fuses getting hot

[jt2shot]

my mower is getting the fuses hot they don't blow but they melt the plastic !! the mower run good for a while and then it cuts to half power. I have replaced the regualtor and the clutch this year , the mower has about 1540 hrs on it. my mower is a scag turf tiger 61 in with a kohler 25 hp. NEED HELP BAD!!! a friend said maybe a relay? what do you think?:confused2:

I would renew the fuse holder if the fuse's are not blowing, its pulling Amps so maybe the contacts are not that tight so getting hot, and as you say melting the plastic.

I just check the relay took one off my buddys mower and it still does the same. and we check the fuses and the holder fuses are tight even hard to get out one might say.
:confused2:

And what about the connections to and from the fuse holder.

ok I just found out that the seat switch does not shut off the mower when you get off. but it still works for the start up. you have to be on before it will start. but you can dismount while mower and blades are on. not safe but what controls that . the seat switch checks out with tester.

This may help you out.

Thanks I just found that the coil pack on the right side is dead. I guess it worked until it got hot. would this make the fuse get hot??????

I would be looking for a wire that has a crack in the insulation causing and intermittent short. Second what size fuses are in there? They may be too big for the system and don't blow. Third is it one or both fuses? Finally, do you have the ammeter? If so what is it reading?

I would have thought so if it was shorten. replace coil and you will soon know...!

Welcome back Rivets, are you thinking that the gen is giving out too many amps...!
