Have you ever removed the spark plug cap? When pulling it out or putting it in, there's a chance the rubber tube cracked and its sparking on the inside of the cylinder. Check that.

If not that, there must be a wire loose or water got in somewhere. Did this start after a wash/wet riding day.

You need to trace back what changed before this first happened and that can give you an idea where to look.

Wouldn't cause the fuse to blow....the high amp lead from the battery to the solenoid, and the solenoid to the starter is not fused.
