I have an AL-KO KHS 5200L log splitter, it is tripping the main fuse when attempting to start, I have been using the machine on a regular basis but now it just trips the fuse, the circuit board fuse on the circuit is 16a but that does not trip.

If it's knocking out the main trip next to your meter, I'd guess it's a dead short either in the log splitter on off switch or across the motor windings. I take it it doesn't trip just by plugging it in, but when you turn it on?

Hi SP.
Just trips when turning on, there is a small movement in the motor then it trips.

If it is kept in a shed or a barn it could be a build up of condensation in the on/off switch. I would check there first for signs of damp and any tracking marks(black or brown burn marks across the connections) Then maybe disconnect the live connection to the motor and see if it still trips. If it does it sounds like the switch, if not probably the motor. Also make sure no cables have got trapped in any part of the machine.
It goes without saying, only attempt this if you know what you are doing. If you don't have a reasonable knowledge of electrics leave it to someone who does or you put yourself at serious risk.

Thanks JP.
I will be stripping down tomorrow, will look for the signs you suggest.
I have a great respect for electricity dating back to a day when I saw a maintenance engineer blasted across a workshop by three phase leccie, he survived.

Hopefully it's the start capacitor, no reading at all from it.

Ok, fitted new capacitor, ran for a few minutes then tripped fuse again. Decided to dismantle the motor, when I removed the cover some brown water ran out, must be condensation from being stored in the garage over two months without use. Question is can I clean the winding where it has been contaminated by the water, hopefully that would solve the problem. Or maybe just let it dry out?

Personally, I'd bring the motor indoors (if possible) where it's warm, to dry out, then clean the windings. Seems a lot of water damage for condensation, maybe you had it stored up a drip?

I'm assuming condensation as no sign of any water in the area from leaking roof etc. Any suggestions as to what to use for cleaning the winding, I can't remove it, tooooo complicated for me, maybe WD40 and a toothbrush?
