Hello,
It has been awhile for me. Almost couldn't fine the forum again. Anyways I have a a YTH21K46 Husqvarna with a SV610 21 HP engine and it will not start. New battery that has 12.4 volts which is good. I was thinking starter since when you turn the key it would click/bump but wouldn't do anything but occasionally would spin for a second. So I proceeded to check the voltage going to the solenoid. I have the same voltage with the key on going to the solenoid. I have also the same amount going down the the starter with the key turned. Still no start however. So took the starter of and proceeded to check it with it unhooked from the mower. When it is hooked up to the battery directly it spins and did soon several times in a row. Hook it back up to the mower and nothing again. Im not a small engine mechanic but I know some of the most basic things to check.
Where to next??
Whos been through this and how did you figure out the issue?
